The Marine Environment – Aquatic Nuisance Species (ANS)

Zebra Mussels

Many states are beginning a proactive approach  to enforce laws that many boaters may not even be aware of. The effort aims to assure that boaters do not accidentally spread Eurasian water-milfoil, zebra mussels, and other aquatic invasive species to other bodies of water. Inspectors will be stationed at various bodies of water to help boaters understand invasive species laws and what they must do before leaving that body of water.

Aquatic nuisance species (ANS) are non-indigenous species that threaten the diversity or abundance of native aquatic species. Two such ANS are the Zebra mussel and the Quagga mussel. Great Lakes water users spend tens of millions of dollars on zebra mussel control every year. Zebra mussel infestations cause pronounced ecological changes in the Great Lakes and major rivers of the central United States.

Giant Salvinia

Non-indigenous aquatic nuisance plants, such as purple loosestrife, Eurasian water milfoil, giant salvinia and hydrilla quickly establish themselves. Environmental and economic problems caused by the dense growth of these weeds include impairment of water-based recreation, navigation, flood control, water quality and fish and wildlife habitat.

Invasive species can crowd out native species, disrupt lake ecosystems, and interfere with boating, fishing and other recreation. The main way that invasive species and fish diseases such as viral hemorrhagic septicemia (VHS) spread to new waters is aboard boating and fishing equipment, boat trailers, water in livewells and live fish being moved from one water body to another.

Boaters, anglers, and others enjoying the waters of many states are required to:

  • Drain all water from vehicles, trailers, watercraft, containers, fishing equipment, and gear when leaving any state waters or its shores.
  • Do not take live fish away from any lake or its shores. A fish is considered dead when it is no longer in water. This law applies to shore anglers as well as those who fish from a boat.
  • Remove all aquatic plants, animals and mud from watercraft, trailers and vehicles before leaving a landing for the day. Do not transport a vehicle, boat, boat trailer, equipment, or gear of any type on a public highway which has an aquatic plant or animal attached to the exterior.
  • Use minnows left over after a fishing trip again on the same water OR on any other waters if no lake or river water, or other fish was added to their container.

Please consult with your state marine patrol and local marinas to identify non-indigenous species in your area. For more information on Impacts of Aquatic Non-indigenous Species, visit http://www.protectyourwaters.net/impacts.php

Coast Guard reminds boaters to be safe during Lobster Mini Season

The Coast Guard reminds all divers and the boating community to be safe this lobster mini season, Wednesday and Thursday.

The lobster mini season brings with it a significant increase in the number of boaters and divers in Florida’s coastal waters and this increase in boating activity can lead to accidents if boaters and divers forget to practice safety first.

The Boating Advisory Trailer – Public Awareness Kit (BAT-PAK) will continue its safety outreach tour throughout the Florida Keys during the last week of July.

Some safety tips to remember before and during a dive:

  • Check your dive gear before your dive and monitor your air during your dive.
  • Do practice dives before the season starts. Use the preseason time to refresh your skills and improve your fitness. Remember that an underwater hunt is more stressful than a recreational dive.
  • Do not dive outside your physical capabilities.
  • Ensure you have a dive plan and are diving with a buddy.
  • File a float plan with a family member or a nearby marina.  Stick to a time frame while diving and let someone know if it changes.
  • Ensure you are wearing reflective material on your dive suit.
  • Mark the area in which you are diving with a dive flag and a light.
  • While piloting a boat, stay aware of your surroundings. Remember divers can get separated from their flags and boats.
  • Remember, taking all the basic safety precautions will facilitate an increased chance of helping or finding a diver in the event Coast Guard assistance is needed.

Boats engaged in diving should show a rigid replica of the internationally recognized “Alpha Flag”. This is a blue and white flag with a swallow tail. Additionally, the traditionally used “Divers Down” flag should be flown from the boat or from a float over the divers. This red flag with a diagonal white stripe should be easily seen on the water.

Personnel from the Coast Guard, Florida Fish and Wildlife Conservation Commission and other agencies will patrol the waters surrounding South Florida to ensure compliance with federal and state regulations.

Prohibitions: Harvest of lobster is prohibited in John Pennekamp Coral Reef State Park during the sport season.  Harvest is also prohibited during both the two-day sport season and regular season in Everglades National Park, Dry Tortugas National Park, and no-take areas in the Florida Keys National Marine Sanctuary.

Boaters Must Consider the Effects of Prescription Medication

Courtesy U.S. Coast Guard Auxiliary Public Affairs Office –

Prescription medications can bring on unwanted side effects to boaters on the water far from emergency personnel. “The marine environment exposes people to heat or cold, motion, wind, noise and other factors that can cause fatigue in anyone,” says Richard C. Lavy, M.D. The physical condition of everyone on board should be assessed before leaving the dock. Lack of shade and over exposure to the sun and heat along with ever changing sea conditions can bring on dehydration, dizziness and heat exhaustion. Drowsiness or confusion will impair the ability to operate a boat safely much like too much alcohol.

Recognize the signs of medical distress and know how to call for help. Depending on geographic area, use VHF marine channel 16 or call 911. Know before you go.

 Remember this acronym – BOAT SAFE – it stands for

–  Bring plenty to eat and drink – avoid dehydration

–  Operate the boat in a safe and responsible manner

–  Always wear a life jacket

–  Take a boating safety course

–   Sun, wind and temperatures can be more of a factor than boaters think

–  Annual courtesy vessel safe check

–  File a float plan – leave it with someone who will take action if overdue

–  Evaluate the readiness of operating crew and passengers – it is ok to not get underway when there is doubt

But I Don’t Want To Be In Charge! Part 2

The last article focused on suddenly finding yourself in charge of a small outboard vessel, but what if the owner/skipper is suddenly injured, becomes ill or falls overboard on an inboard boat or, worse yet, a large inboard twin engine. Once again, you were just along for the ride, you don’t know anything about the boat, about what to do or how to do it – but…suddenly YOU are in charge. Suddenly, YOU need to know how to run the boat, YOU need to know how to use the emergency equipment, YOU need to know what to do in each situation that requires action. Don’t wait until YOU are suddenly in charge, learn the basics before just “going along for the ride”.

Learn Boating Basics

The basics are the same no matter what size the boat you find yourself on; you need to know the location of the Personal Flotation Devices (PFDs), the fire extinguisher(s), emergency signaling devices and other safety gear. You also need to know how to operate the VHF radio and how to lower the anchor. These two items may be your lifeline to safety.

Again, it is a good idea to take a Basic Boating Safety Course even if you don’t own a boat. The more time you take to educate yourself the more likely you will be a hero rather than a hindrance, should an emergency arise.

Pay Attention To The Basics

Rather than just sit there in the “co-pilot” seat looking at the sky and the water, look around, ask questions, watch what the owner/skipper does. This article is not intended to make a novice an experienced boat handler but we hope to at least get the inexperienced person to some level of comfort with what he/she sees around them.

Note the typical cockpit layout below. You have electronic equipment such as a VHF radio, Depth Finder, GPS. You also have the controls and sensors for operating the boat such as the clutches (which shift gears), the throttles (which control the speed of the engines) and the various gauges which you should monitor as you do in your car.

This layout is for a typical twin engine vessel. A single engine will have only one clutch and one throttle. Pay particular attention to the RED knobs on the throttles. They are so marked to make sure that you don’t forget which you are handling. You wouldn’t want to be in a close quarters situation and think you were shifting from reverse to forward while accidentally pushing the throttle forward instead of the clutch.

Safety Hint: When using the clutches, if there are two, keep both hands on them. This will help prevent you from accidently hitting the throttle. If there is only one clutch, put one hand on it and the other behind your back.

Lesson One: How Do Clutches and Throttles Work

The throttles on a boat act like the accelerator on your car with one exception; You shouldn’t operate them with your feet. The throttles, usually marked with red knobs, are at idle when they are pulled all the way back toward you. As you move them forward, the fuel supply to the engine(s) is increased and, assuming you are in gear, you move faster.

The clutches, with the black knobs, act like your gear shift. When the lever is standing straight up in the middle you are in neutral. When you push the lever forward you are engaging the forward gear and when you pull the lever back you are engaging the reverse gear.

Important: Never change gears without first pulling the throttles to idle speed (neutral)!

Lesson Two: How Does An Anchor Windlass Work

The vessel on which you find yourself suddenly in charge may or may not have an anchor windlass (assists in raising and lowering the anchor by electric motor). If it does not, then the anchoring is fairly straightforward as outlined in the Nautical Know How Basic Boating Course STEPS TO SMOOTH ANCHORING. However, if you find yourself on a vessel with an anchor windlass the steps are the same, just the release and retrieval of the anchor are different.

The picture at left is a typical small boat (38′) electric anchor windlass. The first step in operating such a system is to make sure that you have power to the windlass.Normally, when underway the main breaker to the windlass will be turned on but there is usually a switch in the cockpit which disables the power temporarily. This is so that you don’t accidentally step on the up and down switches on the deck while underway or while handling lines on the bow. Make sure that the cockpit switch is on.

Notice that the anchor rode (chain/line that attaches the anchor to the boat) is cleated off on the port side to secure the anchor up and that the remainder of the rode leads through the “hawspipe” (to the left of the “UP” switch) into the anchor locker.

The first step to lowering the anchor is to remove the cap from the hawespipe. As a rule of thumb, you want to put out anchor rode which is 7 to 10 times the water depth. Pull enough anchor rode out of the locker and lay it out neatly up and down the deck.

Next, uncleat the anchor rode on the port cleat which was holding the anchor securely and recleat the rode at the maximum amount of scope you expect to let out. Make sure the boat is completely stopped and, once the rode is cleated, you simply step on the down button and the windlass will lower the anchor. Make sure that you keep your hands and feet clear so you don’t get tangled in the anchor rode and get pulled off the vessel.

Lesson Three: How Does A VHF Radio Work

The vessel’s VHF radio is fairly simple to operate and if the owner/skipper was operating legally, it should already be tuned to channel 16 which is the hailing and distress frequency. For more information on VHF radio procedures look at Marine Radio Procedures in the Nautical Know How Tips Archive. In order to call for assistance, hold down the “transmit” button on the side of the microphone and speak directly into the mike. Once you have delivered your message, release the button and wait for a response.

Let’s explore two different scenarios in which you might find yourself. Whether you are in a single engine or twin engine boat really doesn’t matter. As was mentioned above, we aren’t going to make you boathandlers, just emergency situation solvers.

Situation One

You have just left the marina and are heading out for a day of coastal cruising. The owner is operating the boat through the well marked channel and has explained to you that it is important to keep within the channel which has sufficient depth to safely operate. He/she has shown you how to read the depth finder and you find that the channel has a consistent depth of 8 feet.

Suddenly the owner, who doesn’t look so good all of a sudden, collapses and falls out of the chair behind the wheel. What should you do?

Your first reaction should be to try and get the owner, now victim, to acknowledge his or her situation. Ask if they are okay. Even if they are unconscious and not breathing, there is nothing you can do until you have control of the boat.

You should first take off all power and shift to neutral. While the boat coasts to a stop try to steer toward the edge of the channel. Assuming you are not in immediate danger of drifting out of the channel or running into another vessel, check the condition of the victim again.

Let’s assume they have simply fainted and are still breathing and have a pulse. Attempt to contact the marina that you just left via VHF radio and advise them of the situation. Explain that you are not experienced and that you need immediate assistance. Give them your location by noting the latitude and longitude on your GPS or simply note the channel marker number that you might be closest to.

Depending on your comfort level in actually operating the vessel, you should either consider anchoring, tending to the victim and waiting for help or putting the vessel in forward and turning the vessel to return to the marina. If you chose the latter, do so under control. You don’t necessarily need to go at full idle but don’t overdo the speed. Remember, boats don’t have brakes and you can only stop them by running into something, running aground, coasting to a stop in neutral, or shifting to reverse at full idle.

Situation Two

You are offshore, within sight of land, and headed for a favorite fishing spot that the owner has programmed into the GPS. In this case the owner is a he and he tells you to take the wheel while he goes to relieve himself. No problem, anyone can steer a boat- so you settle in as commanded.

The water is not too rough but an occasional wave that is considerably bigger than the rest comes along and tosses the boat slightly. Suddenly you hear a scream and a splash and look aft to find that the owner was thrown overboard off the stern by that last unexpected wave. What should you do?

You should first pull the throttles to idle and simultaneously shift the clutches to neutral. Immediately throw the Type IV throwable device in the direction of the victim in the water. Try to keep focused on the individual in the water. Don’t lose sight of him.

Once you have something that floats in the water in the vicinity of the victim it is time to attempt the rescue. After making sure the victim is clear of the props, shift the clutch(s) into forward and at idle speed make a U-turn and head back toward the victim in the water.

Make sure to turn the bow toward a person in the water, swinging the stern (and props) away from them. Since he is conscious and can swim, don’t get too close. Approach from downwind so that he floats down to you, not the boat floating down on the victim.

Be sure to shift to neutral well before approaching the victim and coast to a stop short of him. From here, try to throw a line and a PFD to the victim in the water. Once you have him attached to the boat, do not use the clutches.

Conclusion

The two scenarios above were dangerous but obviously could have been much worse. For instance, what if the person in the first scenario wasn’t breathing and didn’t have a pulse and what if you didn’t notice the person in the second scenario go overboard? What would you do then? Give it some thought, it could happen.

But I Don’t Want To Be In Charge! Part 1

As a friend of mine once said, the only thing better than owning a nice boat is having a good friend who owns one. None of the headaches, none of the problems, none of the responsibility but all the fun when asked out to enjoy the water. But what happens when your friend, the owner and skipper, is suddenly injured, becomes ill, our worse yet, falls overboard? You were just along for the ride, you don’t know anything about the boat, about what to do or how to do it – but… suddenly YOU are in charge. Suddenly, YOU need to know how to run the boat, YOU need to know how to use the emergency equipment, YOU need to know what to do in each situation that requires action. Don’t wait until YOU are suddenly in charge, learn the basics before just “going along for the ride”.

Learn Boating Basics

Even if you don’t own a boat, if you ever go out in one as a passenger, you should know the basics of boating. Even if you’re just going for a ride, if the skipper doesn’t give the passengers an orientation, ask where the emergency equipment is located.  Ask the location of the Personal Flotation Devices (PFDs), the fire extinguisher(s), emergency signaling devices and other safety gear. Practice throwing PFDs or a line to a pretend person overboard, practice anchoring the boat and getting aboard from the water. Ask about the operation of the boat, how do you start it, how do you stop it and how to use the radio (if equipped). Better yet, even if you don’t own a boat, take a Basic Boating Safety Course. The more time you take to educate yourself the more likely you will be a hero rather than a hindrance, should an emergency arise.

This article covers basic operations of small outboards. Future articles will cover larger powerboats and sailing vessels.

outboardLearn How to Start Manual or Pull Start Outboards

  • Make sure the shift lever is in the neutral position. This is usually straight up.
  • If the engine is cold, pull out the choke before attempting to start. If the motor is warm, don’t use the choke unless the engine does not start after a few pulls.
  • On the throttle control arm, turn the hand grip until the arrow aligns with the start position.
  • Pull the starter rope slowly until you get resistance from the starter gear, then pull forcefully. Repeat if needed.
  • When the engine starts, if you used the choke push it in slowly until the engine runs smoothly.
  • Turn the throttle control arm until the arrow lines up with the run or shift mark.
  • Warning: Do not stand in the boat to pull the starter rope. If the motor is in gear or the starter just spins, you could loose balance and fall overboard.

Learn How to Start an Electric Start Engine

  • throttleSqueeze the release lock on the shift/throttle control lever, and make sure it is in the neutral position, usually straight up.
  • If the engine is cold, move the warm-up lever to the start position.
  • You may find a choke switch or the choke may operate by pushing the key in which activates an automatic choke.
  • Hold the key in or use the choke switch and turn to the start position. Release the key or turn off choke switch as soon as the engine starts.
  • Gradually move the warm-up lever to the run position.
  • If the engine is warm, use the same procedure with the exception of using the choke, unless the motor fails to start after a few tries.

Learn How to Shift and Steer

throttleManual or Pull-Start

  • The throttle arm also acts as a tiller to turn the engine which gives you direction.
  • Look out for traffic and find out the direction you want to go. Move the throttle arm/tiller in the opposite direction. This pushes the stern of the boat in the direction of the tiller which in turn makes the bow go in the opposite direction.
  • Turn the throttle arm until the arrow lines up with the run/shift position.
  • Move the shift lever to forward (or reverse) and turn the throttle handle slowly until a comfortable speed is reached.

Electric Start

boat handling

  • Squeeze the release lock on the shift/throttle control lever. Push the lever slowly forward to go forward and pull slowly back to go in reverse. The further forward or back you push the lever the faster the boat will move.
  • Steering with a wheel is much like a car in that you turn the wheel (helm) in the direction you want to go. Be careful however, because unlike a car, a boat steers from the stern (back) rather than the front as a car does.

Warning: Go slowly in reverse to prevent water from spilling in over the transom.

Learn How to Stop

Boats don’t have brakes. They do, however, settle quickly and slow down when power is lowered and the engine put in neutral.

Don’t aim the boat at a person in the water or at a dock. If you misjudge the speed of the boat you could cause more damage.

As the boat slows you will loose steering control. Aim the boat where you want to stop before you shift to neutral or shut of the engine. Shift to neutral before you think you should, most novices overshoot their mark. You can always shift back to forward briefly if you fall short of your mark.

Killing manual or pull-start engines

Shift to neutral, turn the throttle handle grip to the stop position and push the button (usually red) labeled stop which kills the engine.

Killing electric start engines

Shift to neutral, turn the key to the left until the engine dies – just like in your car.

Learn Crew Overboard Procedures

Be Calm – You may be the only source of rescue for the person in the water.

Immediately shut down the engine unless you can see that the person in the water is well clear of the boat and will not be hit by the props. Locate the person in the water and keep an eye on them. If they are close enough, throw a PFD or anything that floats in their direction.

If you must, restart the engine and move slowly toward the person from downwind (the wind in your face). You don’t want to drift into the person when you stop the engine. When close enough, throw a PFD or anything that floats and stop the engine.

Once the person in the water has something to help them float, tie one end of a line to the boat and throw the other end of the line to the person in the water. Once the person grabs the line, pull them slowly to the boat.

Try to get a PFD on the person or tie the line under their arms and tie up short to the boat so they can rest. If you can not easily lift the person into the boat it is best not to struggle; call and wait for help. Continuing to try to pull the person into the boat could result in you going overboard.

Lower the anchor to keep from drifting and wait for help.

Learn How To Signal For Help

Certain signals are recognized internationally as distress signals. A few easy to use are:

  • Raising and lowering your outstretched arms.
  • Use a mirror to reflect the sun’s rays. On a sunny day the reflection can be seen for miles.
  • Signal SOS (··· — ···) with a flashlight, whistle or horn.
  • Light or fire off a distress flare. Be sure to read the directions on the flare and light or fire downwind and over the side of the boat. It is best to do this when in sight of land or another boat. A flare is not all that obvious on a bright, sunny day.
  • Yell. Your voice will carry a long distance over water.
  • If equipped, use the VHF radio to place a call on channel 16.

Why Should I Carry One If It Is Not Required?

Everyone should by now be familiar with all the USCG equipment required to be on you boat before leaving the dock but is it time to rethink that list and add something? What about an anchor? An anchor is not required to be onboard but every vessel should have one. Even if you are not planning to stop and anchor for lunch, a swim or to fish, you should have an anchor rigged and ready in case of an emergency. Rigged and ready doesn’t mean that it is in a locker or under a seat with a case of soda on top of it. You should be ready to deploy an anchor in a minute or less. I have witnessed many small boats end up on jetties or run aground when they lost power and had no way of controlling the progress of the boat.

Different types of anchors.The first step in anchoring is to select the proper anchor. In spite of claims to the contrary, there is no single anchor design that is best in all conditions. On most pleasure boats, the three anchors you will find most are the fluke or danforth type, the plow and the mushroom anchor.

Mushroom anchors do not have the holding power of a fluke or plow anchor and should only be used on small, lighter weight boats. A local marine supply store can help you select the proper anchor for your boat and for the waters in which you will be boating.

Anchors also must have something to attach them to the boat. This is called the anchor rode and may consist of line, chain or a combination of both. The whole system of gear including anchor, rode, shackles etc. is called ground tackle.

The amount of rode that you have out (scope) when at anchor depends generally on water depth and weather conditions. The deeper the water and the more severe the weather, the more rode you will put out. For recreational boaters, at a minimum you should have out five to eight times (5 to 1 scope for day anchoring and 6 to 8 to 1 for overnight) the depth of the water plus the distance from the water to where the anchor will attach to the bow. For example, if you measure water depth and it shows four feet and it is three feet from the top of the water to your bow cleat, you would multiply seven feet by six to eight to get the amount of rode to put out.

How to anchor safely.

Below is a list of steps to anchoring but I should point out first that before you anchor in an emergency make sure you look all around you and make sure there is not a large barge or other vessel bearing down on you.

  • Select an area that offers maximum shelter from wind, current, boat traffic etc.
  • Pick a spot with swinging room in all directions. Should the wind change, your boat will swing bow to the wind or current, whichever is stronger.
  • Determine depth and bottom conditions and calculate the amount of rode you will put out.
  • If other boats are anchored in the area you select, ask the boat adjacent to the spot you select what scope they have out so that you can anchor in such a manner that you will not bump into the neighboring vessel.
  • Anchor with the same method used by nearby boats. If they are anchored bow and stern, you should too. If they are anchored with a single anchor from the bow, do not anchor bow and stern.
  • Never anchor from the stern alone, this could cause the boat to swamp or capsize.
  • Rig the anchor and rode. Check shackles to make sure they are secured with wire tied to prevent the screw shaft from opening.
  • Lay out the amount of rode you will need on deck in such a manner that it will follow the anchor into the water smoothly without tangling.
  • Cleat off the anchor line at the point you want it to stop. (Don’t forget or you’ll be diving for your anchor.)
  • Stop your boat and lower your anchor until it lies on the bottom. This should be done up-wind or up-current from the spot you have selected. Slowly start to motor back, letting out the anchor rode. Backing down slowly will assure that the chain will not foul the anchor and prevent it from digging into the bottom.
  • When all the anchor line has been let out, back down on the anchor with engine in idle reverse to help set the anchor. (Be careful not to get the anchor line caught in your prop.)
  • While reversing on a set anchor, keep a hand on the anchor line. A dragging anchor will telegraph itself as it bumps along the bottom. An anchor that is set will not shake the line.
  • When the anchor is firmly set, look around for reference points in relation to the boat. You can sight over your compass to get the bearing of two different fixed points (house, rock, tower, etc. ) Over the next hour or so, make sure those reference points are in the same place. If not you’re probably dragging anchor.
  • Begin anchor watch. Everyone should check occasionally to make sure you’re not drifting.
  • Retrieve the anchor by pulling or powering forward slowly until the anchor rode hangs vertically at the bow.
  • Cleat the line as the boat moves slowly past the vertical. This will use the weight of the boat to free the anchor and protect you from being dragged over the bow.
  • Once free, raise the anchor to the waterline.
  • Clean if necessary and let the rode dry before stowing away.

Another App That Could Turn Your Smartphone Into a Fishfinder

After a few futile hours at the pond with a fishing-rod many begin to wonder what it would be like using one’s smartphone to see where all the fish hide. Friday Lab created the first smart sonar Deeper in the world both for amateur and professional fishermen. It is the sonar that can show you where to look for fish directly on the screen of a tablet computer or a smartphone.  If you could not brag about great catches until today, with Deeper you will always bring fish home.

Deeper is a smart sonar for smartphones and tablets supporting Android 2.2+ and iOS 4.0+ operating systems.  The smart sonar works in the depths from 0.5 m to 40 m and uses Bluetooth connection to display the information about the fish, the pond bed, water temperature and obstacles you may bump into, on the screen of a phone or a tablet.

With Deeper sonar you can go angling in any weather: the device works in the temperatures from -10 to +40 degrees. When angling from a boat, a coast or a bridge, you can observe the situation on the screens of your smart devices within 50 m radius. Deeper turns on and is activated only when immersed in water, that way it extends its working time so in unfavorable conditions there is no need to take off your gloves or other protection to get a grip on small operational buttons.
 
Deeper sonar is very compact and ergonomic, being only 6.5 cm in diameter and made in such a way that it cannot be damaged by water. The sonar is resistant not only to water, but also to small shocks. The lithium ion battery ensures about 6 hours uninterrupted operation of the echosounder and Deeper can be charged using a conventional Micro USB cable.
