Test Your Own Nautical Know How – The Answer

On December 18, 2009 an article was published featuring the barkentine, Gazela, sailing vessel.

Toward the end of that article the question was posed: “What are those furry, caterpillar looking things attached to the rigging called?”

Frank correctly identified the purpose but not the nautical name.

“Baggy Wrinkle” is chafing gear fashioned out of old hemp rope and wound on the mast shrouds to protect the sails from damage.

Below, Boston University Students are learning to make Baggy Wrinkle.

Risk of Collision – How Do You Know?

When two power-driven vessels are in sight of one another and the possibility of collision exists, one vessel is designated by the rules as the stand-on vessel and the other is designated as the give-way vessel. The stand-on vessel should maintain its course and speed. The give-way vessel must take early and substantial action to avoid collision.

If it becomes apparent that the actions taken (or not taken) by the give-way vessel are dangerous or insufficient, the stand-on vessel must act to avoid collision.

So, how do you know a risk of collision exists? An example: your boat and another boat are on a course with a constant bearing but a decreasing range. You are both heading to the same point at the same speed. The risk of collision exists if neither of you alter course and/or speed.

To see this in action watch the following video. After watching, let me know,  in the comments section, who should have been the stand-on vessel and who should have been the give-way vessel.  Also, what rules of the road were violated?

Yard Patrol Craft – YP

If you read the December 14 post, “The Most Boats Win…and So Can You”, the question was asked “What does the YP in the YP class Navy vessels stand for?”

One of our readers, Todd, came up with the correct answer, Yard Patrol.

Todd, please send your snail mail address to me at and we will get your Nautical Know How “BoatSafe” tee-shirt on its way to you.

Meanwhile some further information on the Yard Patrol Craft follows courtesy of the United States Navy Fact Sheet.

Yard Patrol craft are used for training and for research purposes.

The YPs are used to teach familiarization with water craft, Basic Damage Control and underway instruction of Basic to Advanced Seamanship and Navigation. Yard Patrol craft provide realistic, at-sea training in navigation and seamanship for midshipmen at the U.S. Naval Academy in Annapolis, Md., and candidates at Officer Candidate School, Pensacola, Fla. These craft can cruise for 1400 nautical miles at 12 knots for five days without refueling.

The YPs are used at the Naval Undersea Warfare Center Division, Keyport, Wash., to measure mobile underwater target and torpedo radiated noise plus ambient water noise conditions; serve as a platform for deployment of suspended, stationary, in-water acoustic targets during on-range torpedo proof and test operations; deployment of countermeasure emulator during torpedo operations; and deployment of oceanographic measurement instrumentation to determine seawater conductivity and temperature at the depth(s) of interest.

The new Training Patrol Craft (YP) are designated the YP 703 class. The general craft characteristics of the YP 703 class emphasize habitability, training areas, hull structure, integrated bridge, maneuverability, propulsion plant configuration, and, for training purposes only, simulated Underway Replenishment. The main and auxiliary systems and electronics are state-of-the art, Commercial-Off-The-Shelf equipment. Design, construction, and selection of systems, sub-systems, and equipment along with associated software are consistent with reduced Total Ownership Cost and shall facilitate system maintenance and periodic upgrades.

The primary mission of the Training Patrol Craft (YP) is to provide the midshipmen professional training course with practical training afloat on a robust platform to conduct professional development in a safe shipboard environment equipped with systems essential to modern seamanship and navigation. Such training is designed to develop within midshipmen the abilities of an Officer-of the Deck, a proficiency in navigation, and a working knowledge of afloat operations.

General Characteristics, YP 676 and YP 696 classes
Primary Function: Training.
Builder: Peterson Builders (YP 676 through 682)
Marinette Marine (YP 683 through 700)
Differences between the YP 676 class and the YP 696 class are only minor configuration changes.
Propulsion: 12V-71N Detroit diesel engines, 2 propellers, horsepower rating 437 shaft horsepower @ 2,100 RPM.
Length: Overall: 108 feet (32.9 meters); Waterline Length: 102 feet (31.1 meters).
Beam: 24 feet (7.3 meters).
Draft: 8 feet (1.9 meters).
Speed: 12 knots (19.6 km/hr).
Range: 1800 nautical miles (3300 km).
Hull Material: Wood hull, aluminum superstructure.
Crew: Officers: 2 Enlisted: 4; Safe Capacity: 50 people.

Gazela under sail

The barkentine, Gazela, was built in the shipyard of J. M. Mendes in Setubal, Portugal. Her records, as she now stands, date from 1901 but there is good evidence that many of the timbers used in her construction are from the ship Gazella (spelled with two Ls) which was built in 1883. Portugese stone pine is the primary wood used in her hull and decks while the masts and spars are of Douglas fir.

What are those furry, caterpillar looking things attached to the rigging called?

For more information on the Gazella and the Jupiter tugboat, both of which belong to the Philadelphia Ship Preservation Guild, visit their website. (No, you won’t find the answer there.)

The Most Boats Win…and So Can You

This past weekend it was Army-Navy game time in Philadelphia. Could it be that Navy won because they brought the most boats?  Philadelphians and out of town visitors got to get up close and personal with 5, yes I said 5, Navy 108 ft YP class boats.  The YP Craft provide realistic, at sea training in navigation and seamanship for midshipmen at the U.S. Naval Academy and officer candidates at Officer Candidate School. YP craft can cruise for up to 1400 nautical miles at 12 knots speed, for a period of five days without refueling or replenishing.

The Army only brought one vessel, the MG Robert Smalls, a 2-year-old, 314 foot long Logistics Support Vessel. The vessel’s namesake ROBERT SMALLS is the first U.S. Army Reserve vessel named for an African-American.  Robert Smalls was born in 1839 on a plantation on Ladies Island, S.C.

Public tours were provided to all the Navy vessels  and the Army vessel before the game.

For a chance to win a Nautical Know How “BoatSafe” tee-shirt, answer the following question.

What does the YP in the YP class Navy vessels stand for?
