The fact is that some things just disappear and no one knows where they go. There must be a stash of single socks and gloves somewhere in the heavens.

The same thing happens over time on your boat. So the winter season is a good time to check your onboard tool kit and spare parts to make sure none of those have disappeared into sock and glove heaven. That will give you time to replace what’s missing before your spring boating debut.

Every vessel should have a basic mechanic’s tool kit onboard. This kit should include, at minimum, the following:


  • Socket set – 3/8 drive (3/8″ – 13/16″)
  • Open and box wrenches (3/16″ – 1″)
  • Screw driver set – slotted & Phillips
