I have fixed up a 24' sailboat from a minor wreck, including re-fairing the keel, replacing the rudder, replacing keel bolts, and reinforcing the transom. I also installed a fish finder/depth gauge, bilge pump, stereo, scat box for pump out, interior and running lights. Then I sailed it for about ten years.
I recently made a surfboard for my daughter. I have many skills in the trades, including carpentry, metal fabrication, fiberglass, rigging, some plumbing, some electrical. Although, many of my tools are still up north.
I have done and can do many things on a boat.
If you need crew, I play guitar and know a few sea shanties.
