Hey,
Well, in the off season there is always this exercise called 'maintenance'
I 'work out' by
-holding a sander against the hull in all sorts of strange positions. You get to stretch to reach parts of the boat that are forward, crouch to sand other parts and crawl to do the keel. It's a great workout.
-When the sanding is done my next 'work out' routine is to move a paint roller back and forth, back and forth, back and forth. This is great for strength, balance, flexibility and stamina. Sometime I like this so much that I do two coats of paint. This is twice the workout!
To really work on my flexibility I like to crawl into the tight spaces on my boat. Things like lazaretts, engine compartments, and inside lockers. To add some strength training I will occasionally pull wires or hoses from one end of the boat to the other.
To work on my coordination I wax and polish the boat. You need to move the polish rag in multiple directions. For a real challenge try using a rag in each hand!
My next routine is done when the boat gets splashed. For speed and flexibility I do the 'leak test'. The marina drops the boat in the water and I run around the inside as fast as I can opening up lockers and crawling into tight spaces looking for signs of water. Try it - it's great fun. Next up come strength and balance exercises: First is the Boom Lift where you move a 100 lb 12' aluminum bar from inside the boat to outside the boat. You get to balance the boom while trying to attach it to a great piece of fitness gear called the 'goose neck'. Next up is the Sail Bend where you move a 100lb sail from basement to car to boat to mast. I like this one so much that I do it twice. The second time is even more fun because the 'headsail' is bigger and heavier than the mainsail.
Once the boat is all ready for sailing I keep fit by 'rowing' to the boat, pulling on all sorts of ropes, and staying hydrated!
