I like to sail and my 13 yr old son loves paintball, So...........

Boat crews are armed with paintball guns, when all crew members are
shot, game is over. A shot member cannot shoot anymore or help sail.

That might be fun, although Martin comments about the impact of
paintball on bare skin is something to consider... also the cleaning of
the boats afterwards.

Some years ago, a sailing club I was in experimented with all sorts of
sailing based games, including Phil Bolger's pirate game (which was
pretty cool), but also using soccer & basketballs. The best game
involved using 1 ball for every 2 or 3 boats, and a set of rules which
was not too complicated but involved scoring by bringing a ball into a
windward goal, without carrying the ball on board the boat for more than
a few seconds at a time. This resulted in a lot of close quarters
maneuvering drill and improved boat handling skills dramatically.
