I bring Subway samiches, fresh fruit, and water for my J22 crew for Saturday club races. You probably wouldn't care for my beer rule though. Beer happens only after the boat is put away after racing for two reasons. A) the boat is tidied up, secured in the slip, and the deck tent snapped on REALLY fast after racing. B) that first beer after all of that is sooo good.
A rule I could easily live with. Subway would be huge step up from air sandwiches. :-)
