Re: Who pays for the food and beer?
When I used to race the serious owners provided travel expenses, hotel and airfare, and yes "ships stores". Captain and Crew raced the boat. Even in local stuff, the owner provided ship's stores if he wanted any kind of crew worth having. Crew throws a big party/dinner at the end of the season for the owner and his family and presents a "gift" like a professional aerial photo of the boat and some gag gifts.
I'd be real disappointed if I busted my tail all day and there wasn't at least a cold beer after tagging and bagging, even after a beer can series.
