.......for those who ask that kind of a question.....um....lets just say that whenever I am out sailing (Galveston, Texas or any one of the Texas' area lakes) & someone attempts to "use the facilities," um......we just happen to 'find' a way to luff the sails!!

=

(I "just don't know who did that!") ....is usually the response we give (when they get back onboard) when the lifejacketed individual is seen yelling as they tumble out of the boat
ok....now for the serious comment -----there are none. you are on a sailboat. Moreover, a 12-metre boat is big & all eyes need to be on what you are doing; be it for real or what not as getting hit with the boom or losing a wench handle is something you don't want to have happen to you (just a kind suggestion).
P.S. WE NEED TO WIN THE AMERICA'S CUP!!!! GO SF YACHT CLUB.
