what gear should I bring on a sailing ship?

hi,
I'm going on a schooner for 5 days with a school group, help! I have a 7d, the lenses I have are: 10-22mm 3.5-45 ,50mm 1.8, 17-55mm 2.8, 24-105mmL 4.0,28-135mmmm 3.5-5.6,70-200mmL 2.8 and a 1.4x as well as 2.0x teleconverters and 2 flash units5 in 1 reflector, tripod, monopod, one of those gorillapods a remote flash cable as well as a rf remote transmitter and 2 receivers. I've never even been on of of theses, so any help will be appreciated. thanks

Tom

I'd think about just the 10-22mm & 28-135mm, but the first truth about location shooting is that whatever you leave at home is what you'll want to use the most when you get there.

forget the tripod and monopod, if the boat is rocking they will be useless.

thanks for the replies, I'm following your advice on the 10-22, but going with the 24-105l because the moisture seals, but I'm also throwing the 55-250 kit lens in for good measure
