Looks Good!!
Yea in salt water it will really be put to the test!! But I am sure that we are not thinking of taking it diving!!
But it will be great on board and you will not have to worry about spray or a wave getting wet.
I bring my Kodak SLR all the time and it is wraped in plastic. I take it out for the fast pic the right back in the plastic! I am always so scared of something happing to it.
I have thought about one of these??
