As a side point... whenever I'd go sailing or land based in the islands, I'd bring a couple clean, fluffy, but slightly old towels. At the end of the trip, when they are heavier, dirtier (even if washed), I would leave them behind - thus, having some spare space and weight allowance in my bag for the return trip.

I figure a bottle of rum or two might be a better use of my baggage space. <img src="http://www.traveltalkonline.com/forums/images/graemlins/Grin.gif" alt="" />
