One year during cowes week we were having breakfast at a café and the crew of a 1/2 tonner on the next table were animatedly discussing how they could cut the weight of their boat. As they ran through all the things they could jettison/drill holes in, our skipper leant over, pointed at one of their number and helpfully suggested "Why don't you just get rid of fatso there". Their was a brief silence before the reply came "er......it's his boat".
In fact our skipper was wrong - on boats like that moveable ballast is usually a good thing (up to a point). It's the immobile variety one can do without.
