I've got the envious problem (i suppose) of having #551 come out a bit light. With a small 4.8V battery pack the boat weighed around 13lbs8oz. Minimum all up weight per the class rules is 14lbs5oz.

My first step was to switch over to a big 7.2V 4200 nimh battery pack. This fits nicely in the keel sump as low as possible in the boat. Had to switch out the rudder servo to a Hitec 5087 high voltage servo to match the 7950 I'm using for the sails. Nice thing is I think I can sail the boat non-stop all day (and then some) with this battery.

Also added 3.2oz of lead shot in a small zip-bag in the keel sump.

Ed Crowell was nice enough to let me borrow his super-sensitive, super accurate check-out scale, which reads 14.32lbs. (converts to 14lbs5.12oz).

My slightly less accurate (and less sensitive) postal scale reads 14lbs5.5oz.

I think that's close enough!!! Thanks again to Ed Crowell for all his help and support!!!
