From what see, they might need some practice righting the boats, as they always seem to break the mast when doing so.

Maybe send a diver to the mast tip to tie a line whereby they can lift the boat by the mast tip (SLOWLY - to let the water move around the sail) rather than try to jerk the hulls to right the boat.

Or try to right the boat by flipping it over the sterns?

Just seems wierd that they keep breaking the sticks so easily...
