Hi all



My craft has a drain hole from the plenum to the outside of the craft and a drain hole from the inside of the craft into the plenum.



Its an upper and lower hull with 4 inches of boyancy in between.



When I got the craft it had an inflatable bag just behind the fan in the plenum. This was obviously for flotation as the back of the craft must be too heavy but then again it would be with it filling up through the drain hole to the outside.



I have blocked up both drain holes with plugs which I can remove if necessary.



Is this the right thing to do.



Thanks in advance



Pat
