As oppossed to sucking water which would seem be hard on a vaccum especially if the air did not flow through the hull freely how about keeping a positive pressure using a compressor at one end and blowing water out a hole in the transom.

That sounds like it would work as well, Wanabe, and it would probably be easier to regulate so that you don't encourage delaminating. When I used the vacuum I didn't have a compressor or I might have used that instead.

The problem with positive pressure is the fact that the hull is full of foam. You cannot blow air from one end i.e. the pointy end to the transom. It is solid foam or at least should be. Use a vacuum pump, for several hours or even days, you want all the water out, and the foam is hydroscopic to some extent. Bag the area and use heat and vacuum to remove not only water in the cells of the foam but in the foam itself.
