I have almost reached the stage of foaming my light weight hull, and was wondering if anyone had tried lining the areas to be foamed with large plastic bags ,( The sort that are used when vacuum bagging small parts) and filling them with expanding foam and sealing them with a bag sealer?
This would keep the water away from the foam altogether and the foam would also give support to the ski without the distortion that occurs when the foam shrinks.
Anther idea was to drill a 3" hole in the bulkhead and fill the complete rear of the ski with polystyrene balls allow to settle / agitate down then force in another 10 or 15 % to ensure they are tight then seal the hole with a cover.
Both these ideas would also use drains in the back.
What do you think , Has it been tried ?
