I just put my Hobie 17 (1985) away for the winter (Southern Illinois) and noticed cracks in 3 of the 4wing support holes in the hull. The cracks are both vertical and horizontal but are predominat in the middle. There is about an inch of water at the bottom of each support hole so the bottom appears to be solid.

My question is how do you repair the cracks? Perhaps a better question is repairs need to be made if the bottom appear to in one solid piece.

Appreciate any suggestions or recommendations.

Joe
