If you want to save some time and trouble, the one I posted above is for sale.
And as for the crack pics above...I have a repaired hull I rode for the last three seasons that broke the exact same way. It's from multiple beachings and big flat landed flips and rolls. Cerrrrrack!!!!
I added about three layers of 17oz inside and two layers 8 oz on the outside. The boat is now a tank, but it handles awesome and will still take a lickin.
