My previous owner grounded very hard. When I bought the boat I ground off the slathered on repair and found the core resin in front of the stub had shattered. Because it was wet and then froze the floor of the head cracked and heaved. I took the stub back to the first keel bolt and then rebuilt it all. I stared with a triangle of 3/4 plywood cut to fit the angle and allowed for 1-1/2" of build up. I then began the tedious job of glassing it, built up into gradually expanding layers until it was roughly the same size as the original stub. This allowed me to bring the glass up the bottom and sidles of the hull to give more strength and help with stresses from unforeseen damage. I think I put 9 yards of glass on her. Faired and finished she's strong, looks like it should and has taken the worst Lake Winnipeg can throw at her while racing. Here's a quick video from the repair 6 years ago. http://youtu.be/kX00wjyGM9M
