Grand Banks Keel Repair
On any boat the bottom of the keel is exposed to damage from rocks from cruising in shallow water. We have seen some repairs that were done with putty and paint — far from optimal. There is a cavity in the keel and unless the repair is done right, you will have a keel full of water. This leaves you with a candidate for osmosis (bottom blistering).
We always grind away the affected area back to good glass and rebuild with a fiberglass laminate schedule that is actually more durable than the original, ensuring the problem will not recur if the boat is set on blocks at the repair site during haulout. This is how we find many bad repairs. The weight of the boat will crack the putty as it is point loaded.
