AVS calculations for drop keel boats are made with the assumption that the keel will stay put. I have come across quite a few that rely on gravity to keep the keel down. Once the boat goes beyond a 90° knock-down the keel is able to retract, reducing stability at a critical point. Coded boats with drop keels have to have a positive lock in the down position but plenty of ordinary cruisers don't.no its not , because its quicker to drop a keel
