Can a keel boat capsize?
Unlike a dinghy, a keelboat won’t capsize. In a strong wind, it may heel a long way over, but the ballast in its keel is designed to keep it from capsizing. In a dinghy, to resist heeling you would use live ballast – the crew sitting out on the edge of the boat to counter the effect of the wind.
Is the keel heavy?
