A dug out canoe? Viking longboat?
Racing always improves the breed and ocean racers stopped using long keels back in the days of Robin K-J. The reason is simple - they have a very poor lift to drag ratio. Absolutely nothing to do with strength of construction since there is no reason why the length of the keel need affect that. Sure Bav cut the corners and paid the price but they would probably do the same with a long keel.
You will carry on believving it's that simple and among those who actually go out there and do it there will continue to be boats with long keels.
