I've always like the Drascombe Scaffie for it's simplicity, a perfect boat for pottering around the harbours and estuaries and while I'm not normally really taken by double ender's, the Scaffie is undeniably pretty. The lack of a centreboard, and the associated space of the case and restrictions to the cockpit are good features, but presumably the trade off is lack of pointing ability.
The original Drascombe Lugger is also a handsome boat, bigger and heavier to handle ashore than the Scaffie. The drop through rudder demands care in very shallow waters, at least compared to a transom mounted lifting rudder.
Overall two fine boats, ideal for getting out on inshore waters.
Too many boats, too little time.
