Yes it certainly looks build down and a fine form she has. The built down part seems to favor closer to disp speed but the typical straight run of the bottom aft suggests of higher speeds. A flexible hull perhaps. Looks like her fairly narrow beam and apparent displacement (from how much hull is below the WL) suggest that she should be a bit more easily driven than most modern lobster boats. I like her.
Thanks Eric. She is very economical at displacement speeds but I have a heavy hand on the throttle and I pay for it at the pump. She is powered by a 210 hp Cummins 6BT5.9M and will just top 16 knots with a clean bottom and Prop Speed on the prop.
I had a 29.5' Sumner Craft composite express cruiser that weighed 8,000lbs and she went 20 knots w a Ford Lehman. I sure wish I had some good pics of her unusual hull design variations. The engine was inside the keel and the shaft was horizontal. I wish I had her back now. The Sumner Craft was built in Amitiville NY in the 60s. You're in that area .... Ever heard of them?
