Richard, you seem to be a guy that was on top of the boat building industry in your area, any information you can provide on this boat is greatly appreciated.
The keel width is approx. 6' 5", the width at the bottom of the transom bulge is approx 5' 2", at the 2nd set of strakes it's 3 feet and the flat portion is about a foot.
These are just rough measurements taken with a beer in one hand and measuring tape in the other.
One thing I feel worth mentioning is that in the pictures I've found of anacapri boats, there's only 1 or 2 lifting strakes while on this boat there's 3, 2 start at the bow and a 3rd starts about 1/3rd of the way back from the bow high up on the keel, you can barely make it out in this picture, look above the crooked trailer fender, this is the 3rd strake that lines up with the edge of the transom bulge, the 2nd highest strake continues to the back and it about halfway up the keel and the lowest strake continues to the point where the keel is flat on the bottom near the stern.
