Back to the boat that appears in post # 33, 35, and 90 of this thread. She is the 1965 William Garden design originally called Kingfisher. As far as I know, only one boat was built to this design, at one time she was called Joey, and now appears as H.R.B.
Built in Michigan and intended for heavy plank-on-frame wood construction, she is actually heavy fiberglass over a thick strip-planked mahogany plug, left in place. The deck and house are more or less traditional plywood construction with glass sheathing. She's 42' LOA, 39'6" LWL, 14'6" beam, 5'3" draft, and displacement is 57,000 lbs with 10,000 of ballast.
Designed around another(same as Chinook) of the excellent JN-130 Cummins with 4:1 reduction turning a 36" by 27" wheel. In the engine room layout you can see the front of the engine tight against the forward engine room bulkhead. This would be a no-fun setup, way too much service goes on at the front of the engine, and working on it while kneeling in the galley would not be pleasant.
