1985 catamaran

Anybody know what this boat is? Current owner does not know.
Laminated wood, built in usa. Located in Tahiti.

 

What is the HIN?

 

It is a homebuilt, no HIN to be found. It used to have inboards, but eventually converted to single outboard. It is a 1989 actually.

 

The hulls look like they could have come out of a mold with possible core. The house definitely looks homebuilt. Is there actual structural wood in the hulls? Is the length about 44'? The massive flair at the bows, straight shear, and bow stem curvature at the waterline, may indicate a certain designer. Did they sail there from a Mexican port? Purchased there? I'm guessing the hull waterline ratio length to width about 15 to 1. Fast if homemade part not overly heavy.

 

Even home built boats get a HIN. Are you sure it is American?

 

Gonzo. Where on a multihull is a HIN usually located?

 

The stern of the starboard hull. It is usually on the stern side of the transom, but occasionally on the side of the hull.

 

I am wondering if there might be some Peter Spronk design influence here?
