OT: Vintage Racing Boat I saw today

Saw this racing boat hanging up in a ex-machine shop. Needs work, but pretty cool.

here are some pictures. I dont have any history or info on it as the owner wasnt there.

 

I used to race inboard and outboard hydroplanes around Minnesota in the 1970's and 80's. I believe the S cl*** was a 140 ci cl***, using Pinto 4 cylinder engines.It sure was fun. Does anyone know any good web sites? Bill
