Its a home built wood side by side two person boat "modeled after an arrow". It also may be similar to a Gambit. It has no front spring board with a body construction similar to a DN. Dont know any other details as it was built by someone in Colorado many years ago. I would estimate the boat is in the 12 to 13 foot lenght by 8 to 10 foot wide range. Virtually no thought given to safety (similar to most ice boats..). Yes, Im fairly certain its a "uncut" 14 mast.
FYI, if you want to know the real story about ice boat speeds, here is an article from an expert (Bob Dill)
