James,
HTV or Halbrehder Tunnel Vee's came about in 1981. Built a 13' full size tunnel vee that we ran with a 75 Evinrude. The model versions are just plain HTV's and I don't use animal or agressive names. Now if you have one of my boats it would have to be pretty old as I do not sell boats. I did back in the old days but just not worth my time and aggrivation anymore. I currently build hulls for a few serious racers and the agreement is that the boat be returned if not used and never to be sold. The old "duck bill" cowl was updated last spring and does hold the nose down better. Send me a pic of the bottom of what you have and I can identify it. My boats aren't pretty but have a good record in heat racing.

Well Mic I am being an antagonist like usual, sorta. Joking around about the name, although I was curious if you had a model name for them, seems all hulls have a name. Come on man, make it offical and go with "Dolphin Head"!! Reality is I do have one, or a copy, or a want to be HTV, or someone broke the vow. There is no doubt that the cowling is HTV design, and the hull sponson design matches the description you gave me a while back. I have no intentions of selling it, I am certainly impressed with the performance of yours and the #1 sons boats. I will outfit it this winter and see what happens. Even if it is not a genuine HTV it will still be fun to try it out. It is Gray and White and has a Coca-Cola paint scheme on it. See ya at the World Champs next spring. James
