I saw your thread on sailnet whilst trying to do some research for my own New Horizon 26. My boat is a 1959 fiberglass hulled 26ft ugly betty. I mean it really is pretty unattractive, however, the price was right for me. I paid 250 dollars for it , but it floats, has no holes, 2 sets of mains and 3 jibs, all in decent shape. I have run into the same problem that you have in terms of finding information about the boat or the company. from what I can tell, the New horizon boat company went out of business sometime in the late sixties or early seventies. In response the the comment you made about the horsepower of the motor, the two other New horizons that I've been able to track down had a 4 cyl Atomic diesel that produces around 30 HP. if you have any more questions or have any info you wouldn't mind sharing with me. please feel free to contact me.
