Post a few photos and maybe someone will recognize it's make. Aluminum Trihulls are rare..... very rare.... I do not think I have seen one now that I think about it. Post the pictures.
I have no idea but I will keep looking. Are the seams welded? Being an "older" boat I would be concerned about the floatation being water logged which would add weight.
What is the deck made of? Is it aluminum or wood?
Would love to see some more photos of the transom under the splashwell.
Wanna sell it? Just kidding...sorta. Many work boats of that era were built by independant boat yards, typically building larger boats. Often a customer would request a one-of smaller boat which had a specific purpose. I'm guessing it's a custom build.
