Re: Mystery boat....
Thanks, oddly enough the soft spot was caused by one of the trailer rollers, I removed the rollers from each side on the trailer to prevent more damage. They were supporting the boat near the bow right where the hull starts to curve in towards the stern. My thought is that this pressure broke the glass in the hull holding the wood/foam in place. From the exterior you see no damage, but if you hit it with your fist it will push in, and you hear wood/foam thump inside against the hull. The boat now sits on four (new) keel rollers, and two bunks at the stern. I would think that is more then enough support for the little boat.
I agree, if there is foam in there, it will most definately be water logged and need replacement. I will know more when winter comes, I'll cut the foam out, check the stringers, re-inforce the hull where it needs it, and possibly refoam the entire thing similar to what some other threads mentioned for the tri-hulls. This has a very flat hull at the bottom, with about a 2-3" gap from the floor to keel. I think using the expanding foam idea would really make this a sturdy little fisher.
I 'think' the original intent for this boat was an early 70's ski boat. Even if I trim the motor out to the point of cavitating when turning it rides fairly nose down. I would imagine a skier would pull that up to plaining level. My neighbor fears the hull may be flexing causing this nose down attitude. I'm gonna get my wife to take some pictures from shore so I can see how it rides on plane.
