Re: what kind of boats are these?
You do realize that with the cost of materials and your labor you would be making less than minimum wage? Restore them if you love to, but not to make money--not unless the hulls are way better than they look in the photos and you can turn them with minimum effort.
Think about it: You need to travel 2 hours and spend time, wear on the tow vehicle and gas, need trailers, the hulls are sitting bow down in the dirt and very likely warped, you need to title or register them before you invest any money or sell them--- AND it is NOT a sure bet to sell an old fiberglass boat. A lot of fuss and bother for a couple of bucks.
NOW: If they were an old hull like a classic wood boat, a Glasspar G3 or Glastron GT150 that has a demand--that's a different story.
All of the above is completely true. Besides, anyone that knows anything about old boats wouldn't want anything to do with those boats if they knew their history. There's a difference between restoring an old boat or just patching up the bad stuff and selling it to someone that don't know what he's getting into.
When I look at an old boat, I look at it as three main points to the hull, outer hull integrity, inner structure and deck, and the transom. A boat needs to have the first and at least one of the the other two for me to even consider bothering with it. And at that, I'd not likely do any major rebuild work on any run of the mill old hull. It would have to be a boat I really liked and intended to keep forever. You will NEVER recover your time, labor, and materials and any sort of profit from a project like those. When I'm working, they pay me good money, if I'm going to work during my free time, I need to make at least as much as when I'm at work or more for me to give up my time. Therefore there's no way there could be enough room for a decent profit in an old boat considering all the man hours needed to do fiberglass and wood work, plus the cost of materials and any further work needed to get the engines in shape or replaced.
When I see a boat that's been sitting bow down for any length of time collecting rain, it's the same to me as a boat that's been sunk. The damage may not be immediate or visible but it's there.
I've got a neighbor that decided that he wanted to have the deck and transom replaced on his Welcraft. He took it to a local marina that is known for that sort of work. He was quoted only that the average job like that runs in excess of $5500, and that they charge hourly. When the boat was done, it looked good, but he was handed a bill for $7200. Far more than I figured his boat was worth. If it were mine, I'd have put that $7200 into a better hull. The way I see it is that he's got a boat that he spent $6600 to buy, and has another $7200 in the deck, stringers, and transom, plus another $9,000 in the motor. He could have bought a newer, nicer boat for half of that. After all that money, he's still got a 35 year old boat with other issues that crop up all the time. This year he's buying a new aluminum tandem trailer for $4500. Worse yet, it's all on a credit card.
At least all of my boats are paid for and I do my own work all around. I don't mind helping out a friend but his boat wouldn't fit in my garage, and he insisted on getting it done in February.
If your insistant on rebuilding an old boat, find something that's worth redoing, I don't see anything special about those two old hulks. Even in perfect shape I'd be surprised if they would bring over a 5 or $600. Your going to have far more than that in labor let alone materials.
