Re: Here we goooo!!!!!
Well I am going to say this. The amount of resin and glass you use is going to be the biggest part of your cost. For a 19 foot boat, 15 gallons of resin would seem to indicate that the boat had many layers of heavy glass put down on everything. A boat done this way will likely outlast the owner, and if not the interior and the mechanicals will be shot before the wood every fails (with proper care of course.)
I'd say expect to spend 300.00 on wood
another 4-500 on resin and glass
300 more on 2 part foam if you are going to use it
and who knows what you will spend on hardware and such as you go. I replaced a bow eye tonight on my project and that alone was 13 bucks plus a dab of 5200 (at 7 bucks for a 3 ounce tube) I am on my 3rd tube now.
I used 12-15 large tubes of PL premium adhesive during the project at about 7 dollars a piece
Stainless hardware was another 50-60 bucks by the time I was done and just buying wires, connectors switches and breakers really added up.
I'd say if you can reuse a lot of the hardware and use a reasonable glass layup plan, you could do it for $1200-1500.00.
I am just getting close to finishing a 19 foot ski boat and almost every trip to the store costs $100 bucks or more.
I used epoxy and 10 oz cloth with 3 layers on the stringers and transom, 2 on the seams and deck tabbing 2 coats on each side of all decking and I have a roll of lighter cloth for the final deck covering. All in all, I think I'll finish up with under 7 gallons. My wood may rot in 15-20 years, but if it lasted 20 years before I got it with wood that was not coated as well and with materials that were inferior, I think I'll get all the life out of it I need.
I made it a point to find out where the failures were that caused my boat to be in such bad shape and it was poor maintenance, shoddy mechanical repairs, and improper storage that started the rot. Then it was sistering in 2x4's to the stringers , adding cross braces, cutting into the glass, and not sealing or glassing anything that drove in the coffin nails.
Why did your boat rot? Until you can answer this question, a rebuild should wait. If there was a cause and you don't identify it, you risk repeating it. No matter what you use or how you do it, water will wick through just about anything with enough time on it's hands.
