Never heard of a triple step 33 from 85. Did he add the steps? Fountain was one of the earlier adopters and he had some single step boats in the mid 90s.

I just hope the bottom held up, especially with 500hp!!! Redoing a fire damaged boat, and that looked like a massive fire, just didn't make sense to me, he built 95 percent of the boat from scratch, but the 5 percent that he reused was the very bottom. I would think that would be the most important part... Props to the guys for all the work they did though, that was a HUGE project, not trying to be one of the trolls that always goes after me, but wow.

That video was insane. Your work makes so much more sense to me than rebuilding a fire damaged boat, they pretty much started with a keel.

Per the description on Youtube...

Construction of an old 1985 boat that was burnt down in 1997 and was removed from the mangroves by myself and my two son's in March 2015. It was completed on May 12th 2016.

Goes to show anything can be repaired provided you have time, money and a serious stubborn streak by the looks of things.

Well, this week is that week of the year where i take out my 1983 coldmolded Gamefishermen and start poking the bottom to see how bad we beat it up. This year I found a good one! Oh the joys of owning a wood boat! But man it raises fish, and we'll be done in about a week or less so I guess I can't complain, but man this was the worst wet spot I have seen so far...

Here's what it looked like when we took off the layer of glass on the outside:

Bill106 puts this 1700 biaxial kevlar on the bottom of his boats. This is what he prevents...I sure wish I could get that stuff here..

Anyways, so we took out the bad wood and then are opening up each layer a little bit bigger than the last. Tomorrow we will put removable jigs/ribs behind the damages spot and then put some laurel wood in there. This boat has 3 layers at 1/4 inch ish. Today i had to make a trip into the mountains to find a farmer that had laurel in the top of his barn that was dry. Anyway, here is the MASSIVE hole we made in the bottom of the boat today. This thing has a trip next Friday, this is going to be close...

And then while it's out, we are changing out some tubes in the tower. Since we don't have enough to do with the hull. But I'm really happy with how this is looking, the original tube was 1 inch and was always breaking, so I got some nice thick walled 2 inch tube from Western Extrusions in Florida (the only company that will deliver to my freight forwarder) and so we are going back with twice as thick new tubing.

And then we did a little bit of work to the Bertram Hull too. Got most of the fairing done, and then I remember that we took the mold from below the aluminum bumper, so i lost 2.5 inches. So we setup little sticks and we are going to make the mold 2.5 inches taller so it's like the original. Here's a couple pictures of that progress...

And something extra the original didn't have, we are offsetting the hull where the guides go. Should pick up at least .1 knots, right? Either way, smooth is better and it doesn't cost anything extra. I know most boats nowadays do this, but the original did not.

Yeah this is a record. Most years there is no damage, the boat must have knicked the hull the first day out of the shop last year to have this much damage. Not a huge deal, but it is nasty looking! It'll be good as new by Tuesday...

I like how you cut each layer of the core back a little farther to spread out the repair, good thinking.

John W has taken a fishing vacation! He went out to Lake Arenal to try some fresh water. He only got two small fish, but he loves being on the water. Hopefully tomorrow I'll have my wood patch done, and I'll post some pictures!

Here's the hull patch. This is when we cleaned up the hole:



And then we made a frame and did the first two layers together





Here is after the second layer:





And this is after the third layer. The middle layer has opposing grains, and all the layers are stuck down with cabosil/resin mix, and we screw them in with weep holes, and then pull the screws and fill the holes with the same mix.
