Thanks everyone! It feels really good to get this started!
Yes, I know that this Pantera got some good ol' beating in it's past. Looks like someone has been trying to repair something around the stringer before, anyhow it will be properly done now.
I will try to remember to do that the next time I'm at the boat.
Yup, the fuel tank it located between the stringers but on those pics I have removed it to be able to fix the stringer and the bottom that had some delamination.
The crack started where the stringer it cut down to lower the cockpit floor to about one inch lower than standard. Pantera did this and put the lower fuel tank in to lower the centre of gravity, to get better riding stability.
Here are a before and two after pics, the bottom and both stringers will be strengthened and then the fuel tank will be put back with foam as before or perhaps we will use divinycell or bonocell or similar.

The boat is looking good, where is your fuel tank located? I thought it would be in the pictured area between the stringers.

Also got started with the carbs today and deassambled them and put them in a container with gasoline until tomorrow when I will start cleaning everything and replacing all parts that are exposed to wear.

I'm going to leave it as is, put in the tank and either fill the space between the hull with foam or put in sheets of high density foam material.

Tomas, you make me feel good because mine is less ripped apart than yours right now.
That is an awesome tower of power, wish that would fit under my hatch.

Nah, it's really no biggie putting it back together when the repair is done. We're going to strengthen the floor as well but of course still keep the weight down.

I'm With ya on the weight thing, Pulled out over 100lbs of cabin liner and stuff and replacing it with new stuff at about 25 lbs total. Not much but it does add up.

The rear part of the floor was actually made out of glassed .3-.4" thick plywood, and the rest of, perhaps, divinycell or similar. The plywood will be replaced with some sort of high density foam and the whole floor will be glassed with a layer or two of thin glassfiber sheets.
The welds that fixate the brackets that hold the fuel tank had come loose so that will be redone as well, that has probably something to do with the damage...
Altough, that's an easy fix - will take care of that when we replace the fuel pickup with a bigger one.

How much overdrive do I really need to get 8-10psi boost with a BDS 8-71/509/wot@5700rpm? Right now the pulleys are 52 (lower) and 60 (upper), that gives me a 13.3% underdrive? We didn't have a boost gauge last season but did measure the boost once and got .4bars = 5.8psi. But that gauge was absolutely not the most trustworthy one...
