Welcome to iBoats!!
I'm a sucker for sentimental re-builds.. Take a look at these two links. They should help get you started.
Fabricating Decks, Stringers, and Transoms
Consider yourself one of the lucky ones!!! Your ALL fiberglass stringers are GREAT. As long as they are not delaminated from the hull...You're
GOLDEN!!! This will save you a LOT of time and money. The vinyl insert of the rub rail just pops out (with some persuading from a screwdriver
) and warming it in the sun or using a heat gun on low heat will help too!!! Once it's out drill out the rivets and remove the rail. The cap MIGHT be glued to the hull sides at various points or it may just pop off. NOTE!!!! before doing any demolition, take TONS of Pics and measurements of EVERYTHING. You WILL reference them in the future and be glad you did!!!! Length Width Height at all different points within the boat. Once everything's been removed the hull WILL move around and change shape and you MUST ensure it gets back to the original configuration if you want the cap to fit back on correctly. Especially with that Walk Thru windshield. Have you seen this...

It's about all I could find on your boat. But the good news is,the old tri-hulls are pretty much all the same as far as the way they're put together. Some companies did a better job than others. You'll know more once you get her de-capitated and the deck removed. Right Now get your measurements and pics, buy you PPE and Demo Tools and start tearing her down. The sooner you start...The sooner you'll be on the water.
