I would use glass in the bait well for sure.
As for foam - I'm an active duty coastie...I know all too well about all of that stuff!

My pleasure!

I'll keep you guys posted on my progress. Not sure when I will make the order, looks like about $500 worth of goodies.

Thanks again!

sorry I missed this one until now. i will take the original questions one at a time, but Cl has already make recommendations that will work very well.
I need some help on how to wrap and attach my new decks
It looks like you have some fir there to make your parts. I would cover all the surfaces of that wood with a 10 woven cloth, its inexpensive and it will keep the wood grain from checking and also give good abrasion resistance.
Now, how should I wrap the decks and bulkheads, and how should I glass them to the hull sides, transom, and deck?
tabbing the new parts into the hull should be done with 12 oz biax tape. That rear box/casing deck should get two layers of the tabbing.

grind back the gelcoat anywhere you will be glassing part - new glass has to be made to the old glass, not on top of the glecoat
Hull sides are 14" tall with a 1.5" radius rolled edge (this us where I want to add glass to the sides to stiffen it up)
to stiffen up the sides, adding glass will not do a lot by itself, you need to create a shape that will stiffen it. Gunnels would certainly do the trick, but thats a lot of work.

One very easy (and in expensive) way to add a lot of stiffness would be to glass a half round piece of PVC pipe to the sides, right below the sheer. You cut the pipe in half length wise, then glass it to the sides, overlapping the top and bottom of the hull sides. PVC can be a very light gauge. You dont need much glass, a couple layers of 12 oz biax or one layer 1708 is more than enough. The PVC doubles as good place to run wires.

The suggested BOM CL made is a good one. I would only add a bag of silica (add to woodflour to make fillets), and you can use 12 oz biax or the 10 woven for covering the wood. the 12 oz biax takes turns much nicer, but the 10 oz takes less fairing (not by much) and its a bit cheaper.

Sorry again that I missed the thread until now

Thanks Shine!

I'll play with the hull sides and see how much more stiffening the rolled edge needs. The factory rolled edge is plenty strong. There are just a few areas where there was some 'dock crashing' done, and it weakened the rolled edge. I am mainly looking to fix/stiffen these areas, not necessarily the whole rolled edge. I don't plan on crashing it into my dock, so more rigidity shouldnt be needed. Mainly just repairing it back to the way it was originally.

In regards to the fairing on the different cloths: I plan to durabak all of the areas that will have work done on them (except the inside of the baitwell). So, I'm not too worried about fairing a whole lot. Some of the finishes you guys achieve with fairing/painting are amazing. Luckily, this boat doesn't need to meet those standards because it would take me forever to get there!

Thanks again,
Shawn

Quick question; how much 'flash' time is minimum for in between coats of epoxy?

For instance: If I am taping/filleting joints on the bulkheads/frames, how long do I need to let them set before I apply a complete coat over the bare wood?

I'm trying to gauge how much time I will need to do all of the glass work once everything is laid out. I know if I let anything sit too long I will have to sand. But, can you let it sit 'too short' and mess it up by applying over top of it too soon?

Thanks,
Shawn

No, no flash time required between coats, as fast as you can work is fine.
