Do yall think one layer of 1708 will be enough on the transom, tabbed in with 12" 1708 tape as well.. ? I'm using epoxy for everything, no polyester.

I like the fact you are working from the inside rather than the outside of the transom. Nice job!!

10-4 yea one layer will about the same thickness that came out and it will all be done with epoxy instead of polyester so it will be much stronger.

I cant see how 2,or 3 layers could hurt anything,engine hanging back there going down the road hitting bumps an Potholes. I say more in that area is Better...

It'll eventually hurt a lot more if you don't have sufficient structure there. You've clearly busted your ass to get it to this point. Don't skimp... overdo it.

And on this subject I completely agree but i've already more then surpassed the amount of strength that was originally there and its lasted a HARD 25 years with no problems. The rot issues were from problems with sealing exposed wood from what I can tell. The price of these rebuilds can add up fast when you start doubling everything from what it needs, I will have more in the boat then whats its worth. If I ever sell it I will never be able to explain how I put more then necessary in it and that's why im charging him $2k dollars more.. trust me they would rather have the $2k in their pocket and the boat fall apart from what ive seen.

Bottom line Im planning to keep this one so its gonna be done right but I cant afford to beef up everything on it to the quality of a custom. I appreciate your input just the same though.

Awesome! I just started another thread here with our 1989 C-Hawk 18 restoration.

http://www.thehulltruth.com/boating-...ml#post6130796

Yours looks to be in a bit better shape than mine was/is. I'll be following your thread closely. PM me if you have any questions as you move along. We're up in Apex just outside of Raleigh.

Yep, I know it adds up quick. I guess I just look at it from another perspective: when I was recoring all of my hatches and rehabbing, I did the work with the sole purpose of making it the best it could be for my use, but I never intended to recoup any of those expenses. Excuse the Economics pun, but it's a sunken cost. At the end of the day, market value dictates its worth, regardless of what I've dumped into it.

Either way, you're doing a killer job and I'm looking forward to seeing the finished product. Hope it turns out exactly the way you want it.

No your right, as a general rule overkill is best

trc0806 You would Freak Out if you seen my Deck only. How about 11 layers of cloth? I know its too much,but if you had a Teenager like mine you would understand. He can accidently drop the Anchor on the Deck,an I wouldn't even be concerned. Also I think Epoxy is O K, but according to U S Composites Vinylester Resin is the strongest available @ twice as strong as Epoxy FYI...

Where did you see on US Composites that Vinylester Resin is twice as strong as Epoxy??? I saw where it says its "Similar" to epoxy strength, but not twice as strong.

According to what their "Engineer" told me over the phone Polyester Resin,an Epoxy Resin were 4000/to 7000 #'s tensile breaking strength. Vinyle Ester Resin was rated at 14,000#'s tensil breaking strength... I have their phone number available if anyone needs to Confirm this 1 561 588 1001 I have heard all the Epoxy this ,an Epoxy that,an don't get me wrong I think Epoxy is like the rest of it ,It has places it does BEST.I like the West Systems Epoxy the best of the brands I dealt with.

You like to spend a lot of money don't you?

Most people start with West system and then figure a way to economize.

Like US Composites 2 to 1.

yea I agree west systems is great stuff, probably arguably the best out there but I don't want $25k in my 18' Chawk either.. when I build my Jarrett bay I will use west systems, 11 layer floors and awlgrip paints etc. but till then i'm on realistic budget.
