Re: Cvincent's PH18
Working with foam board is certainly new territory for me. When I started planning this project my thoughts were that the composite transom would save on weight, not require overdrill and backfill with epoxy for all penetrations, and of course not rot. One negative aspect I have realized about using foam is that it cost way more due to the additional glass/resin required and weight savings will not be there due to the additional materials required. I also plan to beef up the bracing on the transom interior which will add additional weight. In my opinion both materials wood and foam used for transom construction have their advantages and disadvantages. The use of foam vs wood all boils down to a personal preference in the end.

Re: Cvincent's PH18
What density foam are you using. Coosa 26 lb is what I used. 1.5 inch of coosa with 120oz glass on each side, could hold a 300 LOL!!!

Re: Cvincent's PH18
I am using aqua plas 3 ftom piedmont plastics. According to the mds sheet it has a density of 0.58 to 0.62 gm cm3. Converted to pounds 0.58 x62.43 =36# density. Transom is 2". Wow if 11/2 inch 26# Coosa can support 300hp then I should be ok. Thanks for the info.

Re: Cvincent's PH18
I have been chipping away on the boat. The exterior lamination to the foam transom is done 5 layers of 12oz biax and 5 layers of 10oz weave. The transom is very strong. I also taped the keel and chines. I hope to begin with bottom glass this week.

Re: Cvincent's PH18
The biaxial fiberglass on the bottom and sides is complete. I fastened a temporary dam to the chines and filled with epoxy to make reverse chines. Next will be the fun part, filling and fairing the hull.
