    Used roughly 14 gallons of West Systems 5:1 Epoxy for the entire build. Transom, gunwales and combings are all 4 layers of 8oz E-glass cloth. Deck is single layer of 32oz woven roving.

    Layed in two layers of glass and the first piece of of 3/4" coosa board. Going to bond the next two layers later this week and glass it all in this weekend. I think I went a bit light on epoxy and didnt get the squeeze out I was looking for. I think it should be good enough we got it clamped in there pretty solid

    That means you have voids where there is no bond.

    Yeah I know I think it may have a few small voids but nothing substantial. Will have a better idea once its cured but too late now either way

    If it’s not too cured yet you could send a few screws on washers through the outer skin into Coosa and pull them together a bit more. Start at the bottom and work up.

    Yeah I would have predrilled holes for bolts. Like 30 of them and fill in later and paint. That's some crazy clamping you got there

    Did you ever ponder the idea of widening the stern of the hull to add room, flotation, stability? It looks like a pinched stern like my harris is. Wondering if anyone was crazy enough to think about it like I want to do on my rebuild

    got all 3 layers of 3/4" bonded, plenty of squeeze out this time. I used way more screws this time and it did the trick. Once I drill the holes for the bracket I can see how the first bond is and either leave it or grind the back off and try this again haha. Glass on saturday should wrap up the transom and onto the stringers

    So that transom is 1000$ of coosa?

    its about $225 a sheet of 4x8 and I will be using the leftover pieces to do the rails, the stuff is not cheap but it is an awesome material

    I think I would leave it alone and glass it. My guess is you won't be able to get it back off without destroying all the coosa.

    A more practical approach might be to drill a pattern of small holes, on a grid, and inject epoxy into the voids. However this is best done before the original epoxy has fully cured.

    Did you end up layering in more glass in the hull bilge??

    I haven't and am not sure it really needs it, once I get more structure replaced I will see how solid she is. Can you school me on lifting/spray rails for this boat? I read what you wrote in the "Eastporters built new thread" and am wondering if you have any pictures or a sketch of the keel you are talking about.

    Got 4 layers of 17oz on the transom. Was planning on 5 or 6 but ran out of time last night. Plan is to tab in the stringers and add another layer or two on the transom at the same time. I may give the outside of the transom a layer of 10z once I have it all the holes filled. Learning a ton so far I wish I started on something less important than the transom but I think overall it went very well. Running out of time to decide on a motor. It seems like a 20" shaft would be ideal for this boat with the bracket, anyone disagree? I have sen a 25" and it seems to work great as well. Have a line on a yammy 150 25" with 100 hours, seems like a bit more power than needed but I think the extra weight shouldn't be too big of a problem. Ideal setup would probably be a zuke 140 or a 110. Really looking for opinions here so feel free, thanks! IMG_2198.jpg IMG_2200.jpg IMG_2201.jpg

    Bracket would be best option- second best is notch for a 25" leg- I wouldn't go with the 20" transom as you may have to trim it down even more and water may come into the boat if you get a big following sea swell.

    I am doing a bracket for sure, are you saying a 20" for that would be best option?

    That all depends on your bracket height. But definitely a bracket. More room.

    Bracket will be custom so height will be dependent on the shaft length so I am leaning towards the 20" to keep the bracket lower
