Hi Oldboat,

Great boat. We had a 71 IO.

Did you buy or build the hatch receivers? I am debating the make or buy decision because I have not found any that match the dimensions I need.

Best regards,

Ed

I bought both hatchs complete from gulf stream and I am very happy with them. They feel very solid in my 1 inch coosa decks. well worth the cost if u calculate time and materiel to build and another thing done on the forever list.

Got the coosa decks glass down finishing tabbing to start glassing deck surface

Looking good! I'm sure that deck is solid as hell.

Real happy with it.its like a brick even with no glass either side yet. What I found is that the coosa without glass stay really flat and strait so I put a lot of work into getting every thing level so when I glassed in the boards they would align perfectly without putting weight or shims anywhere ,just put my epoxy (mix butter) thick so no gaps and a really nice level deck and just lay them in there. I saw a guy put battery’s and thing on his and it was very wavy uneven. I think I just got lucky for I never did this before.

Cracked open another roll of 1708 (115 pounds) . Starting to cut first layer of 1708. The second layer will go up the side to were grinding stops. Hot out the s morning .

I've never used the coosa without both sides glassed with 1708, however I can't see why it would not be very strong glassed on just the top like you are doing! Since there is less than 1% water absorbstion with the coosa, waht's the difference if the bottom is not glassed?? When you get it tabbed to the sides it will be very strong!!! Good luck!!

I didn't put any glass on the underside of mine either. Solid as a rock! I kept reminding myself of the 2 layers of continuous strand made into the board.

I’m not to worried about it .

Yeah I wouldn't be either. Here is a guy who submerged a scrap piece of Coosa for 5 years. Not a very scientific test, just soaking a scrap piece in tap water, but still has some merit for absorption rates. To quote someone from that thread:

Soaking the complete sheet then would add 7lbs. That's not even one gallon of water.

Personally I would have put a layer of 1708 on the bottom, but only because it would nag at me that I had a chance to over engineer something and didn't. But, that floor is definitely going to outlast all of us, looking great!
