V boats sure are pretty

Ridge.
Just out of curiousity what thickness coosa did you use for the floor and hatches.
The balsa in the hatches on the Bertram were rotted so bad it was a mess. I had to use 5/8" to make sure the hatches stay level with the cockpit floor.

I think the key is to do all you can to make sure water never gets to the core, no matter the material...like I KNOW Ridge did...

1/2" for the smaller hatches, 5/8" for the floor and 3/4" for the large deck plate over the fuel tank, IIRC. Knees have 2 layers of 1.5 oz matt sammiched in between two pieces of 3/4" For the hatches I drilled the Coosa and layed it into 2 layers of wet matt before adding weight.
Encapsulated by placing a couple layers of matt on the back of the hatches, two matt and one layer of 24 oz. roven over the floor, about three layers of roven over the knee braces once again layed into matt.

If I had it to do over I would back off the glass/ use 1708 or something similar. I know I am resin rich.

Ridge,
You certainly did over kill. WOW! However you will never have to mess with it again.

Reel,
After speaking with Coosa Composites they said that there is no reason to encapsulate the Coosa board. I did use epoxy and 12oz cloth to encapsulate the mahogany strip that the piano hinged attaches to and a layer in between hatch and Coosa. Hopefully I don't have to repair the hatches again.

From there site..... 45% lighter than plywood, no rot or insect infestation, doesn't not attract mold or fungas, less than 1% water retention, density like plywood

i was thinking of trying nidacore on my hatches a fellow at the local shop uses it and has had good luck with it. he also uses coosa no problems with eather.
