Default Re: Coosa

I used it on my 25' for the knees and inside the console. Like the other have said it was very easy to work with.

If I was going to put screws into it I would drill the larger hole and fill it with glass then re-drill for the screw. I can't recall where I seen that info.....it might have been in the West Systems booklet.

I e-mailed Coosa today and they were happy to send out a product sample.
Not bad if anyone is interested in using the stuff.

Scott,

You are correct "Yikes". That is what I said plus a few other choice words. I have removed all of the wood from the boat and will or have used coosa for the transom, deck, cap,
hatches , everything where a core is needed.Also, I replaced the fuel tank and used a piece of 3/4"coosa for the fuel tank bed( 8'L x 28" w).The console is going to be stiffened with 1/2" coosa because I am having a hard top frame fabricated which will be mounted to the console rather than screwed into the deck. It doesn't take long before material usage mounts up. Basically 25% of the cost
of the coosa is in the transom alone.

Although I have never used the stuff I really like it based on so many guys which have and told me so. But it sure does cost $$. The biggest concerns on SeaCrafts is the transom area due to it needing to be strong, light, and rot free. If money is a issue you could just do the Transom with it, then use other materials for the rest of the boat where weight and strength and rot free is not as much of a issue. I personally really like a heavy boat for the ride but with a 8’ beams boat “lighter is better” in the transom and 30% lighter that wood sounds really good to me.

Couple of thoughts/questions,

Does the Coosa board actually absorb epoxy like a wood core does?

How much weight does the plywood core in a transom actually add over a coosa cored transom?

No the epoxy doesn't go into Coosa like plywood. Remember a tree has pores in it.


Plywood is almost double the weight.

What does it cost for enough Coosa to do a transom on a SeaCraft 20?
A local plywood dealer has 4'x8', 3/4 A/B doug fir marine for $80 sheet. Lets say a transom will take about 70% of each sheet, so the ply for that transom will weigh about 105#'s and cost about $160. If Coosa weighs about 1/2 as much as the ply, what's the cost premium to save about 50#'s?

Yes it weighs less, but the major benefit is the fact that it will not absorb water warp or rot. Spend the money now or spend it later...........

Don ...Have you done anything with thus stuff?

Dan .. a 4 x 8 1.5" sheet of the Bluewater 26 ( I guess he heaviest they make ) is a 104 lbs ... The sheet is $563 picked up ... a 5 hour trip for me personally.

The info I have states it is (Bluewater 26) 30% lighter than plywood
The slightly less dense Bluewater 20 Claims 45%
