Well as a lot of windsurfers and surfers might be, I'm thinking of starting the new year with a new board (or two). I'm thinking that the first will be a floaty low wind wave board in eps200 foam with a poplar veneer sandwich deck, and recycled boxes, inserts etc, pretty straightforward. I'm also thinking of a better conditions-orientated wave board, which i'm thinking of doing in lighter weight foam, (depending on the final weight of the light wind one), with Poplar (tulipwood) veneer sandwich top and bottom, with cork rails, and setup as a bonzer 5..... (can also be a single if the side fins screw it up)..... So, a couple of uncertainties with the second one. 1. I figure to build up the rails, i will need several layers of cork, and should they be glued/epoxied/glassed together? and then glassed over the top? and will the cork provide enough stiffness? 2. fin angles, On surfboards, obviously the toe in is way more than windsurfers, so i'm thinking i should set them about 2 degrees? and 15 degrees cant as the Campbell brothers (and Berndt Roedinger) set theirs. I'd like a few opinions.... Ps Happy new year!
eps200? what's that? for superlight stuff I use 13kg/m3, for my wave boards I used 24kg/m3 but now I think that was overkill, for my weight anyway
Is it an oz weight ?
As in oz , ounce or some other unit of measure ???
I have a nice expensive block of 19 kg for my next board .
19 is nice to shape.
Have I ever mentioned , never to glue slabs of foam together to save money ?

eps 70 is the lightweight core for most production boards, 200 is much denser, so i can get away with lighter glassing i hope!

I think the eps 200 is 30kg/m3, which is probably way over the top!
30 is OK for your core plus wood laminate but would be easy to accidentally make it too heavy.
If capable of vac bagging just go a tiny bit more difficult and do divinycell / corecell over 13-15kg EPS?

As i have the 30, I'll give it a go and expect it to be heavier than ideal. I did a test piece with it and a 4oz/bamboo/6 oz laminate, and it was pretty indestructible, then realised i could have gone lighter with the foam! Next time......
