Rob, two things if you please.

70 sqmeters of kiri equates to 762 square feet which is a real savings
on materials for a cat or tri in the 25 to 28 foot range. Is this for
real? plus maybe the ply under the bunks i.e. bridge deck bottom for
another 100 sqft of so?

Does the 400 gsm equate to about 13 oz per yard???

Thanks Bob G.
