Thanks guys,

Despite the cautions I think I will still go ahead with it since it is only a small area on the hull. I'm also trying for the lightest yak I can without sacrificing to much strength so am using Paulownia on the sides and deck as well. It also saves ripping another board of Cedar. Of course Murphey always comes along paddling with me and chances are the 1st time I hit a rock it will be there!

For those not familiar with Paulownia, it is an incredible wood. It makes Cedar feel like Jarrah after you have worked with it. It is white with a slight gray shade so it contrasts with Cedar well. Since Paulownia is very fast growing (reaching harvestable stage within 10yrs) there is no grain to speak off. I'm going cove and beadless so can't comment on how well it will take a cove, but because its softer then Cedar it does make very tight joints easy.

Its properties (with Cedar in brackets) are:
Density 240 - 300kg/m3 (380), Modulus of Rapture 40 (54), Modulus of Elasticity 4 (7.2)

Cheers
