Strip: Wood Strength
By:Grant Glazer

There has been a fair bit on the forum about the strengths of different cloth layups, but what about the wooden core? Since the strength of a hull comes from fact its a composite would a wood that is harder then Cedar make the composite so much more stronger? Likewise what about a softer wood?

The reason I'm asking is that I'm down to the last 5 strips (on each side) of the hull football area on the Night Heron and would like to use Paulownia instead of WRC in this area. Paulownia is can be compared to a stronger version of Balsa. It dents easily but is flexable and close to the strength of WRC when you break it - measured by the very scientific method of snapping strips :)

I plan to use 2 to 3 layers of 3.25oz cloth in this area. And yes I will be rock gardening and landing on bouldery beaches but my 6oz clothed ply kayak has survived 2yrs of this abuse with out any major scarring so I think I can get away with a lighter hull.

Thanks for your help.
