Since I built my Kevlar Pearl in 2015, I've built two more Composite solos.
In Both of these I used a cedar strip insert.
My last ( Black Pearl). I cut the strips for the insert at 1/8". This was quite a weight savings. The hull is 16' long, and weighs in at 36 1/2 #.
This is going to get a lot of water time, and a shot at the BWCA this Fall.
Here's some pics. I also included Vader, a Kevlar/ Carbon copy of my Nokomis. 16' 4" .
First Vader, and Nokomis the stripper I used as the mold.
Finally Black Pearl
