wing pin single!

Here's board number three. This was supposed to be a 6'7 wingpin single but somehow it grew to 6.9". I experimented with no-glass construction by using marine grade ply for the skins and a bunch of corks to strengthen the inside structure. I almost crushed it vac bagging the top skin on and had to perform some speedy repairs as my glue was setting up. In the end I put in three corks per crossbeam. Its a bit heavier but a lot stronger. The board turned out nearly as light as a fiberglass equivalent. We'll see if it's strong enough. I hand shaped the cedar fin and glued it directly into the board. Still contemplating what oil to use for finishing and my traction options. Here's a link to few more photos.
