Shark gets a fin

Here is the new 9inch fin we just installed on our carbon board.

We finished our first carbon fiber 12 foot Sea State board today.
It is actually half carbon.  The hull is carbon and epoxy and the deck is gel-coated glass set in resin.
A carbon finished deck would be too hot to deal with.
To wrap things up with this board, we added a 9 inch fin.  Here are photos that show how a standard fin box accepts a fin.

Our fin boxes are laminated into the hull and we find and cut them open after the hull is molded.  Once it is cleaned up, the fin attached easily...

The new fin, fin bolt and regular screw driver sit next to the just opened fin box.

This is how the bolt slides into the channel.

Next, the fin slides into the channel toward the front of the box.

You tap the fin forward with the palm of your hand or a rubber mallet.

Next, the bolt screws into the pre-inserted nut and voila, it is done.
