Mock Up

For expediency, I'm planning on taking this light wind kiteboard I made a while back and installing some mast track boxes to mount the foil. 

Here's the first time I've had these two together.

This board is just over 6' long.  The thickness towards the tail should be enough to drop two reinforcement blocks in.  I'll have to modify the blocks to fit around the finbox already in place, but that shouldn't be too hard.
