I have two punctures in the bottom bottom of my board. I won't go into the details of how it happened as it will make me cry There is a perfect 20 knot SE'er and I'm land-bound now. The picture is the worst of the two punctures.

Anyway, is this an easy repair? If so, what materials do I need?
I'm reasonably competent with my hands but know diddly about repairing boards.

Or should I bite the bullet and be without it while I get it done by a professional?
