Ted Burnell brought me his surf ski one day with an awful hole in it!  If you have any experience with surf skis, you know how fast they are, so it was extremely disturbing to have such a hole.  Any compromise in the exterior of a ski can have a lot of affect on the speed of the vessel.  However, I was able to get the repair faired in and flush with the surface.  Click here to check it out on Facebook.
