I have had my board for a little over a year. Love it. However, for whatever reason, the fin has now fallen out twice. And yes, I know that the pin goes in, has to snap, etc.
I ordered the replacement fin after having the board sit in my garage all winter (put it away after the fin fell out last year). Took it out ONCE on Lake Granby and the new fin was gone forever. I will get another one, but if it too falls out I am gonna give up on this board and go with something else. I hate to because this is the best board I have ever had and I have had about a dozen. The fact that I can get this type of ride out of an inflatable is a miracle.
