Is it me or do those fin boxes look really far up from tail…You are gonna need a really rakey, which i do not like, fin to make that thing “work”. My best guess. 105lb girlfriend how long is the board?
neat name....never heard of him. Post photos of rider....ha ha.
What fin should I use is sort of like what car should I drive...............too many answers. And you did not say single or 2+1....... a standard California Classic fin is a nice place to start about 8-9 inches for that board.....but I weigh 80 pounds more than your rider.....and I have a stink bug style, wear booties in the summer, my board has 100% astro deck, ect.........................
I think 9’ is too much board for 105 lbs… The thing about fins (single), is that the more experience you have as a surfer, the more you will be sensitive to different fins (length, profile, rake, flex, etc.). For a beginner, it doesn’t matter too much. But, what IS important (and what many beginners have no clue about) is fin placement. Start moving fin forward in the box a little bit each session until the board becomes too loose. Too loose means it starts to get twitchy, squirrelly and unpredictable. You will know - you’ll find the board flopping/bouncing around too much . Move the fin back a bit until things settle down, but yet still responsive. Every time you try a new fin you have to find it’s particular sweet spot. Every fin is different. You will not really know what a particular fin is all about until you find it’s ideal placement.
