I just bought a 2019 Freewave STB 105 for sailing here in SF Bay. It came with a Starfish 30cm Choco fin (standard), but I think I may need a smaller fin for those days where I don't need to point as much (ebb tide at the Delta) and with smaller sails (less than 4.8m). What size / type would you recommend? Thanks.
, Hi there, have a look at the archive for 2019 for the TE version of the FW, then you can see what Trifin options there are.
As as a smaller singe fin, go for a similar style of the Starfish in size 25/26?
As Craig suggested, lots of info already available here. Check this thread out in particular, from about 17 days ago: https://forum.fanatic.com/d/26905-fin-setup-for-fanatic-stb-to-prevent-spin-out
You'll find some good advice there from Guyt54 and Mark4308.
