I took my twin keel fish out today in knee high, gutless junk. I took the trailing fin out as i thought i wouldn’t need it in tiny waves. Anyway, the board just seemed slow, i mean they were very small and gutless. Anyway, i am curious, i usually ride my board with a 3x3 1/2 ish" trailing fin, which i find adds a bit of stability ( but most of all predictability ), but i also have a g5 centre fin that would fit the trailing fin box. So, my question is, in small gutless waves, would i get more speed/drive by using the g5 in the trailing fin box instead of the smaller trailing fin??, or would that just mean ore drag??.

I’d stick with the smaller fin to reduce drag in small surf. If you only need the trailer for stability, it shouldn’t be an issue in knee high surf.
That’s a trippy looking board. My three cents worth is, that that tail might have been better suited for a single, or trifin set up. Or, that your twin fins are set too far back, and that your swallow tail is not deep enough or wide enough.
With the big single foiled glass on keel fins the board will not release and drive from rail to rail with much center fin in it. Big fins do help in small waves but fin release as critical as fin drive in all surf. When you glass long based fins on the rail of a board you make it hold great but it becomes very difficult to swim the board back and forth to project it. Watch a few films of some high level surfers getting the most out of their keel fin fish and you’ll see that these board trim great, come off the bottom fairly well but as far as engaging them the drive from rail to rail they just don’t cut it. A good horseman would say, "You just cant make an Arabian out of a Morgan.
No Worries, Rich
good question.
might be highly dependent on rider style,
more active athletic style maybe yes,
passive style maybe no
generally speaking,
i think you would have added drive out of more solid bottom turns,
but things might feel a little more draggy on tighter top turns.
nothing beats actual field results…go for it and report back here
i use a smaller center fin in small waves, it creates less drag. i keep the same size sides though.
