Not sure if this has been covered before but can anyone tell me (in layman's terms) what attributes/difference in performance the various tail shapes of surf SUPs (in particular for vanguard style boards) offer e.g.

- round (typically found on non-vanguard style SUPs)
- pin (e.g. Sunova Speeed) more sensitive & helps generate speed?
- square (e.g. Gambler) to pick-up the wave early & offer additional stability?
- fish/swallow/fang (e.g. Minion/Slate/Vbox) to give the board more drive & easier rail-to-rail transition?

Thanks

G'day, just picked up one of these from a friend and it flies, and I can't believe how stable it is (way more than the 8'5" x29"). It's geared up as a quad with 4.7" sides and 4.5" rear fins.

I'll be throwing the old c-drives in to see how they go later today, but also wondering if anyone has been using quads and a nubster on fish-style boards and how they go?

Cheers

Riding my naish hokua 9'10.........have the rear pair of GL sup quad set.
Wondering if any opinions on suitable replacement for the front two fins?
Poor man's way of buying a new board really "use it as a quad"
