Im starting a thread for 2+1 fin setup’s. Searching 2+1 in the archives doesnt really bring up much. I’ve been riding my 7’10’’ a lot lately, and really like the setup in it, which is a 7’’ flexy centre fin, and shapers australia SB sidebites.
.
I have some occy fins that im going to try with an old thruster fin that fits in a LB box.
Im keen to see/hear what size/brand/shape fins everyone uses for their 2+1’s. Any sort of 2+1, short egg, midlength, longboard etc.
Thinking of getting a 6.5’’ centre fin, and using the occ sides with that, to add some manouverability, though im happy with how it goes with the first setup.
I recently made this one, for small days and was hoping that it will noseride . deep single channel in the nose, and 2+1 setup.
I have not ridden it yet but have put some copys of H2 fcs outlines as the side fins and hope to test this setup soon!
I figured smaller side fins (trainer wheels, Ive heard them called) and a big center fin is the traditional setup but looks interesting to try big front fins, let us Know how the board goes with the different setups Beerfan…
SOme nice looking fins and boards guys. I took out the thruster setup this morning in foot overhead punchy beachbreak. Went really well, and released off the top very well. I don’t know if it was the fin setup, or because the waves had some decent punch, but i really liked it. The back of the centre fin is 8’’ from the tail hahaha. Im thinking of even trying some twin fins on the side with the same small centre fin, for smaller stuff. Should be interesting.
I also just recieved a winged keel that bunyip has lent me. Can’t wait to try that as well.
Nocean, what’s the cant on the side bites?> I have a friend who uses the h-2’s on his 9 mal, with a greenough centre fin.
Im now stuck between buying an fcs adaptor, so i can use my fcs fins in in, or buying a 6 1/2’’ centre fin. hmmm. Its fun to experiment with fins!!.
Just so were on the same page , a cutaway fin is a flex fin
heres what I feel is goin on…
A little looser feeling when your compressed in a bottom turn cause the fin flex’s or loads up, then when you end the turn the fin unloads and gives you the momentum or drive that was lost in the bottom turn
you really dont feel the loss in the bottom turn because of all the enertia and momentum, but when the fin springs back you can feel the effect, at least I can
some like it, some dont, and some dont notice it
try this , Longboard with single standard fin, surf it for a few days then try a single flex or cutaway fin of the same size or larger,
I really love the Guy Takyama flex fins they be workin great for me!!!
Thanks mate. I found that a similar thing after i cut the back 1/2’’ of the black fin. It seemed to flex more, and be more responsive, i think going from a fat tip, to a much thinner tip helped. I’ll hunt around the crew and see if i can borrow a cutaway.
beerfan: the h2 copys on my board are standard 5 degree cant but the ones you buy have extra cant like 8 or 9 which might aid turning even more as side fins? not really sure but hope to test board soon!
Im pretty sure they’re more than normal, that’s why i ask. Though i think just the angular shape will make a difference. Ride report please!.
Jusr ordered a 6.5" fin, which should be here tomorrow. I’ll be keen to try the little side bites again, but with the 6.5.
THe thruster setup is definately a great setup for punchy, or hollow waves, where you dont need to obtain as much drive as possible, but for the regular,fat, small stuff, i think the 2+1 suits better. I guess the choice is, more manouverability, or more drive, but with more drawn out turns. Both are good in their own way. It’s great to have choices!!
Great thread! Im in the process of building a 7’0" pill/funboard shape that is 19" x 23.5" x 16.25" with 2" tail rocker and 4 3/4 " of nose rocker that I was thinking of doing a 2 + 1 set u on, Wide …I know… But it works for my 6’7" 255lb frame.
Id love for you guys to share your fin locations for your boxes on the boards posted as well as side bite locations. Cant and toe in would be also be appreciated… I went with a single fin on my last pill that I like but want to really loosen it up and make it a little more high performence.
