I've got a midlength board completed to the point I need to add my fin plugs. I want to go quad with thruster option, so 5 boxes. I'm mainly a single fin guy, so not up to speed on either, especially on a board of this size. But this board was made with the intent to break away from single fin addiction, and try something different.
- Board is 8' long by 22" wide
- squash tail is 10"
- 16 3/4" at 12" up
- nose 16" at 12" back
- slight concave in nose blended to flat in middle to V in the tail (slight double concaves through the fin area)
- rails 50-50 in nose, fat down rails (with a tuck) in the middle, hard down in the tail
Any specifics on fin placement would be appreciated!
Also, any fin recommendations appreciated also. Right now I just have the probox quad fins that I ordered with the probox plugs, inexpensive but maybe not best performers? Open to suggestions.
btw, a friend sent me some info, but I didn't grasp it, really. He said
“Fronts at 16", front of box 2.5" from rail, rear of box at 1"
Rears at 8.5", front of box at 3.5", rear of box at 1.75" Fin cant fronts 5 degree rears @ 3 degrees.
Move the rears closer together to produce a feel more like the thruster.
Does this mean the trailing edge of the front fins are at 16" up from the very tail?
I don't get the two measurements off the rail for the box, I need a measurement off the rail for the fin, not the box. Also, I don't want two measurements, I prefer an angle for toe-in, or tell me where in relation to the tip of the board the convergence point is. Which I found in another diagram, saying (I think) fronts converge at 3" in front of nose, rears converge 1.5" in front of nose - I'm pretty sure that's what it said, does that sound right?
Also, where do I put the trailing edge of the rear fin for a thruster setup?
I hope this makes sense, and isn't too repetitive of stuff already posted. I read through all the threads I could find on longboard quads, and even 'tho this isn't a longboard per se, at 8' it is closer to a longboard than a shortboard.
Thanks in advance for any help!
