Bruce, That's a sweet looking set-up for a quad. I know from your posts that you typically set the fronts about 17'' up with a toe-in of 3/8'' ( in a 4.5 '' fin base ). What's your recommended positioning for the rears . I have been fooling around with adding fins for a quad set-up to some of my Tri's but there are about a million different opinions regarding positioning , toe and cant relative to the front fins. Any guidance with that would be greatly appreciated.
hey Robert.. thx for yr interest and mate, I never have a problem sharing specific information with any genuine query such as yours
Over the past 12-18 months, I have been reducing my base length to 4 1/4" inches (reflecting my use of AM2 railfins) and toeing in 1/4" only (so in effect, the amount of toe has been minimised slightly)
I still set the cant between 6 and 7 degrees off vertical (depending on the amount of spiral thru the bottom contour)
For the secondary railfins in this quadfin setup, I have retained a base length of 4 1/4" but reduced the amount of toe to 1/8"..and this is reflective of its narrower configuration
For Tony, the prinipal railfins are set 17 1/2" from the tail..which is still BEHIND the fin placement on his previous boards (done by a US shaper)..must have been one of those "fins-forward" American shapes
Looking forward to seeing it at huntington

Thanks,
