How Does one install a AVS fin to a board that doesn't have a box for it.....I've worked with epoxy and fiberglass foam building Airplanes and boats....I assume you cut out a box shape thru the skin and foam and Epoxy the box for the new fin in the space.......or something like that

There is no one that repairs boards in Louisiana....Is there a "how to " site somewhere that shows how to do it??

Mt, It's not that hard especially with your back ground. Call me at the factory 310-530-1383. I will work thru it with you my friend. Mahalo, Larry

I've got to get one of these fitted to my 17...

You'll be glad you did

Hi Larry

is there a formula for deciding the placement of the AVS fin system? Do conditions of area paddling dictate how far forward or back towards the tail one would place the box ??

Yes SEA I do have a formula for AVS fin box placement. There are 2 ways to reach the same result in placement.

1.) If you have a favorite board that you want to retro the AVS set up to then this is the step for that:

  Find the sweet spot of your board where you stand and mark 15 inches forward from your big toe to the back of the Hi Surf 10 1/2" box made by Larry Allison. This will put the AVS box set up in line to your paddle stroke length on that board.

2.) If you are getting a new board never riden by you then this is the measurement process for that:

  Find the BALANCE POINT of the board that you are going to install the AVS set up. Mark from the BALANCE POINT of the board forward 20 inches to the back of the 10 1/2" Hi Surf box made by Larry Allison. This will put you in the saftey Zone placement to adjust your AVS fin to fine tune the board to your liking.


When you use the 2nd install of the AVS Fin Box I already take in to account that 95% of us stand 3 to 5 inches forward of center point of that on any board, verses set up number one to a already know stance on the board being ridden. Important not to get confused and set the AVS Box to far back, because this will cause the AVS FIN to cause reaction with the rear fin.

Nice to see the movement take effect. Remember these comments from others: 1) We already did Front fins years ago like Eaton on prone boards. My answer is you don't get it that placement was further back on a Prone board. 2.) People then compare to Windsurfer Dagger box placement. My answer is that placement is a pivot point which inter fears with the rear fin causing you to go in circles increasing your yaw nightmare to be worse. I have ridden my 14' board with a center fin and reverse the setup like some companies like in the pic below. Makes your 14' turn easy but hard to keep straight even with a rear kick fin. Still playing with this idea but one thing I already know very limited to function just haven't figure out the exact limitations yet with a center box not to get confused with the AVS set up forward of center.

Looks like it's time to get in touch with Larry again. I am considering adding this to my 14' M&M. Thanks for feedback Henrik!

Just wanted to say thanks for being patient my friends. I know some of you have AVS fins on ordr. Didn't forget you, they are being finished this week. Just a few tweaks to fine tune since these are new to the Allison collection. Want to make sure these work to my liking had to spend more water time first before finishing. Hope you Enjoy the ride my friends. Mahalo, Larry
