We have completed testing and have updated all kite racing fin sizes.
Current recommended sized are are trailing fin 3 cm smaller then front fins.
Back fin based back 1 cm.
All fins are made to order so custom sizes are no problem.
Please make sure you let us no if you want the fins bases in different locations in the box.
Also we are going to start offering 2 different base sizes as different manufacturers interpret Tuttle specks differently.
We will be putting detailed instructions on our site on how to fit fins , modify bases for boxes that have under or over sized boxes.
We will be updating our original site meanline.com later in the month.
So menalinefins.com and meanline.com will be duplicate sites.
