Originally designed from a modified Yes Thanks for "STAB in the Dark" in 2016. Rusty puffed up the Yes Thanks a little and moved the center point slightly forward. The SD has a deep single concave that zeroes out under the rear fin and finishes with a slight vee in the tail, one smooth curve that accelerates towards the tail. Months after SITD, Rusty's son, Clint, named it the SD. Tweaked it a little a bit with more rocker.
"For the last 5 years it has been one of our most popular designs." - Rusty
SD is offered in Grom, Standard and Pro dimensions featuring the same bottom contour.
