Lower 41st Avenue -- the heart of the most vibrant neighborhood in Santa Cruz, CA and home to some of it's best waves. This is the breeding ground of these cutting edge surf and SUP shapes. Kirk McGinty has been building boards under the L41 label since 1996 in Santa Cruz. Work began on the SIMSUP® series in June, 2010. A design engineer by trade and hopeless SUP-junkie, Kirk appreciates the importance of form vs. function. That and his meticulous attention to detail shows through these unique and eye-catching designs.
