…Lost designed the Kingfish to be ridden about 6" longer, on average, than you would ride the RNF ’96; you can go shorter on the small sizes and longer on the larger ones. For example, if you ride a 5’6 RNF ’96, start around the 6’0 (20.00" x 2.50", 34.00 L). Stock sizes run from 5’10 (19.75" x 2.45", 32.00 L) to 7’6 (22.00" x 2.96", 55.00 L). If you don’t know your volume, use the Volume calculator at the top of our …Lost 3D board builder: enter your height, weight, skill, fitness and the waves you surf, and it recommends a volume by board type, from shortboard to fish, hybrid and mid-length. Our shop staff can help you pick a size.

Futures doesn’t list the Kingfish; for the RNF ’96 it is stretched from, which uses the same 2+1 setup, Futures recommends the Mayhem Evil Twin+1 (Medium, Large), the Rasta Twin+1 (a more upright twin) or the Mark Richards Twin+1.
