This surfboard is the best selling Lost Model of all time. "The every man’s shortboard”  features a low entry and tail rocker into a hyper extended rail rocker in the tail (creating a pronounced vee behind the rear fin), flattish deck, full forgiving outline and rails, with a single to double concave bottom. The SD-II, as known as the Speed Demon surfboard, has evolved into an international favorite for the every day surfer and is one of the most popular surfboard models on the planet.

Also of note, this is our most popular surfboard on both ends of the size spectrum. The design translates well to small mini-grom surfboards like Kolohe Andino’s contest winners (the drivey rocker and full outline forces traditional carving and power surfing into young kids) and also makes a great Big Guy Shortboard in the 6'6" to 7'6"
