Based on our most popular River SUP board, the C-MAC ATB 10-6, the 10-6 ATB iSUP inflatable stand-up board is our largest inflatable. C-MAC stands for Charlie MacArthur, our river sup expert, and ATB stands for All-Terrain-Board.

Clean lines and proven performance make this Dave Parmenter shaped 9'6" foot wing swallow the perfect board for stand up surfing. The BoardWorks TEC construction makes this board light and strong. Comes with five boxes to run thruster, 2 x 1 or quad fin set up.

Based on Dave Parmenter's proven Stub Vector, the Sub-Vector is the perfect short board for stand-up paddle surfing.

Dave Parmenter and Brian Keaulana need no introduction: Dave is a former pro surfer and revered innovative custom shaper. Brian is a mentor of surfers worldwide. Together, they have spent years designing boards at the testing grounds of Makaha Beach. When they designed the 1st known 10' SUB (stand up board), they took the sport to a new level. These are high-performance boards, the perfect blend of rocker and curves, allowing them to paddle fast and be loose in the surf; the most progressive boards today. Dave won the 2008 Noosa Surfing Festival for SUP surfing Event on this board, and with stiff competition. Finals had the likes of Bonga Perkins, Josh Constible, Brian Keaulana himself, Dave Kalama and Mick Dibetta.

Thinner and flatter than the C4 10-foot Classic, its soft 70/30 rails, balanced plan shape, even-tempered rocker and torque hungry vee panels make this new model one of the most nimble and versatile of the entire C4 quiver. The C4 Slingblade's classic longboard shape is turbocharged with the same potent flats and edges you see on the pro's board - letting you snap into a tight trim and stretch for five but also letting you slam it into high gear to whack the lip.

The 10-0 Sub Vector is a bit thinner and narrower that the original 9-3 SUB-Vector and the 9-6 SUB-Vector and is geared for larger riders looking for a good surfing SUP board.

Filling the gap between our 10'6" and 11'6" models, Da' Mooch is flatter, thinner and more foiled out than its sister C4 production boards. Da Mooch is a real Teflon-hulled long-scooter for the discriminating SUP boarder.

Designed by Dave Parmenter in cooperation with Charlie MacArthur (C-Mac), part surfboard, part whitewater kayak, part skateboard, the the C4 Waterman C-Mac ATB is the first stand-up surfboard exclusively designed for Training, Cruising; as well as creative and radical hotdogging in the new but growing sport of stand-up whitewater paddling.

The XP "Vortice" is a hollow, carbon-fiber version of the fastest SUP paddleboard we could come up with in 4 years of races in Hawaii, and is intended to be the foundation of a 'stock' class in the increasing number of races held in the Islands. This ultralight composite racer sports twin concaves running throughout the bottom, which increases both hull speed and stability; up top, the scooped out deck lowers the paddler's center of gravity while boosting the mechanical advantage of a shorter paddle shaft. The bottom rocker was honed in the gale-torn Molokai Channel, the gold standard of every paddlesport race on Earth. If you're into racing and want to 'railroad' open-ocean swells one after another like you scarf M & Ms, then book a test flight on the XP "Vortice."

In Hawaii, "holoholo" means to head off for a walk, a ride or a sail strictly for pleasure. The C4 Holoholo was intended for just this purpose. This coastal cruiser or flat water Stand-Up paddleboard was designed to enable the paddler to head off and gaze at whatever catches his or her fancy. Pristine kelp beds, warm meandering rivers, tranquil smooth lakes or whatever, just go ahead and effortlessly scoot along and "smell the roses." Although it is intended as a "cruiser," the Holoholo nonetheless is up to a romp in the surf for those intermediate or advanced SUP surfers who crave the ultra-glide thrills of the ancient Hawaiian olo boards. Includes a full-length deck pad, and multiple inserts for attaching cargo.
