I've had good success with channel bottoms... I happen to like them on small wave boards, in combination with smaller fins and more rocker than your typical flat-rockered grovelers. Here's a section on channel bottoms that I wrote a couple of years ago in a chapter on bottom contours:
Like concaves, channel bottoms are designed, in theory, to direct water flow from nose to tail and in doing so, generate more drive and speed. They may also facilitate some ventilation or introduce some boundary layer turbulence, depending on their shape and length. But unlike concaves, channels do not alter rocker in any significant manner. Rather, channels are simply wedge shaped grooves shaped into the existing bottom of the board, whether it be flat, concave or (rarely) convex. The channels are most often toed in at the same angle as the rail fins, and may be uniform in width, or flared slightly from entry to exit. Typically 4 to 8 grooves are shaped into the bottom of the board through the tail section only, although some channel bottoms can begin to fade in at about the middle of the board. The long and deeper the channels, the more their effects are felt. The channels may fade out behind the trailing fin, or may run right off the tail rails and out the tail block. The trailing fin most often sits on the peak created by the two centermost channels, and the rail fins may sit within a channel, or on the edge of a channel.
Most commonly used on boards for small to medium surf, channel bottoms are effective in creating more hold and drive, but at speed have a tendency to become tracky. To compensate for this trackiness would require accelerated rocker, smaller fins, or a narrower tail, all of which would effectively undo what small wave boards are designed to do – plane higher, flatter and faster in weak or small surf. Still, channels do provide excellent hold on steep sections, conserve speed through turns, and add heaps of drive, and so modest accommodations can be made: smaller fins and (because bottom channels, like rail channels, tend to stiffen a board) a touch more rocker are common combinations with this design.

looks like walden's patented "magic bottom", to me. chine rails paired w/ double concaves. seems to keep the board nice & lively while allowing for a bit of extra width for stability. the "magic bottom", w/ the chine rails, allows the board to "turn like a narrower board" b/c the edge of the rail is tucked so far under the board, usu. 1-2". b/c of this, the OG "magic model" is very popular w/ the weekend warrior & beginner-intermediate set. makes them feel like they're better than they are.

Hah! That sounds about right. Thanks. From 12-21 i was a surf addict. But at 22 I joined the military.After an 8 year commitment to the Marines and no surfing I got back into it in 2009. I got a thin narrow short board and I sucked. In 2011 I got that thing and it definitely helped me find my mojo again. Now I ride a copy of the hypto krypto and love it. Your knowledge helps me understand why I can throw loose turns so easily on that thing.

glad to help. these types of discussions are what drew me in & kept me posting here in the first place. the reality show-like drama & pissing contests, not so much. i've posted more in the last 24-48hrs than in the previous week.
also, thanks for serving!
