The load must also be taken into consideration as well as its counterpart buoyancy. And speed, too. Then, of course, there is the impact of form drag produced, not just by the legs but by other body parts, arms, hips, etc, that may be hanging over the outline. I thought all that was obvious? And, wh...

So much for trying to keep a complicated subject simple. So, its not the amount of planing surface per se, but more the characteristics of the planing surface, particularly the relationship of the length of the hull to the width of the hull. Naval architect, Lindsay Lord referred to this as the “asp...

I don't believe that rocker has anything directly to do with lift. If anything, rocker slows a board down when going in a straight line. Your shapes tend to be smaller (less planing area) than mine. You may have come upon a combination of volume and planing area for your weight that, while fast, doe...

Not an easy question to answer....about 1" at the centerline. But, then there is a great deal of "V" in the tail, so there is a lot more rocker out at the rail. A board with no rocker is fast, but resists turning. The rider has to weigh the tail to bring the rail out of the water in o...

Here's the latest G5...it boasts a whopping 40L volume to accommodate a 300# rider. I had to exceed the prescribed length by 2 in in order to achieve the desired volume. Dimensions are 52" length, 23.5" width and 2.5" thick at centerline (thickness at rail is close to 3") Using A...

Belly Rider is very familiar with multi-foiled fins. Maybe he will give you some feedback.

I like the bottom concave...very Lindsay Lorde/Bob Simmons. Nice transition from down rail in back to up rail in nose. Not easy to do with such a short distance. I'm interested to hear how the grooves in the tail affect control, assuming that's their purpose.

I can't swap out hull form boards in the middle of a wave! If the hull is the appropriate length and volume for the riders height and body weight, there is no need. One simply lowers the leg(s) if added drag is desired, or raises them for maximum planing efficiency, all the while maintaining a posi...

"on a given shape (let's pretend it is a basic bodyboard shape), would adding skegs allow the board to go faster by any way ?" There's no short answer to that question. There are just so many variables to consider. Wave conditions, bottom contours, board volume, not to mention the obvious ...

I agree that extended legs can and do extend the "wetted surface". But that "extended surface" creates a lot more drag than the form drag of the hull. Its that extra drag of the legs and swim fins that can be used to control direction, much like dragging an oar in a canoe. Taken ...

Prone boards turn off the rear corner. My guess is that turning a prone board is more about rail shape,outline shape and presence or absence of fins than length.

Asier, Have you read all of the threads I've posted on this forum? You'll find the answer there...

“I find it is the opposite of surfboards. So, the bigger and heavier the wave the smaller the board you can ride. Since those waves give so much more speed you just increase your control by using a smaller board which is super helpful when making crucial late drops or bottom turns on slabby waves. F...

Looking forward to seeing the finished shape!

More bottom curve, yes...more outline curve, no.

All things being equal, e.g. rocker, volume, rail shape, bottom contours, fin set up, etc, straighter rail line = more rail in wave face = more drag = less speed Drawing shows a comparison of a G5 with a Mach 7-7. The G5 is 49" in length and the Mach 7-7 is 42". The yaw angle for each rela...

Good questions...The outline of TB needs to be considered relative to all of its other design features, which includes the use of fins. The outline shape of the finned TBs speaks to the difference between finned and finless prone-board shapes. The TB designs are driven by the use of fins for primary...

When I stand up surf, my feet are pretty much on the stringer, with maybe my lead foot a little more towards the wave and my trailing foot a little more towards the beach side. If I stood on the rail, the board would roll over. Its enough to just put my weight on my toes or back on my heels. That's ...

Ha! Could definitely use your feedback. I have a couple of lefts in mind that only need a solid summer Southy to light up.

I spent the past week refining designs for surfcraft at the extremes of the length continuum: a 12’ “glider” style surfboard and a 52” prone board. The prone board, dubbed the “G6”, is the latest iteration in the T-Belly line. As I’ve discussed elsewhere on this forum, the previous TBs were designed...
