Re: TP Displacement Hull Board

All surfcraft have "form" drag, some more than others. Drag is not always "bad" and is required to achieve control. Question becomes "At what point, and under what (wave) conditions does that form drag become more of an impediment than an enhancement to performance?" One of the advantages of using A...

Re: Finless observations

Hard to find fault with speeding along in trim on a wave like that, regardless of what you got going on the bottom.

Re: TP Displacement Hull Board

"Plowing" is almost always a nose rocker problem. Entry rocker has to be smooth, continuous (parabolic) curve, with no abrupt changes. Smooth transitions can be can be hard to achieve in a shape with such short length. "Belly" or convex rail-to-rail curve doesn't cause plowing.

Re: TP Displacement Hull Board

Aesthetically, I think the T-Belly Hull is one of the most elegant looking shapes I've done. Functionally, Daryl's ride reports have be frothing for a similar shape. Great winter board for California right points. Ride is similar to the ride characteristics of the tri-hull "Manta" I did a couple of ...

Re: The Misfit

The TBG5 is what I call a modern planing hull, which is designed to ride above the water rather than through it, i.e. displacement hull. This shape is essentially the TBG5 stretched out to 5'6" and widened to 23". Rocker has been increased at both ends. This is necessary whenever you lengthen a shap...

Re: The Misfit

Thanks Keith...I try to focus on what works best. Form follows function
Prone riders are not as hung up on the “current fashion”. Maybe kneelo guys are the same.

The Misfit

This one is a 'tweener, falling somewhere between a proneboard and a kneeboard. Dimensions are 5'6" x 23" x 2" 38L. The fin array is set for a knee rider, which is how I intend to use it. Kneelo guys like to have the fins located where their ankles fall (or vice versa) At least that what I've been t...

Re: TBXL

The one thing I found from bodyboarding over the years is the the bigger the wave the smaller the board I prefer. I haven't had the time to devote to the XL design and testing, but I think Keith is on to something here. Going smaller as wave size increases reduces planing area, which in turn reduce...

Re: Bodyboards discuss (the soft paipo)

Leg/fin dragging is a good example of drag applied in the service of control....The Waikiki beach boys use to drag their feet to initiate a turn on their skeg-less paddle boards, modern SUPers and surf kayakers drag their paddles for a similar reason.

Re: Finless T-Belly

The "waggle" is what I call it, and I experienced it the most when I would duck dive. Very pronounced and unsettling, almost enough to pull the board from my grip. Very odd; no explanation for it. Never felt it when riding, though. Sorry Keith, I've already sold the FX to BellyRider, but intend to a...

Re: Finless T-Belly

The lack of scientific rigor plagues all surfcraft design theory. And, yes, we are all left with mostly subjective data on which we hang our design theories. Subjectively, I can say that surfing finned is to me more enjoyable than surfing finless, regardless of the size of the surfcraft in question....

Re: Finless T-Belly

I've had the opportunity to ride the FX a couple of times now, and I have received feedback from a customer who owns a G2, G3 and FX, as well as plywood paipos. Our consensus opinion is that the FX performs as well as any finless prone board. And as a a finless shape, it takes different lines than a...

Re: TBG5

Here is the G5 bottom and outline adapted to a 5-11 kneeboard. Owner liked it so much, that he ordered a second one with 1/4" less thickness. As a shaper, I really enjoy the applicability of this design. I could imagine a 5ft'er for you guys who enjoy the "mega" prone board approach.

Re: Bodyboards discuss (the soft paipo)

Great find, Keith...really interesting stuff. One of my early Boogies (maybe a "Comp" model?) was blue with the red and white layered rail. I didn't realize that was functional, only thought it was decorative. It was a major improvement over the first models which were super flexy. I added the twin ...
