Re: Inverse Rail Board

I'm thinking a couple extra layers of 4 oz. glass on deck side towards the rails in back (compression of glass in turns) might be beneficial both for longevity and also for more snappy flex of the "wings"

Yeah, probably just change your password should do it. AND if you use that password anywhere else...change it there as well

Re: Mermaid Tails

With entire working surface of fin(s) as single unit though, there is no chance of ankle rotation or loss of area from deformation. One big, slightly cupped surface maybe more thrust than 1/2 and 1/2 with split???

Re: Mermaid Tails

If you are going to build something from scratch you might consider creating a two piece design that could separate and be used when needed, and lock together when you wanted to swim like a mermaid (who doesn't want to do that lol). Excellent idea! Just reach down and pop a lever of some sort for e...

Re: Mermaid Tails

Step out of system would need to be designed so it remained locked on in a blender thrashing wipe out. Big fin area=lot of leverage the water will have to rip it off your feet

Re: 4'10

I feel like the concave deck makes a ridge outside of it on the rail, riding finless i'm usually over right on the rail, with my hip and elbow, would be interesting to see this ridden. I guess it would be more like greenough on a spoon. What's the board thickness in the middle? In films and stills ...

Looks to me as if it is on the racks w/ deck down so round deck and complex concave within a concave bottom

Now that's proper use of CNC tech, reproduction of a magic board!... ...and, what would be "improper" use of CNC tech? ;) Buzzing out hundreds of identical mediocre shapes using poor quality foam, then having low wage non-surfers scrub smooth and do crappy glass jobs on them.

Re: Thought experiment

It confirms that I have no cooking clue about understanding riding an incompressible fluid wave Probably will require quantum computer modeling to even come close. The best (for now and likely for always) is your approach, intuitive experimentation based on direct experience. Pioneers may get arrow...

Re: Advice for a total beginner?

One more tip, a lot of (all???) plywood has stiff flex in one direction (down its length) and is much softer and more bendy in the other (across the width. Orient your template so the length of your board is the stiffer flex.

Definitely an interesting concept and a cool look. Eagerly awaiting ride report!!! Always good to remember that those crackpot experiments sometimes yield pure gold.

Re: Thought experiment

I don't know doodely about hydrodynamics but won't the concavity down the center, between the scrolls, since it narrows as it goes back, create a lot of drag? All concaves I have ever ridden open up towards the tail... I'd love an explanation of any theory or if you have already ridden something at ...

Re: simmons type stand up for belly riding?

Never have done. But ponder the volume which is for arm paddling only followed by standing and skimming across relatively flat waves. I'd give one a go if nothing else was available but seems like it would be heck of a lot of board to wrestle.

Re: Swim fins and the winter.

The only little inconvenience that remains is that the filpper being bigger than my natural size, it is also harder to paddle (more surface), but this is something I ll get used to I guess. Yes, just a bit more muscle development from using them and end result will be greater thrust/speed. I go luc...
