MK3

I still feel foils will give better lift to drag numbers than parallel to water flow rails .This is also an experiment with vinyl wrap, I don’t know how long it will stay on. Its 10mm Airex foam core with 20 mm top and bottom polyethylene foam plenty volume, the vinyl wrap is epoxy to the polyethyle...

Re: Immigrant board Mk2

I have been thinking about a box fitting to run stand-up board fins horizontally on the rails .lots of interesting profiles to test. Not certain they can handle full horizontal side load.

Re: Immigrant board Mk2

The lift to drag ratio of a winglet is better than a sliding rail, so the same lift with less drag. So at the same speed a wing will have less parasitic drag compared to a sliding rail were the low pressure wake is mostly unattached

Re: T-Belly G6

The rail and trailing edge are looking good, I found a wide square trailing edge generally very fast, but dropping down a vertical face they make the center of lift move to the outside tail making the rider move back to control the pitch, dragging more bits in the water.

Re: New summer Groveler

How about a heavy rider compared to a light rider on the same board on identical waves with the same experience. Who will be faster, or ride the most distance

Re: New summer Groveler

As a small percentage of the total riding weight the board weight cannot have a significant effect on performance . How can you measure it?

Re: The Immigrint board

Thanks for the fantastic response, only problem it’s getting harder to decide .Back zip must be the way for me, my arms don’t rotate well. I presume a 5/4 for north east of the UK .

Re: New summer Groveler

I think a lot of people don’t see the overall picture. The overall weight has to include the rider. The board weight as a percentage of the total riding package can’t be that significant, except when doing unloaded airs, where getting it back under the rider is important. I think science says more w...

Re: The Immigrint board

Thanks for the advice. I was surprised at how few beginners try prone boards. In Newque, during the week I was there, I saw maybe 5 body boards compared to hundreds of stand ups. It’s surly easier to get into good waves sooner riding prone? Wetsuits, what’s the vote on rear zip or front pull over. I...

The board has been tested in small weak waves at few Newquay beaches fistral north, tolcarne wedge, and crantock .Can ‘t believe how bad the crowds were, and how many surf shops there are, ten times more than my home city Durban which is considered a surf paradise, warm water good waves mild all yea...

Re: T-Belly G6

That explains exactly what I am trying to do with my board, getting a thin foil rail in that high lift area, but retaining inboard volume.
