New H fin board

[SURFFOILS]

They are magnificent boards to look at , I can only imagine how fast they are to ride.

As for the angled front section.. my story is that I tried every different version of traditional foil design that I could find, all sorts of materials, conventional scientific theories for several years. then I tried the complete opposite and it worked better than anything else. Im just saying if you get a chance, try every angle, even the opposite, it might not work but you learn so much.
Maybe try it without the angled section or maybe the two long side foils like I have and see what I experience.

New H fin board
After going through a short small board faze and having some of the beast waves of my life on the black board .And after some deep reflection on witch of my ‘’ can you make a better body board ‘’ experiment s is best , here is another stab in the dark . this will be the last red board , I have used up all my red foam .Because funds are running dry quality was compromised buy using off cut bits off foam, the join lines show when the board heats up a bit. And unexplained bulges are suggesting water in the foam. I have learnt my lesson. But I will use the board as is , I am looking forward to the first teast ride

Cool board details and dimensions are awesome, what kind of "maneuvers" can this particular board can do? I really want to know..... Looks very cool.

Hi Jarrett
Thanks for the complement ,I don’t do so-called manoeuvres I think my style is old school I ride a wave to make it so no elrolos, spinners etc,i have an odd paddle out technique instead of duck dive under white water I pop over the top ,the fin tips sometimes pop my large bulk out the water, it can go horribly wrong if you miss time it .Common technique with long boards ,do other prone rider use this method ?.My favoured so-called manoeuvre is a floater rentry, seems to skip on top of the white water, but its best in the vertical zone it gets amazing horizontal drive; it’s got traction, or grip. The only back to back comparisons I get is riding body boards, they fell to me like driving a car with the tyres flat , mushy .

2016 Christmas collection told you they would make good decorations

Did you see the shock wave propagator in front of the foil?

Chrispi,

"shock wave propagator" - that''s way out of my realm . Is the SWP the big thing in front of the foil? What does it do?

Certainly the board opened up options for surfing - you don't need a clean wave face.

On one of the pics in that clip, I am shore I could see a conical nose, on the front foil like a bulbous bow ?

All these foils are from the same design foil from the Air Chair and that twin foil design comes from the Big Front Wing and Small Tail Wing concept from airplanes. Th bigger foil/ wing gives the majority of lift and the rear foil/ wing adjusts the AOA of the front foil. So the efficiency of the rear foil is compromised as it's a controller. The further apart they are the more stable and they provide lift via the Bernoullian concept of high Vs low pressure over opposite sides of the foil. They require constant and uniform speed to be effective and stable.
A foil with a rounded leading edge has a greater effective angle of attack but is slower and a sharp edge foil is the opposite.
