Here is one not that silly setup for light winds. A big but not too slow front wing (SAB W1100, 2100 cm2 in this clip), and a light weight freestyle rig. A rig that is not too big + a big foil combo allows all kind of fancy pumping, like that "rowing through the air" type of pumping at 00:45, and that one in the very beginning at 00:05. Neither of these are easy (or even possible?) with big and bulky sails I think.

180 cm and 34''. I am not jumping though, just an occasional forward every now and then.

What kind of and how small swell you have, that you need to pump? Just make lots of turns and this keeps the speed up and keeps the foil happy and flying. Zero pumping here for example:

For me the 969 370 is great for relaxed cruising around, but I am light weight, 72 kg. For you it would work for swell riding for sure.

In a way the old Sabfoil mast/fusealge connection was similar. They relied on 2 M6 screws, but the idea was more or less the same - the mast was pulled into the fuselage, not reaching the bottom, and the angle of the side walls ensured tight fit when tightened properly.

The issue with their connection was that somehow just the initial tightening of the screws was never enough for the mast to settle deep enough. After a bit of riding and jumping the mast managed to sink a bit deeper, and at that point the screws needed to be re-tightened. If continuing riding without re-rightening, the screws managed to become even more loose after a while, due to vibrations I guess.

F-one's M8 screws and a bit chunkier connection will likely help with both of these issues.

You are making it utterly complicated. Just take your favourite wing board and enjoy the ride ;-) 60 L board here, and next not zero PW experience, just 3-4 times trying it. My point is... it's not that complicated.

If moving the front wing further forward would not help to "fix it" then the board was not that good to begin with. It's the board designer's task to come up with an idea where the rider is supposed to stand on the board, and to distribute the volume and to shape the board accordingly. The foil should then be positioned based on that.

There is not much point to try do it the other way around - i.e.: to place the foil first (wherever you can), and then try to figure out where to stand, to make it work.

Different foils suit different placement. GoFoil V2 v Armie mast position would be 300mm at least. How does a designer solve that??

Easy. The designer solves that by using tracks that are long enough. For example this Sabfoil setup was even more extreme than Armstrong in that sense - that is, due to the fuselage design, the front wing was even closer to the mast. Yet, since the tracks were long enough and well positioned there was no problem to move the mast further forward, and to get a perfectly dialed setup.


My point was that on any given board there is a sweet spot where you should stand. Only then the board would be in balance, and only then the board would interact with the water as the designer intended. If the tracks are too short then either find out if there is a different fuselage for your foil brand (that positions the front wing further away from the mast), or make the tracks longer, or use another foil with that board.
