Gotta get used to the swing weight, rail to rail, so it feels "normal" paddling out to the waves.
Those with carbon foils can disregard.
My Hover 122 is easier to paddle with one 8" wave fin than it is to paddle with a 70cm foil mast, alu fuze, and gen 1 1220 foil. All that underwater swing weight just accentuates my side to side instability.

How is an 8-inch fin as stable as 28-inch fin with a counterweight?? Sorry physics is against that argument.
In flat water the foil will make the board super stable and easy to paddle. In disturbed water the foil can make the board move around a bit.

Try it. Let us know how you go.

Ah, I see you are the voice of NO experience.
Notice the qualification.
A 14 lbs. complete foil with a 95 mast will pendulum you right off your board, when standing ski stance in rough water.

Really? Ok vid of you standing on the sup in rough water with the wave fin and then with the foil. You might be surprised by the result.

In fact, after sup foiling for a while try and stand on any sup without a foil.

Oh, my foil mast is 70 cm, with gen 1 1220 Naish foil.

LeeD said..dead weight at the end of a long lever.

It is called a counterweight and adds stability compared to an 8-inch fin.
Do a little experiment. Have your mast hanging vertically held from the base by one hand. With no foil attached move it from vertical to horizontal. Then attach the foil and do the same. Which is harder to move with or without the foil attached? Let me know your findings.
Then add the stability of a 29 inch fin compared to a 8 inch fin.

You're probably dealing with mast flex underneath the water on that old flexible naish aluminum mast.

Sure, but tell nme you actually TRIED it!
I've tried it 3 times, once flat water, twice high tide and backwash.....same spot, less than 3 k ot breeze.
Adding a pendulum does not help stability.

All theory, no actual experience.

Ok, so you have not paddled with a foil attached.

LeeD you are either a troll or a totally clueless advice giver.


I cannot stand up at all on my SUPfoil board without the foil attached.

Weight of alu vs carbon has little or nothing to do with it.

The stability the foil gives in flat water is due to the huge surface of the foil&mast resisting roll,and a bit in pitch.
The bigger the foil wing and the longer the mast the more stable it will feel.This stability will "feel" very different from that given with width on a normal SUP.

As Hilly pointed out, in moving water the foil will induce roll,pitch and yaw movements as it hits eddies and turbulence.But it will always be more stable than without it,just takes time to be able to anticipate and adjust to its reactions.

Support. YES, the foil MAST helps with stability.
NO. The actual foil, if it is heavy aluminum, can osscillate and pendulum at a different rate that you and the rails are trying to achieve, causing a delay in rail pressure and also a momentum effect.

Are you saying you paddle it with the foil attached to the mast?
Doesn't that 9 lbs. foil pendulum left and right as you press your right foot and left foot down to balance?.
Why not use just the foil mast?
Leave the foil in your car.

I was just responding to the OP's question, because exactly like him I'm a competent wing foiler (and kitefoiler), and I'm also wanting to gets some skills, fitness and general familiarity paddling a supfoil with a view to trying it out in the waves, so I was happy to just ride around the same setup.

I was curious about whether the mast on its own would provide the necessary stability, but I haven't tried. Maybe I will next time and report back.

+1, nothing to add.
