Upwind Wing Sup

Message par IcSurf » mer. août 14, 2019 5:40 pm

Hi, for translation I will keep it short and simple.

I am enjoying my 5m wing on a non foil sup. I took a few waves with it today and its really fun.

I am hoping to learn to ride a sup foil to use with the wing eventually.

My question.. Today 12 to 16 knots wind I struggled to stay upwind and on my previous sessions also. Has anyone managed this on a sup (no foil).? If so any help with technique.. I am using a 10'6 30" JP Allround longboard.

Thanks
Ian

It is easy if you have windsurfing experience.

Otherwise, don't stuggle. Just get some centerboards or make them yourself with some plywood & strap:

That looks good. I have never wind surfed and have only a little wind knowledge. I will try a few more times and if I'm still struggling upwind I will purchase the centreboard you suggested. Thanks Colas.

Colas, i looked on a few forums and it seems with Sups with no foil it seems a common problem and like me lack of wind experience. One person posted this..


There really isn't much need for a centerboard once you get used to the wing, any board with a long straight rail is easy to get upwind. You move back a little on the board, get the wing a bit behind your center and it steams upwind. It's actually easy to push it into a tack.

I understand moving back on the board which I have been doing but I don't understand the get the wind behind your centre.. Do you know what he means?

You have to move your Wing not the wind just behind your Center 😁

IcSurf, that's part of the Windsurfing techniques, but they take quite a long time to learn, so I think it is better if you just screw a crude fin on a plywood plank and strap it under your board.

Otherwise, the wing is pushing you sideways, and the board + fin is resisting. By moving the centre of effort (CE) forward of the center of resistance (CR) you bear away from the wind, and aft you go into the wind:

adding a centerboard moves the CR forward so it makes the process easier. plus it stabilizes the CR, without it, the CR will move wildly with each of your movements and chop. Otherwise, you need both to dig the upwind rails in the water to move the CR forward and move the wing backwards. But It is easier to control the digging of the rail with a Windsurfing sail, as the mast helps you control the board. I think it will be much harder with a wing, just try to dig a rail with a SUP, it is hard to do consistently. Plus on a windsurf we have a lot more control of the sail and can modify the pressure gradient on it to steer with experience.

I could not find a pic of digging the upwind rail in low wind, here it is in high wind:
