Hi! I saw this thread and edited a small clip from some exisiting footage to show how I uphaul on the small wizards. A visual summary of the many of the tips outlined by everyone else. :)
Hope it's useful for some!
I came across this on another foiling forum. I rarely see the uphaul sequence of a foiling session on posted videos. Uphauling isn't generally very glamorous so I understand the lack of presentation in video. It is obviously really tricky in choppy bay waters as I have rediscovered while learning to foil on a Wizard 125 / Infinity 76. I haven't had an uphaul on a windsurfing sail since 1985 so it's been an adventure to uphaul a sail again. Flat water uphauling is no problem on the 125 but add chaotic chop and I would rather waterstart. Though if I can master a reliable uphaul method in chaotic chop then I can use smaller sails and not be overpowered when on foil. This video shows a quick "clean and jerk" style. Emily's uphaul video is super helpful as well. Visuals are helpful for learning, thanks to all for the technique and tips videos that have been posted!
Uphauling the 86 litre 152cm Horue Femto
I would like the chance to up haul a small sail. On my local river, with the current going against the wind, we have sizable chop that quickly develops. I don't find it easy at 205 pounds dry, to up haul a sunk 7.0 sail on a 140 board. Its my least favorite thing about foiling.
Uphauling any board--any board--requires volume and center of float.
First, based on your weight you need enough board volume to float you. Should be obvious.
Second, move your feet fore and aft until you have your center of weight (including the sail) over the center of float. Wherever that ends up being, that's where you stand. No preconceived prescriptions are necessary, such as straddling the mast base. Just move your feet fore and aft until you find it. That's your spot.
