Duotone F-type as go to sail for light wind lake?

Oscardog,
Yeah, you have a quiver that's .... okay.... but may be making your foiling more challenging than necessary. First, it needs to be said: you don't have to change anything. However, you probably will find things easier if you do. Up front - I"m on of those that believes cams work well for foiling somewhere around 6 ish and up and no cams below.

The challenges of your current bigger sails: The Vapor is big (and I'm guessing not having sailed it) a pretty open leach and pretty stiff. I don't know how well it pumps for you but you are losing the effectiveness of some of that sail area because of the leach. The longer boom length means that you are just a bit less stable in the gusts if there is any hint of backhand pressure. The Aloha, again I haven't ridden it, has less structure (fewer and most likely softer battens) and no cams so that its too flat in the low end and then when it gets gusty the center of pressure will wander, again, making things unstable. What you need, imho, is something in the middle: cams for low end power and smooth power delivery over a the wind range, reasonably short boom length, enough structure so that in the gusts you aren't dealing with both the sail and the wandering CoE which makes riding level a challenge.

iirc, I've read the F-type 6.8 had some problematic cam rotation that interestingly the smaller size didn't have. If you can afford new, there are a number of good foil options including Gaastra Airride, Severne Foilglide, Gun Raise, Sailworks Flyer and the Ezzy pair of extreme bottom batten and not so extreme bottom batten. To these, you can certainly add most freeride 2-3 cam (e.g Severne Turbo, Gaastra Cosmic, NP V8) sails which work fine for foiling as they rotate pretty easily, don't have the extreme open leach of their pure race brethren, are a bit more easy handling.

Here's a good review of some of the choices (and you can find more reviews on their site). Use Google Chrome or translate if the language is a barrier: marseille.glissattitude.com/blog/windfoil-test-ga-voile-airride.html

Hope this helps.

I use a Goya Fringe 6.3 and a Nexus 6.9 for foiling, both on the same 430 mast and carbon boom.
Both are amazing sails, the Fringe for Freeride or WWF and the Nexus for Freerace foiling, using according foils, Moses Tortuga 873 or Aeromod LW.

The Fringe feels more "pumpable" than the Nexus, which feels more stable, so both sails have about the same windrange (with the respective foils).

At your size and desire to be out in 8-15, I'd bias it towards the larger offerings. Also note that most dedicated freeride foil sails in the larger sizes are cammed - for a good reason (Foilglide, Air Ride, Flyer, F-type, Skyscape, Raise,, Phantom Iris X). fwiw, I started off on a good no-cam in the size area you are talking about and moving to a cammed sail was eye opening in smoothing out the power delivery and generating it at the low end, especially as you are gliding through lulls, you don't have to worry about the sail deflating and losing shape.

btw, please verify with your seller the F-type will rig on an sdm. There seems to be some confusion that while the published specs say it can, the sail bag and sail suggest otherwiser: www.windsurfing33.com/forum/viewtopic.php?f=42&t=117065&hilit=duotone+f+type&start=30 (look for the glissattitude comment)

Thanks, lmk how it sails

Took the Duotone F-Type 5.8 out on it's first voyage a few weeks ago. I HATE cambers but gave this a try and LIKED it a lot! Cambers were easy to set and rotated with ease. Lot's of good low power. You really do need an RDM for it though.

Thanks all for the advice, bought a Severne Foil Glide 7.0. Tried it today in 10-15mph, gusting to 25ish. It's night and day vs the 7.5m Maui Aloha and my big 9.6m Gaastra Vapor. The Foil Glide is so light, with cambered power down low, cambers work well on SDM (thanks to North Beach Windsurfing for testing) and are easy to rig.

Can pump it maybe 2mph more than my other sails.

This now my go-to sail.

Love it.

I84 Slingshot, position C, small blue rear wing, 91cm mast

Go pro extension on clew end broke following a breach and catapult. As go pro is at bottom of lake, have no evidence. Have a new Akaso camera and a camera floaty on the way.

I have a 8m Hyperglide and a 7.7m Venom race sail.

The Hyperglide is lighter by around 500g or so.

Does it plane any earlier than the 7.7 race sail using the same board and fin - barely.

I notice a huge improvement in bottom end when I switch from my 6.8m 3 cam Loft Switchblade to my 7.7 but only a small improvement when I change from my 7.7 to my 8m which is to be expected with only 0.3m of sail area difference.

A 0.9 metre of extra sail area will make a huge difference to bottom end.

I find it impossible to believe a Glidefoil 7m can match the low end power of my two larger sails never mind a 9.5m.

If I am wrong then I want one asap.

I'm 90 kg , David Ezzy Hydra pro 8.5 does it all for me . this sail is incredebly tune able . I use it from almost zero wihte caps to 18 knots . This sail is very easy to pump compared to a cam sail . I had a Flyer 7.0 , Naish Lift 4.7 and 5.7 also very easy to pump but a 6.0 Hydra pro is on its way and 8.5 , 6.0 should cover a whole lot of wind . A very important thing whatever the brand of your sail , is the mast , if the mast is not compatible with your sail you will never know how good your sail is especially to pump in the lightest wind range for this sail .

Here is a video of Foil Glide 7.0 in my normal wind conditions, probably 5knots gusting up to 12+ knots. You can watch the water for idea of wind speed.

Ooops wondered how Severne were using Glidefoil which is a Pryde name. Foil Glide it is. Good to hear cams are easy to put on. If a 7.0 can get close to a 9.5 I will go there. My XO 9.5 irritated with tough cams and weighed a ton when wind dropped off and you had to balance waiting for wind. Depends on fitness though I am sure but if you dropped it an 'easy uphaul ' was required or four letter words.
