Was also going through my sails and was wondering if my newly acquired HSM SPF 8.5 could be used on snow n ice. Apparently the PVC window is fragile in the cold. That's a pisser :-( NEVER thought to check that when i purchased it... My MS-2 8.0 is way too busted up to even consider winter activity and the TR-4 8.4 is just too precious = "my precious" done in the voice of Gollum from Lord of the Rings :-)
In any case, I found a 2007 Sailworks / SW Retro 8.0 for about $200 at 2-rad. Bruno marked it as A+ and owner from Gatineau marked it as B+. With the small crinkles near the top of the luff, I will give it a B+ while the rest was A+ with lotsa life left in it.
and another angle on the sail:
Bruce Peterson now has a clip on youtube on the proper rigging of the SailWorks Retro:
Now, back to winter windsurfing ...
Here's an old clip with the Maui Sails MS-2 8-oh. It was light wind and not so fast. To make it more interesting, it was sped up and some "futuristic" sounds that are supposed to be music? added.
The sled in that video was the ice sled. On the ice such a large sail is ONLY used in very light winds !! Mostly such a large sail is used on the snow sled. The version I am using this year is as follows:
My snow sled is loosely based on the race sled used by Langis Carron who used to race cars and then started racing in the snow at WISSA events and did well !!
Since there was discussion about a hard top mast and sail slated to be constant curve/CC on iwindsurf ...

I decided to try my NP 490/90% mast on the SW retro discussed earlier in this post. The issue was that the hard top/HT mast seemed to create a looser leech rather than a tighter leech - even with less downhaul. This is based on the photo earlier in this post and multiple riggings... Here is a photo of the NP flextop/FT mast in the SW Retro 8-oh. Same 10 cm downhaul and 40 + 180 cm outhaul as the HT mast.
Ok the leech looks loose, but upon careful examination this happens above the SW "cog" indicator. Before putting the outhaul, the battens pushed hard against the end of their respective sleeves. With the outhaul at 40 + 180 cm the battens actually seemed better than with the HT mast. The 10 cm downhaul was also taken down to about 7/8 cm and not the full 10 - just like the MS mast. And so, decided to take it out on the ice n snow for a spin. Will post the video once uploaded to YouTube...
Here is one video sample with the SW Retro 8-oh on the snow using the NP mast:
