Being relatively lightweight (about 65kg) I have finally got myself a few of the Severne Redback sails (they are on sale ;) ).
On land they rig a little different to what I am used to, so I'm just wondering if anyone here are using them regularly?

There seems to be a lot of built-in shape right next to (behind) the mast. The battens do not rotate past the mast but rather bunch-up/bend right behind it, it looks quite odd compared to other sails that I have owned.

Below is a picture of the 3.8 when it was rigged on the 330 mast from severne, it looked even worse on a 340 mast.
Once on the water I did pull a little more outhaul, compared to the first picture, and the sail worked really great on my old EVO 62 board. Best sub 4.0 I have ever owned. :)
Just wondering how other people are rigging their Redback sails?





After sailing and a bit of more outhaul:

You've got a few vertical creases coming out of the bottom batten so I would say it needs more batten tension.

Looks like it needs a bit more outhaul in the top photo.
They have quite a knuckled shape, meaning that its fullness is far forward.
I know a few people on the Gold Coast that use them and they love them.
Maybe a tad more downhaul too, like 1cm more might help.

My son had a full quiver until he got too tall for the boom cutout and switched to S1 so I've had a few years experience with rigging them.
Agree with windsmurfs comments. more downhaul top photo etc. found the measurements on the sails to be accurate. If you are using the 330 xs3 mast be carefully as it's not meant for adults.

Also found Redbacks rig a touch shallower with the adult masts.

Fantastic sails really. Highly underrated. Getting used on the pwa. The new version just came out. Thought it worth mentioning you gotta be shorter to use them as the boom cutout and clew are lower. Tall light people will struggle

Thanks for the advice, I'll do some more tuning the next time. I'm 175cm tall and the boom height in the pictures worked fine for me, it was about 140cm from the end of the extension (if I remember correctly). The power comes from much lower compared to my blades sails, so the boom doesn't need to be as high up.
I haven't used the larger sizes yet, but will use the "adult" mast in those (blue line).

I have had two lightwind session on the 4.7 redback now, very nice sail indeed. Lots of power and very easy to regulate the power with the backhand. Works great as a float and ride sail. :)

Below is the 4.7 on the recommended settings (rigged on a blue-line mast). I have fined tuned a little around that but it seems to be spot on for a great low-end. I guess the slightly odd shape near the mast is part of the design, so one shouldn't try to tune that away. So I'll try to just trust the design and tune for a nice feeling on the water :)

Severnesails must have learnt from Ezzy sails. Ezzysails have always used that saildesign (No RAF sail). That method gives a "foillike" built in the sail. I don?t know if other brands use that design.

I wouldn't know, we never get to see any of the Ezzy sails around here, and we have only had a national importer for a few years, around 2018-2020 (afaik), and they don't seem to be very active anymore.

When downhauling the sail, and before attaching the boom, the batten-tips are heavily bent to a point which doesn't feel quite safe for the battens. I have not seen that on any of the other sails that I have or have owned. But I also do not have any of the Gator or NCX sails, these may have similar built in shapes.
