Yes they look nice. I had a look at the Mach 1 and Overdrive M1 last week. Shape and dimensions (at least for the 7.0) seem similar to the R7 & R8 Reflexes....there are changes to the bottom panels and battens (and obviously no Reflex tensioners) and they are reportedly lighter.
Colours look very smart in real life.

In the words of Stu the pirate "my wallet just caught fire"

I reckon that might be a proto Hyperglide...?
Great photos BTW

It looks like the sail on the picture above is a 7.5 . May be that Severne will have new sail size' s for 2018.

Wow, it seems to make those formula boards lift right up out of the water.

...and here comes the overdrive m1. credits to windsurfing44

There are a couple of pics of the sail rigged over at windsurf ultimate speedchallenge's Ned127 page on facebook. You can also see Pieter Bijl (former NP, currently angulo boards) commenting and elaborating on the sail's characteristics which makes one wonder whether he has been employed by severne as well.

Pieter offers a sailtuning service for any brand of sail. From what I've heared Twan Verseput contacted Pieter to tune his sails for the Luderitz Speedchallenge. Besides that Pieter was still distributing Gun Sails and giving rigging/tuning tips for Gun up to last summer overhere in The Netherlands.

I see. Pieter has always been helpful and prompt to reply back in his NP days.

I attach 2 pics from the (provisional?) catalog albeit with not too many details.

Just spotted a mach 1 with yellow logo at the luderitz speed challenge page on facebook for those interested. I wonder wether this colour scheme will be an option...

My Mach1 sails arrived this week and got out for the first time yesterday - on the foil with the 7.8m. The sail looks great with the new blue highlights and rigs very easy (on a Apex mast) . I downhauled to the specs straight off, which I found a bit different to the old Reflexes- it usually took me a few outings to get near these with the old sails. I think the two top inducers need another small spacer to get the luff pocket looking spot on , but everything else was good straight out of the bag. The boom length is shorter than last year's model by a few cm but the sail looks quite similar to the R8 (minus the reflex adjusters). The sail shape is nicely progressive from the bottom power zone to the top leech and cam rotation is effortless.
On the water the sail felt very responsive to wind gusts and overall quite similar to the older R8. Probably the main difference seemed to be that the sail is a little more tuned to a higher wind range than the old R8 7.8m. Handling in the transitions felt a bit lighter.
Obviously more TOW is required to confirm my initial feelings. I'm very happy with the new sail and keen to try out the smaller sails in the range.

Tried my 8.6 the other day and confirm it felt great right out of the bag. What I really like is how they are always improving the little details. No messing around with setup, rigs great to spec. It does take a little more down haul tension but still rotates sweetly. Great Xmas present.

Looking forward to getting a lot more time on these in the next few weeks :)

I've ordered a 7.0 and I never bought a new slalom sail and I do not have a lotnof experience in tuning slalom sail. How's the batten tension? Do you need to adjust them...top cam requires a spacer? You deduct that by having wringle around the area? Thanks

It will be top of the line from severn, so minimal adjustment on battens, thanks for the reply!
