On another forum (ahem) I've come across a statement that a camless sail will pull you up onto the plane quicker than a cammed sail. The poster referred to some test results that supported this (unfortunately unavailable). I'm sceptical about this.

So then, all things being about equal (boards, fins sailor etc), and say you have a pair of 7.5 freeride sails, one with 2 cams and one designed without, which would get you going first?

I say cammed, as the foil is more rigid so the tiniest amount of apparent wind will start to produce power... whereas in a non cammed sail there will be more tendancy for the leading edge to collapse with the pressue of apparent wind.... unless the windward side is filled with wind well.

Gut feeling only.....

I think its more about the softness of the sail.
A very rigid Race sail is harder to pump with then say a no-cam or 2 cam free ride sail.
of coarse once going the Cam sails really pushes through the lulls a lot better.
never actually tested it head to head though.

i reckon this.... non-cammed are just a bit easier to pump, never had much success pumping cammed sails, but then I haven't used them much

however a cammed sail will be better for staying planing in the luls. I reckon if you can work on pumping technique with a cammed sail, it would be better for freeride/freerace style sailing

Reading between the lions lines of your Q Ian da new Lions really do have a huge wind range
I always reckoned my camless Retro's got me planing earlier but since I bought a new 7.5, 2cam Lion (only used it 3 times so far) it's got about the same bottom end doesn't need as huge a pumping effort to get planing and a much better top end.
About halfa kg lighter than the Retro, and 1kg lighter than my old Race sail, no mono, rotates almost like a camless sail, prolly never be as fast as a race sail but lots more fun IMHO

id say definitely cammed but are we talking per square meter here or what because wouldnt you usually take out a much bigger cammed sail .

Boards magazine tested this about a year or so back. They compared 2 point 7 sails. The ac3 and the camless version, size was around a 7.0. The results came back that the no cam rig planed earlier and was faster on all points of sail, except deep off the wind, or when the wind increased (overpowered conditions).

I think alot depends on the cut of the sails for example I went from a loft o2 freeride 6.6 to a KA Koyote 6.6, both camless freeride sails, the loft had definately more bottom end but the KA had better mid to upper range stability. Next I went from the koyote to a Koncept 6.6 with cams. The bottom end is about the same for these two but the overall stability and high wind stability are dramatically increased with the cams. So from my experience a camless sail built for grunt will plane faster than the same size cammed sail built for speed.

I looked for thiws online but couldnt find it, but still

Given this, I am wondering if anyone has tried the NP Hellcat back to back with NP H2? I am at a crux where I am about to buy my first ever set up of go fast gear and want to get it right so I can up my GPS speeds to the max they can be through Winter. Any experience and feedback welcome. happy to go rotational as they will work on my XCombat masts, but if they are indeed slower will go the whole hog. cheers

I have a 6.7 hellcat and it is a beast, real early planing, non stop acceleration.

I keep up with guys on rs racings

The h2 is ultra light, good for light wind, but if you go cam, go all the way !!

I have 7.8 rs slalom which really fast and good at going through dulls/lulls (?forgot the name?).
But just don't fall with the blessed thing.....[}:)]

The hellcat is still my all time favourite, I'm looking at replacing my old 5.7 saber with the new hellcat

Recently I purchased Hot Sail Maui Speed Demons, a 7.3 and 6.6. From My GPS I'm finding them quite fast. Getting consistent 28 knot speeds on them and a nautical mile of over 26 knots. I find them quite light in the hands, soft handling. It's easy to close the gap on them and rake the sail back. They are stable in the gusts. Every time I sail with them, which has been only a few times I think I'm learning a bit more about them. I hope to get over 30 knots with a Speed Demon fairly soon. I'll aim to improve my nautical mile too.

I'm really enjoying sailing with them. The price was very good too. They are beautifully finished with for example leather covering high wear areas. As funding permits I plan to buy an 8m and a 6m Speed Demon. In my eyes they look a bit plain though. A lot of clear mono film. But the way they work, makes up for the looks. Great value for money.

I've used cammed sails before, Pryde and North race sails, an RS 6 7.2m and Warp 7.8m. For someone at my level they don't offer much improvement in performance however they are a hassle to rig, are heavy and are not much fun to waterstart.

All things being equal -Twin cams should plane earlier and push through lulls without coming off the plane as soon as a No cam sail.

In the Severne range the twin cam sail- The Turbo - will plane earlier and hold through lulls better than the no Cam NCX.

But the NCX actually has a faster top end! Falling somewhere between the Turbo and the Overdrive.



In fact the NCX is widely regarded as being the fastest and best handling no cam freeride sail you can get you hands on - testers conclusions. I think we need to do a better job of making the public aware how good the NCXs actually are

you could say we need to get windsurfers to

" NCXPECT more from your freeride sails "

There are 4 or 5 NCX reviews from the magazines on this page: so you can take someone else's opinion into consideration.

http://www.severnesails.com/2012/media/test_result.php

i think this will help anyone researching their fast no cam freeride purchase. The conclusions are quite convincing.

All This performance comes at a price - usually around $50 to $100 cheaper than any serious competitors in this category.

In all respect, that may well be so but I traded my (unused) 6.5 & 7.5 NCX for Ezzy Freerides. Not happy with the look of them in terms of durability.
I know a guy who bought an NCX and the stitching was coming undone. He traded it for an Ezzy Infinity.
I have now bought Ezzy Infinities and they may not plane earlier than the Ezzy Freerides, (hard for me to tell as they are a different size), but I prefer them as they are more stable as you point out.

I just want a waveslalom sail with the removable cams that I can use on my Bombora

Then I have the best of both worlds.

Uncle Neil made them in 1989 and they were rad.

I had the RAF-CAM waves back then, from memory just a single removable cam above the boom. Nice sail - pastel colours - AWESOME.

Thanks for your responses guys.

I got an email from Pieter at NP, and he said that in normal conditions the Hellcat is very fast, and just as fast as H2 and RS Slalom. But when it gets to the overpowered stage that is when the RS Slalom comes into play as it is more stable due to the cams and wide luff sleeve. Pieter said the Hellcat can still be as fast when overpowered but requires a really good technique in these conditions as the Hellcat won't be as stable and easily held down as an RS. Great service being able to chat to the sail designers online.

I had some very early KA's with removable cams, very weird!

Personally I found that the early model NP Hellcats didn't have a lot of power when tuned to spec, no where near the NP Saber. You either had to tune for power or top end. However I recently rigged an 2012 Hellcat at a windless demo day. I noticed that they had a lot more shape below the boom than previous models, so I'd say that they've beefed them up.

Personally I'd go for camless in smaller sizes for more manouverability in hi wind / rough water and cams for larger sails for great range, stability and speed. Many of the new Cammed sails are now softer and running RDM's which makes them very nice to pump.

^^^^^^^ Good advice - Chris and Sam from WSnS recommended cammed big sail and RAF smalls.

Thanks also to Mark Jordan for his advice and letting me have a run on his 113L Falcon - that thing moves!

Ended up 7.8m RS Slalom, 6.7m + 5.7m hellcats - ewwwwwwwwwwww! Just in time for this weekend!!!!!

I'm certainly no expert by any means but aren't cammed sails generally for overpowered situations where you are trying to go as fast as possible? they have more battens and will be more stable when overpowered as the battens will keep the sail from distorting and the COE from shifting. Cams for top end.
Where as the non cammed sail can suddenly fill up with wind and pop you up onto a plane with a quick burst.

Will finally be able to keep up with ya now Phil The Skate is quick, but not as quick as the F2 Stoke I sold ya. Remedying this with a 2012 113 Falcon as I missed the extra speed so much

lets keep talking up a glassy surfing weekend. hows the surf at towns today - niiiiiiice

Cams can advance both top and bottom end

Depends on the sail design and all the other variables.

The Turbo is designed for low end grunt - and sailing moderatley powered up- with an easy rotation (its a different cam)

While the Reflex 3 has all the technology to deliver incredible bottom and top end

Took me a while - January 2011 issue. Clones mini test. (I only have this on iPad, so I can't scan it sorry)

I'm always curious about sail maker claims that they have better great bottom end and top end. Compared to what??

The question posed was which is will get you going faster, cam or no-cam? If you read the mini test boards did, the same size sails, from the same manufacturer, that are targeted at the same market (free race / slalom) the no cam is generally faster, earlier planing and so on. This was an objective test, same gear, same conditions, same testers, only changing between sails. I reckon that answers the question, and everything else is just opinion and spin.

I have more feeling of the wind in a no cam sail, i feel i can get up and go earlier, and it is usually a lighter sails. However, hard to compare, those sails are not design to do the same Job. Usually guys rig bigger cam sails because it handles the upper wind better and then will get on a plan earlier than a smaller no cam. ;-)
