Hi all
Iv'e recently acquired my first cammed sail after exclusively using non cammed free ride sails and I was wondering do you have to pop the cams off the mast before pulling the mast out when de rigging or can you just slide the mast out, the user manual does not state whether you have to or not?

Serverne say take off boom and then let downhaul off and the cams just pop off, they do but I prefer to let a bit of down haul off then pop the cams off then remove boom and pull mast out. I think it puts less stress on the battens and cams.

Agree. With max out haul.

What cammed sail?
Some you loosen downhaul and cams pop off. If you do different, battens can break behind the cams.
Some you loosen down, cams stay on, and you pull mast out.

What Ben said.

Only with what remery said

In my opinion it is a good idea to let some downhaul off with the outhaul still tight then pop the cams off the mast by hand. Depending on the cam type then can rotate a crap load befor they pop off which risks breaking battens. Just reverse the rigging proceedure.

Sorry forgot to mention its a north ram 8.5m F11 (3 cams). old but used only couple of times still like new condition and i got the platinum 100% mast with it. Looks like a very well constructed and quality sail. If it sails half as good as it looks I'll be happy.

I've e owned a few of those , great solid sails . Powerful.
Derigging . As above , Loosen downhaul six inches , pop off camms by hand then release outhaul .
Make sure , and it's an effort , to downhaul to the indicator dot on the top panel or it will feel heavy and a handful.
Ps , you can take out the bottom cam , it's an option , makes it slightly less cammy , but it's still a beast.

What brand? That a good question,
With Severne, I always did as above. Never have any problem.
But with NP I just finished replacing 3 battens broken by cam.
So please advise what will be the best - SAFEST - way to derig NP evo sails/

The NP V8s are just as bad at breaking the tips of battens . For EVOs and V8s definitely as above . If you don't they explode off the mast .
Ive broken the tips off battens on both those sails , while sailing . It seems to happen when I under downhaul when the winds a bit light .

With Severne you have to re-downhaul a bit after popping the before taking off the boom, or it get a bit messy.

+1

I have maui venoms ...but i always let downhaul off then pop them of by hand because i didn't like the sound of them popipng off
with just letting downhaul off ,as it always seemed as though the cam would rip the luff pocket ...I think this gentle approach will prolong the life of your sail..it only takes a minute or so ,but good observation mob dog ...Rams are great sails .

Tardy has the solution.take the gentle option.l use prydes,have done for years.Never bothered with the slow approach method of derigging my sails.new sails can be expensive,so l might start now!

I have 2020 Duotone Warps I remove the boom, let off about half the downhall, manually pop of the cams, release the balance of the downhall, then remove the mast. Reasonably quick, painless and protects the tips of the battens.

never had to, if you let to much downhaul off the boom head can get hard to reach inside the luff but you only need to let let it off maybe 6inches to get the cams off.

on the other hand its way easier to do with my overdrives, I find the Turbo GT a real pain to rig and derig, mast is really hard to get in and out without 2 people and cams take way more effort to get on. Takes me longer to get the mast in the turbo then it takes me to rig and derive the overdrives

Have had Evo 4,5,6 and now the 9's. Got rigging and tuning tips from the Dutch NP importer for each modelyear. All rig and derig the same way.

Rigging, open the zippers, put in mast over the cams. Downhaul until 15 cm to go. Snap on cams starting at the one above the boom, top one next followed by the one below the boom and the bottom one as last. Fully downhaul, check if cams are square to the mast. If not? Push them in the right position. Mount boom and apply outhaul. Again check cams, sested correct? Close all zippers.

Derigging is exactly the other way round. Open zippers, release outhaul, remove boom, release downhaul tension by 15 cm. Push the cams of the mast from the bottom cam upwards. If the cam doesn't release either release a bit more downhaul or gently push the sleeve down near the monofilm panels.

Have done so since I switched to NP in 2012 and have never snapped a batten or broke a hypercam.

This is what i do too. Removes the more complicated boom removal process without breaking batten tips.

The videos for the TR-3 to TR-9 Maui Sails cammed sails showed removing the boom, then loosening the downhaul to let the cams pop themselves off the mast. The problem with this method was that it made short work of the battens. They bent too much and did not last very long.

The solution was to de-rig in EXACTLY the reverse order of rigging. This means keeping the boom on out full outhaul, loosening the downhaul a bit, popping off the cams by hand, removing the boom, then all the rest. Doing this saved my battens. Much more time and more steps to de-rig, but you save your battens.

Bought a used Maui Sails Titan from a friend. Two broken batten tips when I pulled it out of the bag.. He'd followed the rigging videos.Blaming the videos, not him.

That, de-reg in EXACTLY the reverse order, is what I always did with my cam sails (NP, HSM, Loft) and never really had a problem ...

The new EVO 12s are very easy to de rig, the cams push off the mast with ease even with 60% downhaul.
I rig and de rig the same way the Tank described.^^

I've had KAs and Duotones and I do the same. The Duotone XT 2.0 mast extension makes it easy.

Rigged and de rigged the ram a couple of times in the backyard for the first time since I got it. sure does raise a sweat compared to my ezzy cheetahs much more tension in the downhaul required, not to bad when I oil up all the pulleys, just doable without a downhaul crank, anyway all cams on and off with ease when done as recommended above all the rigging gauges min and max lined up with stated measurements, looks very powerful with that deeeep draught, scary even !, the only problem I have is I cannot remove the wrinkles radiating from the bottom 3 battens. there was some small ones in higher battens and they disappeared with a tiny tweak of the batten tensioner, but the bottom ones I can not work out. Ive tried backing them off and re tightening/ working from top to bottom and vice versa and nothing seems to work. There is no broken battens and all tensioners are working correctly, I can hear them creaking and see them curving the battens. Although the sail is old it has only been used less than 10 times and been in storage for years so im wondering do I need to take it out for a good flogging a couple of times to maybe stretch it out and then try tuning again? Also I found a print on it that says switch cam, does that mean that I can remove the cams and use it without them, not that I will this is my first ever cammed sail that's why I got it. Also one more question, I got the platinum 100% mast with it, this is also my first ever full carbon mast and it is very light compared to my other masts, only 2kg 490 SDM. Can this break easier than a 40 or 60% mast? I do have an ezzy hookipa 90% 490 RDM but it feels heavy and solid compared to this north mast.

I couldn't tell much difference with the bottom cam , so I left it out . Makes rotation a bit easier . Those crinkles don't look too bad . Under load is when the sail has best shape .Dont overtighten too much especially the top ones . Slight crinkles is OK . Too much and it's harder for the sail to flip to the other side .
It looks good
Dont forget that bottom strap , it makes a big difference to power .loose makes it less powerful . When you tighten the strap you will see a lot more belly in the bottom of the sail . Gives it more low down grunt .
Welcome to the world of camms .
PS , Don't worry about the Big Bang noise when it flips to the other side .( which you will have to force with a big tug on the boom in light wind ).

Oh good that puts my mind at ease. I thought maybe its just how the sail is, their not like normal tight crinkles all bunched together more like just a few gentle waves spread further apart. your not wrong about the big bang tried it a few times while rigged, scared the s#*t out of me, craaack like a sonic boom I thought I broke something.
