View Full Version : Problem with Severne Reflex cambers

5th November 2010, 12:49 AM
I've been using the Severne Reflex sails this season, and have had major problems with the lower camber.

Rotation has been very poor, but the real problem has been the durability of the camber, it simply cannot keep up, and breaks. It's only the lower camber causing the problems, the others seem fine.

Does anyone else have the same experience with the cambers on the Reflex sails ?

Am getting pretty tired of this and need a more stable solution...

Hi Hank,
What size is the Severne Reflex you are having problems with?
What mast are you using in this sail.
How long is your base extension...... how much of it goes up
inside the mast?
Many times, if you have a long (48 cm +) base extension, the base extension
can make the bottom of your mast too stiff and cause lower cam rotation and
breakage issues.
Hope this helps,

Hi Roger.

The following sizes so far has had problems: 6.2 - 7.0 - 7.8 and 8.6
These are the sails I use most, so I might experience identical problems with the remaining sails well at some point.

Masts used are the recommended Enigma mast, the 8.6 is a Redline 490 though.

As for extension lengths, the Severne 36 extender and the shorter 16 is used.

All in all this setup should be more than compatible as it's the recommended.

Hi Hank

They reinforce this cam to be more stronger, pleas contact your Diatributor and make the warranty to get the new ones, thanks

All the best

Hi Remi.

Thanks for the info.

How do you distinguish between the original and the reinforced amber ?

When were the reinforcements made ? How, what do they look like ?

Last question, what do you suggest be done to the poor rotation of the lower camber ?

Hi Hank

The new cam are much thicker near the pin, it' s more than 4 mm thick

To help the rotation make sure that your cam is in the right position when you rig your sail, it should make an angle of 90 degre with the mast. The common problem is that when downhaul the sail you need to help the cam to not make an 45 degre angle

Hope this help

All the best

Hi again.

I need to bring up this topic again as I still haven't found a solkution to the damaged cambers.

Please have a look at the attached picture, the cambers are all identical, the lef tone however is damaged.
To me it looks as if theses cambers are all the newest version, ie. as Remi explains the 4 mm.

Anyone having input on this ?

What are the changes if any when compared to the 2011 version ?

No one having any input on this ?

Can anyone help identifying whether the above cambers are the old type or the new type ?

Remi, where do you measure the thickness ?

I can't find a solution to breaking the cams, they are of course aligned properly, they simply break after being in use.

Hi Hank,

I've been following the Severne Reflex sails for a while now and I'm even thinking of buying one.
In the ReflexII sails they seem to have solved the camber problem you're talking about.
That doesn't help you, of course.

Why don't you post your problem at the Serverne Sails site:

Perhaps they can help you over there.

Good suggestion, it's however not possible to attach pictures.

Furthermore I'm not really keen on using the Product feedback form on the Severne website, why bother when they state "Due to a large volume of messages we cannot respond to every comment received" - meaning I can't be assured that a reply to my problem will be made, top customer care...

It used to be ok to ask questions about Severne products in this forum, there is plenty of good info here, and the questions are normally replied to.

I don't want to start a different topic, I'm only interested in figuring out which version my cambers are and how to solve the annoying problem of breaking the cambers every few runs.

Hi, guys. Allow me to give you my experience with that problem:
with the code reds, and now the reflexes, I always rig the sails without the boom, and for me severne sails are extremely easy to rig. My sequenc is:
- give tension downhaul until the mast is at half of the sleeve
- put cams by sequence: 3 - 2- 1 - 4 - 5
- give the rest of the tension downhaul
with the 2010 reflex, when you put the cam nē1, you have to be sure, previously, that it is completely attached to the batten, because everytime it is only partialy attached. If you do not pay attention to that, the cam will twist while you increase downhaul tension and you probably do not notice it. After rigged, when you turn the cams to the other side, that cam nē1 normally breaks. Yet with 2010 reflex, you have to bring cam nē1 down with your hand while you are giving tension downhaul, so the cam won't leave its 90ē position to the mast

2011 Reflex II: This last problem - bring the cam nē1 down with your hand is not necessary anymore, because severne has changed the cam for a smaller one.
anyway, it's still important that you attache correctly the camē1 to the batten, before fixe it to the mast.

Last details that I've learned with Steve Allen at Flexeiras, Brazil:
- my first 3 battens are, on the reflex system, with minimum tension. He told me that the sails has very good power, so it doesn't need big tension at the lowest part.
- Severne Reflex doesn't work very well if you give maximum tension downhaul. It doesn't turn correctly, and you loose, while sailing, that good power feeling. You'll have very bad performance.
So, with my previous 2010 Reflexes and now with the 2011 ones - from 5.1 to 9.2 - I put with streamline base mast one 2cm above the sail says and give downhaul tension until 2 to 3cm before the limit tension (when the wheels touch). The result is, with 2010 and 2011 sails, my cams always turn.
Hope this help! :)

Hi all, I purchased a 2010 formula of 11mts reflex, and the rotation of the cams is very bad, I've been watching contais points and all I think it's ok.

Anyway it is possible that the tension on the luff is excessive? ppexeiro not understand your comment, do you think is best to mount the downhoul less than what you put into the sail

in 11 is 566, but I think a lot, it would be better for the rotation to 564? with 566 the sail is so flat and don't rotate.

Thank you!
