Severne mast
Hi Ian
Could you give info about the Red Line masts ?
Is it constant curve ( north ), flex top ( like NP ), Hard Top ( gaastra ) ?
BTW : 490 is the size I am considering to buy.
Thanks in advance !

Hi Daniel,

Jesper is the guy who really knows this 490 curve in the most detail, I'll ask him to give the full detail ASAP.

Cheers ~ Ian

Hi Daniel

What sail do you want to use the 490 Severne Red Line in?

The 490 mast is closest to constant curve. It would be best if you can reply what sail you are using, and we can advise you.

We have a strong mast program (performance/ strength) and aim to deliver Severne masts that can be used with other sail brands.

By the way I have not heard about any broken Severne Red Line masts, for a long while, used/ sailed under normally conditions!!

RE: Severne mast
thanks for answering.
Honestly, I am still thinking about the sail... but the options are V8, Daytona ( Rec mast is a 4.60 plus extender =) ) and GTX, in 8-8.5 range.
What do you think about using the RedLine for those sails ? Wich one would be the best combination ?
Thanks in advance !

Hi Daniel

If you can't get hold on a Severne Overdrive 8.5, that is in the same category as the sails you mentioned, and in many sailors opinion a better sail. Then V8 and GTX will be OK with the Severne Red line mast. It might even perform better? The only sail I'm not 100% sure the mast will fit is the Daytona.

RE: Severne mast
Hy Jesper,
I wonder if my NP X9 Ultras 460+490 will 100% perform in an Overdrive 8,5-7,5-6,5 ?
Any suggestions?
Best regards Pascal

RE: Severne mast
Hi Pacal

We have only good/ positive feedback, that your NP X9 460+490 will work in the Overdrive 8.5, 7.5 and 6.5.

Best regards

RE: Severne mast
Hi all, I've been using Severne race masts, ( S-racing 490, 520, & Redline 550) in NP V8's for a couple of seasons now and I can confirm that the performance is very good, better than the X6. The only drawback is cam rotation is not as good - kick & punch. I also know of a person who was using X6/X9 in Overdrive, and also had a great result.

Hi Jesper, was just wondering if you can be of help to answer my questions on the compatibility of Severne Redline 430 Skinny and my Naish Boxer SL 7.0m (2007). The boxer SL is a very special slalom cammed sail designed to use on 430RDM mast. I used to fit the sail with my Gasstra Skinny C75 430. Yet I sold the mast recently as I'm looking for upgrade to a lighter one.

Am doing some research recently and found that Severne's Redline's got the best weight amongst most skinnies in the market (1.5kg for 430; 1.35kg for 400). Yet I still got some questions:

1. How compatible it is to my Naish Boxer SL 7.0m (2007)
2. Any compromise in terms of durability for the feather-light feeling in hand?
3. Can I also ask which one is more durable? Red-line or Blue-line. Would the full carbon version be more brittle? Would one would you recommend for general use. Prevailing condition is 15-25knot. Flat water with little chop (0.5-1.5m).

Apart from this. I've also got 3 other Naish sails:
Boxer 5.4(2005), Boxer 5.8(2005), Force 4.7(2005)
They share the same Powerex 400 Taper mast.
The mast is wearing out. May I also have your info on the compatibilty of Redline 400 RDM on those sails?

Looking forward to have your reply. Thanks for help.
