The new raceboard sail looks good for light wind. Can you tell me what the maximum wind would be for an intermediate sailor and the maximum for an expert sailor.

Compared to other race sails, it seems to have too little battening and a small luff pocket to have much top end stability.

Can someone on the "Ask Our Team" please answer this question?

Hi Tony,
Which "raceboard sail" are you referring to?
I see nothing in the 2008 or 2009 Severne Sails range called the
"Raceboard sail"?
Do you mean the FOD (Formula One Design) rig?
Where did you see the sail you are asking about?
Can you provide a link?

Roger,

It's under the "boards" section, listed as "raceboard sail" and is included on the Phantom page.

Hi Rod r,
I took a look and other than the bottom of the sail in the photo of (Remi I think) the railed up Phantom Race, I did not see any details on the rest of the sail.
Did you find a photo of the sail all rigged and sailing?
Thanks,
R

Hi Roger,
Near the bottom of the Phantom page, there is a 14 line paragraph about the sail, and right at the bottom, the specs are listed below the specs for the boards...

Hi Rod,
OK, I finally found some photos of the raceboard sail.
Unfortunately I cannot answer Tony Matta's question as I've
never sailed one of these sails.
Perhaps Remi Vila can shed some light on this tipic.
Hope this helps,

Dear all,

I guess Tony is refering to the StarBoard raceboard 9.5 m2 sail as shown here :

...with specs described here:

http://www.star-board.com/2009/pages/products/v_phantomRace.php

I'll let Remi answer your query.

Cheers !

Thank you to those who answered so far. I hope Remi can answer soon.

I would also like to know if the 4 cam arrangement is much stiffer in rotation than the normal two cam sails?

I have just received my Starboard Raceboard sail. I have rigged it on my RSX 520 mast and I can't get it to rotate without pushing the lower batten around. I am afraid that I have already craked that batten after only a couple of uses.

It rotates nicely once it gets started so I don't feel that it is a mast diameter problem or friction on the cams. I think it is just the deep draft of the sail. The RSX mast has an IMCS of 32 which is as recomended on the sail. I had the maximum downhaul with the mast length set at the recomended 540cm and maximum outhall but still needed to push it around.

It is certainly light and comfortable to sail and keeps its stability as the wind increases. My only complaint so far is the rotation and would appreciate any comments or tuning suggestions.

Hi Tonymatta,

Sorry for the late reply but just arrived in Peru.

I use this sail to developpe the new Phantom Race 380 and use a Red Line 530 and the cams rotation is really nice. Perhaps your RSX mast is bigger or you have too much tention on the battens.

I use this sails easily until 20 knots, after you can be faster with an Overdrive 8,5.

All the best

Thanks for the Reply Remi

I have baught the redline 490 mast as recomended for light sailors. I tried it on the sail today, but I still cant get the rotation without pushing the lower batten with my hand or leg.

When I pump the sail, the top battens rotate but come back again because the bottom one won't go.

I tried loosening the batten tension but it only added wrinkles in the sail without assissting rotation. I also tried the boom in the top and bottom clew holes but no difference.

Does it matter what base extension is used? I am using a North Powerx extension set on 20. its maximum setting is 42. I wouldn't have thought that 12cm extra would alter the mast curve much.

Hi Tony,
Not sure if the longer extension is the problem, but I've seen quite a few sails, over the years, that had exactly this problem.
The combined bend of the mast and the extension is way too stiff, and if the top of the extension is anywhere near the front of the bottom cam, you get rotation issues.
Do you have an shorter extension (like a 26 cm) that you can try?
That might just take care of the poor rotation of the bottom batten.
Also, it's never really a good idea to put too much extension up inside your mast as it does affect (marginally in some cases, alot in others) the overall mast bend curve.
I'm looking at an older NP XT26 (Matrix 2000) extension at the moment, and if I set the ring at 20 cm, I measure 19 cm to the top of the extension.
From the top setting on this extension (26 cm) there is still 13 cm (non adjustable) to the top of the extension.
If you have a 42 cm extension, and it has the same 13 cm of non-adjustable area above the top setting, you would have 13 cm +22 cm (42 cm - 20 cm= 22 cm) or 35 cm
up inside your mast.
Does the bottom batten on the Severne Raceboard sail come anywhere close to 35 cm from the base?
If so, I think you would be alot better off (rotation of the lowest cam) and also you would avoid "point loading" the mast at the top of the extension by using a shorter 26 cm extension.
Mast won't bend at all in the area where it ovelaps the extension, so the mast will want to bend alot more right as it comes past the end of the extension, thus causing significant "point loading" in that area. Add the cam on top of it, pushing in the opposite direction, and you have a good recipe for a broken mast.
Hope this helps,

Hi Roger, Thanks for the comments. Can always count on you.

I don't have a shorter extension at the moment.

This sail has only five battens so the first one is fairly high. It is about 90cm up the sail. With my extension, I have a 12 cm minimum mast penetration so I have 34cm of extension inside the mast. The first camber is about 36cm from the top of the extension.

I found the comments below on a previous thread about mast rotation. I have sent Jesper Orth a private message as well to confirm his view on it. Do you think the same remedy would apply in this case? Also will it cause any harm to use the sail without the camber inducer in place?

....... Take the camber out of the sail. Cut with a hacksaw 3-4 mm of the camber end that is pressing against the camber tongue/ and panel inside the luff sleeve. ....

Hi everyone and happy new year.
I`ve haven`t used or rigged mentioned sail/mast combo but had exacly same problem with a Gaastra GTX. (And a Tushingham T.Bird)
Did find (especially with Gaastra) that by setting extension about 2 cm longer than usual and NOT downhauling any harder bottom batten rotated far easier. Think its to do with the angles downhaul rope makes with respect to mast.
Using exactly correct length and fully down haulling (Sp?) pulls cringle in towards mast. If ext. is a bit longer cringle can be a little away from mast but still be correctly down hauled.
I know overall length of rig is longer but find with both rigs mentioned its worth it. (I also leave bottom batten very slack ; prompting folk on beach " your bottom batten is too slack !!!) (Which it is but entire sail rotates easier)
Good Luck

Hi Floyd
Thanks for your suggestion. I did already try setting the mast length longer. I had the experience previously of setting the mast on my RSX sail shorter than the spec and the lower batten would not rotate. Lengthening fixed it but unfortunately not in this case. I also tried more and less downhaul without success.

To Remi

I got a respons from Jesper Orth saying that it was a starboard not Severne product and that I should address the concern to you.

I don't believe it is a good idea to cut the camber as suggested in the quote above because the camber doesn't have much plastic in the sides(I guess for weight). I have tried triming a little off the sail shoulder where the camber sits and have had some improvement in Rotation.

I can now get it around with a hard pump or two. Will it improve more with cutting more or is this of limited benefit only?

I can get it back to original with spacers if necessary but I don't want to cause irreparable damage to the sail. Help Please!!

Dear Remi

I am still waiting for an answer to my last question please.

should I trim more from the sail shoulder where the cam sits to help the cam to rotate better?

Hi Tonymatta,

Sorry but I was busy with 2010 boards.

I think your main problem come from the batten, a stifer one must be better, but anyway next I am working on the next VO2Max sail and will take car of your point.

All the best
