There's a 5.7 Sev blade for sale in the forums and I'm wondering how it'd go on a 93ltr JP FSW out on botany bay. I've got a 460 constant flex mast and I wont waste my time sailing in less than 20kts. Spose i need a shorter pole. I want a sail that's going to hold between 18-25kts. I haven't uphauled in 15 years and the JP I've got feels too light to try (at 85kgs). Had my first sail in 15 years a week ago and ****ing glad i can still get up without an uphaul. . I love the look of this sail and like the write ups. What do you guys recon?

Sweet. I think I've found my one-size-fits-all sail. Just gotta find a cheap secondhand mast. Thanks!

I'm 78 kgs. Assuming your mast is the right curve for the sail, they rig nice and absorb the gust quite well- for a wave sail. If you have a constant curve mast and want a more spongy / forgiving sail, the North Dukes are great. In a freeride sail, the Loft 02 / Oxygens are tops also. There's two 5.9's on Seabreeze atm.

Hope this helps.

This might be a dumb question but if you already have a constant curve mast at 460 long can you hacksaw 30cm of the bottom and make it a 430 and would it work the same? those powered masts are a good masts and it seems a shame not to use it.

It's crossed my mind mate, but can't find anything in the formus in favour of doing so

I have a Loft O2 and love it. Its a 6.6, but really handles the gusts well. I have it out in up to about 20. I weigh 75kgs.

Don't rig the Severne sail on a constant curve mast. I had my Gators rigged on constant curve masts for about 5 years. I recently swapped all of my constant curve masts for a set of used Gaastra stiff top masts. I could not believe the difference in feel and stability that I got from the using the correct masts

If you use a constant curve mast you will probably find that the leech twists off early, leaving you with a lot of curve and belly in the lower part of the sail. It might feel rather grunty with so much curve in the lower part. On the flip side it may well feel perfectly fine.

PS - Cutting 300mm off your 460 mast is a really stupid idea. The mast will be too stiff for the sail and will most likely make it feel rubbish

You need a 4.30 witha and extention longer than 21 as stated!

I was asking the question regarding the mast as I have recently broken the bottom of a mast and I shortened it by 10cm to cut away the cracked area plus a little more, rigged it sailed it and it seems fine, can't tell any difference, I have noticed in this forum previously one of the highest ranked gps sailors frequently cutting bottoms of masts to have minimal extension and wanted to know where the line can be drawn regarding how much can reasonably be cut off without unduly effecting performance.

Mast required is 430 long with a stiffness of 21
sails luff is 442 cm long therefore 430cm mast plus 12cm of extension = 442cm.

Cutting off 100 mm wont make any difference except for the need for 100mm extra extension. But if you do it to a mast that is longer than the recommended mast just to make it fit you end up with a mast that is too stiff. If a high ranking gps sailor is doing that it may be because he is unusually heavy and loads the mast more than normal so the bend he gets with a stiffer mast approximates the bend an 80kg sailor gets with the designated mast. Otherwise his sail performance is probably suffering. As I understand it the heavy weights of this world (like AA) use the recommended mast.

An ideally trimmed sail does much of the work for you. You sheet in and weight your harness and just go. The ideal sail just flexes away at the top in the gusts and you don't have to vary your sheeting or your weight distribution. You just hang on and go. If the mast is too stiff you can't do that. The gusts pull you up on your toes and you have to actively control the sheeting. You know that overpowered feeling? As a lightweight I'm familiar with it :)
