Found a reasonable used North mast which seems to be 460 cm and 15 % carbon.
It looks to be in good shape.
I am still looking for a 460.
As a heavyweight in a lite wind region, my sails are 7.0 and larger and go on 490 and 520 masts.
Luckily my 7-oh still fits on a 490, but one day, I hope to use more modern sails.
As such, I imagine 30 % would still be the starting point ??
my current masts are 75 % and 100 % - as marked.
as you go down in sail size i have heard one can get away with less carbon.
and obviously many are using RDM in the smaller sizes now as well.
as usual i am just trying to save some money, but the more i write here, i guess a North 460 15 % SRS is out of the question ??
thx in advance
How much is it? $100 or around that? just get it.
I got a 2nd hand 100% carbon powerex for $150. Seems to go pretty well on my large sails.
I think bend curve would affect the sail shape more than the carbon content.
I wouldn't stress too much about it. I only just started paying any attention to different sail and mast brands.
You can tune most rigs to be pretty dam good. Play with it and fine tune it rather than worrying about the carbon content
Hmmm 15% carbon would be a pretty old mast.
Likely to be very very wrong for modern sails regardless of how you tune it.
Just to be sure though, what markings are on it?
Hi Joe!
I wouldn't get the mast, Mark has a point there will not work with the new sails.
Good Sailing
Dani.
I'm not sure I agree with that, I have a really old low % carbon mast that works really well with my 2010 Koncept.
You're looking at this mast with regard to using it for a sail you don't have yet? I'd get the sail first and then buy a mast so you can rig them together and see if the mast bend suits the sail.
mark and wespyyl have good points
somewhere in my windsurf life i promised myself to ALWAYS use the "appropriate" mast.
this does NOT mean it HAS to have the sail manufacturer's stamp on it, but it MUST at least fit the curve.
For this I have found the unifiber mast selector "tool" very useful.
However, never be fooled - there is apparently an "older" NP mast that works on the hard top Maui Sails %^&*()
so, older may still work with the new sails, but it is a bigger shot in the dark
UNLESS one knows a bit of the history ...
thx for being patient with me
