Anyone have any idea whether a Severne Gorilla 430 RDM Constant Curve will work "more or less" on a 2022 NP Speedster 6,4 (luff 450) Constant Curve Flex Top ? I see the NP and Severne masts 430 both have same ICMS 21 so its just the top part that differs slightly. I get that its not ideal, but is it a deal breaking bad idea ? - not looking for race course performance, just got the chance for a cheap deal and fancy giving it a go but not interested if have to get a more compatible mast. Thanks for any thoughts.
I think Severne is more of a hard top because when I rig them on Ezzy masts, the leech looks too loose up high with barely any downhaul. Sailable but not as good as with a Severne mast.
With a flex top sail it seems like severne masts would make a really tight upper leech and not have good release at all?
IT will kinda work ,but I would keep looking for a Pryde mast ,the speedsters is such a nice sail and it would be nice to
use the correct mast , Tushsingham would be closer ,but Pyde stands alone in the flex top zone ,
People have issues with masts that are supposedly compatible , just due to diameter at cam locations. Or slight curve changes that are just enough to cause sticky rotation. Given we are also now adding in the NP vs Severne and then also that the gorilla is a wave mast I would not even consider it.
Edit - oopsie it's a no cam
I think that the older versions of the "Mast selector" are much easier to read, se below (V1 2019, if I remember correctly).
Severne and Neil Pryde have been on the opposing sides of the scale for a long time, and although Severne is slowly approaching the centre of that scale it will never be a good fit in a Neil Pryde sail.
Thanks yes the curve looks clearly different. Local shop confirms, dont do it.
However I think that bend at the top looks kinda speedy and the blue sail gives me a break from so much Severne red (me and most other locals) so will persevere and seek a mast.
thanks all
There's only one way to find out, just try it. Normally stick with the preferred mast but if you have the sail and the mast, just rig it and you'll get an idea of the shape. If that looks ok, give it a shot on the water.
If you haven't purchased the sail yet, just stick with Severne. It's used that much for a very good reason I'd avoid mixing brands in your quiver anyway as you end up carrying more gear around and I like the similar feeling of different sails from the same brand.
And in case you forgot, Severne rigs the other way around so if you also use their boom and extension, it's get pretty annoying rigging a NP sail.

You should be good using the Severne 430 with the NP Speedster. They share the same ICMS, so while it might not be perfect, it'll work for casual sailing.
Speedsters till 7 ,2 size work perfect with gunsails 70% masts RDM.
I use speedsters with my future fly foilboard and starboard racefoil .
Most nocam sails from NP work perfect with the gunsails masts. Just dont used in v8 , rs racings or rs flightsails.
