I have this odd size 500cm Powerex mast. It's 80% carbon. IMCS 32. Ideally, Id like a light wight 9+ m sq sail for light wind.

I have a 9.5 Pryde V8 1999/2000 In very good condition that would fit on that mast. You can have it for free. It's located in Dunkirk NY. I won't be there till late June. I will ship it at your cost. I also have Pyrde Spirit 8.8 that would work.

So it's a soft top mast I take it. Hotsails Maui & NP bein examples of soft top. NP being softer. Good to know.

All my nails are HotSails with Speed freak 8.5 as biggest.

I would be surprised if it is a soft top mast. Powerex has been CC as long as I can remember. Per their web site.

http://www.powerexmasts.com/bend_curve.php

You can always measure the mast bend yourself. I measured my Powerex mast & got 63-74 for a difference of 11% which is within their 1% tolerance of their 12%.

Powerex is a constant curved product, esp this old.

Any sail that uses cc will work.
Sailworks Ezzy Aerotech, Northwave, North, Simmer, Goya.

Older versions of Naish, Gaastra, Maui Sails, Hot Sails, NP have a hard or soft top preference, the PX , will work just not as well

I just wanted to elaborate a bit on the older Neil Pryde and Gaastra sails mast bends. I might be off a bit on the dates.

Neil Pryde sails were constant curve through the 90's with Fiberspar constant curve masts being one of the preferred mast options. Barry Spanier left Neil Pryde in 1999 so all of the sails designed before that time were constant curve. Not sure when Neil Pryde made the mast curve change but Sea Dog's 1999 V8 is most likely constant curve. His Sprit sail which was probably made a few years later is most likely a flex top. Having said that I do have a 2003 Neil Pryde Diablo 7.4 which I use on a 460 Fiberspar 100% carbon mast. It rigs up without any issues and seems to work just fine.

After leaving Neil Pryde, Spanier joined Gaastra as part of the Team. Gaastra sails at that time were constant curve and they remained so during the time when Spanier was their sail designer. I have a set of 2002 Gaastra Manic wave sails that even has the preferred mast written on them. The preferred mast was the Fiberspar Reflex Wave which is definitely a constant curve mast.

Spanier then became part of Maui Sails in 2005 so sometime around that date Gaastra moved toward using the hard top masts.

Check the
Unifier mast chart for the specific year, to see when and if a brand changed.

I believe my NP Spirt 8.8 was circa 2002 The mast I used was a powerx 520 which I had cut about 10cm off of. 5cm from the top, 5cm from the bottom, I was satisfied with the 9.5 V8 and the 8.8 Sprit on the mast.

Interesting. I thought Spanier was the driving force behind hard top masts first at Gaastra and then at Maui Sails. Maui Sails masts were hard top .. although I have seen plenty of Maui Sails rigged on constant curve masts (including old Fiberspars) that looked better than on Maui Sails masts. One MS race sail that I bought a MS mast for never looked right. I later learned from a former MS team sailor that this particular year rigged much better on softer top masts.
