I have a chance to buy a this sail for $50
it says it needs 2 new cambers, but other wise in great shape,
stored indoors.

so my 1st Q, can i rig it on my 460 mast with a 30-40 cm extension?
it it possible?

my 2st Q, can i use it without buying new cambers?

i will be using it on my old longboard on light wind days,
the other sail i have is a 7.2, so i figured this sail (8.1 for $50) would give me more fun on light wind days compared to the 7.2

any thoughts...?

thanks in advance

460 with 40cm of extension would probably be close enough.

sail without any cambers would probably not be a serious issues, considering what it is to being with.

This sails age, regardless of condition , well unless I had no other option,

would stay in the driveway. Walk away.You be much better off spending twice as much for a newer sail.

If you only think about freeriding in displacement mode in very light wind, a larger sail might not help the fun factor. I use a battenless dacron 6.0 for that. It is super light and easy to manipulate.

If the wind is stronger, maybe just below planing, a large and light sail can be fun because you can really rely on your harness, maybe rail the board, etc... In that case, a newer sail will be better (altough heavier) since it will be well stabilized for the gusts.

That sure is a bright sail! Maybe you could use it in a Toyota Tundra ad!

Simple addition 460 + 40 equals 500 so that is 15 cm short of the luff length needed, won't work. Maybe you can find a tip extension. That sail is about 25 years old. I owned a 6.2 in that model and it was the worst sail I ever owned. No range. The battens were super soft, cambers didn't do anything except to stop the battens. Just sew the batten sheathes closed, don't spend a lot of time, money or energy getting it to work, or don't buy it. dhmark

North Speed TCC, a very good mid '80's sail, you can use a standard 30 cm aluminum mast tip extension on your 460 mast.
Or, you can buy a length of wooden dowell at a hardware store, the same diameter as the tip of your current mast, and use aluminum duct tape to securely tape it to the tip of your mast, the 30cm you need. Wrap the aluminum duct tape maybe 7 complete wraps around both the dowell and 4" of you mast to secure it solidly.
TCC's were very good sails, super durable, and had a hint of modern twist at the top 2 battens.
Yes, you can use it without cams.

If I recollect correctly, North sails of that vintage required flextop masts. If you've got a constant curve mast, even if it was the right length, it wouldn't work very well. However, use of a tip extension might help out a bit with tip flex, but most tip extensions of the time that sail was made are too big a diameter to fit modern masts. If I were you, I would pass on this sail, even if it was free.

you may be correct in your addition. But something is wrong , the luff indicated is 5.15 , maybe its 515 or maybe its really hi tech 500.15


I think the Club at Windance gives away better suited that this is

Yep, that sail might be OK if it was free, but at least in my neck of the
woods, you can find a better sail for $50, even in the 8M range.

Almost EVERY sail made in the mid to late '80's, that "required" flex top masts, actually worked better with constant curve masts.
Certainly Windwings and Waddels, and I suspect the TCC, would work better with CC masts.
However, I'd offer 20 bucks for that old sail.
