I have an older Waddell slalom 5.3. I looked everywhere on the sail and there is no luff spec. Anyone know what size mast I should use please?

It has grommets in the tack for the downhaul.

Thanks

Hi Darbonne,
Waddell...Trevor Bayliss... that's almost pre internet!
I would try the sail on a 430 mast first.
Remember, the top will not "twist off" on a sail that old.
The did not design them to be floppy on the top.
Best you can do is to get a 430 mast and downhaul unitl
the battens pull back to about the back of the mast, and
the luff sleeve become fully tensioned around the front.
Are you sure there are no specs on the sail bag?
Hope this helps,
Roger

Thanks for the reply. There are no specs anywhere. I measured the luff the best I could and got 178" which is about 452cm so I was thinking 460. But I don't know. If the mast is too short wouldnt that be worse than too long. I'm a complete noob and want the smaller sail to learn on. The other sails that came with the stuff I got are 12.0 with a carbon 580cm mast and boom. Should I bother getting a mast for the smaller sail or just try to learn on the 12.0? Once I learn maybe I'll get some post internet vintage sails.

Hi Darbonne,
No, you will not learn a whole lot, very quickly, on a 12.0 m2 rig with a 580 cm mast.
Too big, too heavy, too hard to rig.
A 460 mast would be a bit too long for a sail with a 452 luff length, and a 460 mast will be too
stiiff as well.
Shorter masts have a lower IMCS bend ratio number, which means they bend more easily with less
downhaul tension.
A 430 mast with a base extension on 22 cm (452 cm) would seem about right, but I would bet the final setup would be more in the 456-458 cm range.
Does the sail have an adjustable top fitting?
If so, and you have a 460 mast, then you can adjust the top strap to make the sail work on a 460 cm
imcs 24-26 MAST.
Hope this helps,
Roger
Might want to head to a shop and see if they will lend you a used demo mast (a 430 and a 460) and rig the sail on both masts and have them give you an opinion on which works better in the sail. Just rig it in their parking lot or on some nearby grass. They may even help you and give you their opinion, hoping they can sell you the mast.

The sail does have an adjustable top. I am working with Tommy at Gulfport Boardsports He is going to hook me up. He said 430 as well. Can't wait to go sailing.
