FWIW, you can get aluminum sail track. I've got miles (or so it
seems) of black anodized AL Harken track on my boat. IMO, _the_
"right" way to attach anything to an AL mast is to drill and tap the
mast for ss fasteners and then isolate _all_ of the parts with Durlac
(or similar). BTW, I'd be very grateful if anyone could point me to
a source for Durlac here in the States. It seems silly to ship a tube
up for New Zealand.

It isn't the same stuff but I have used 3M 5200 to insulate
aluminum-stainless joints with success on masts and spars.
