Lots of choices actually but few people would like the look on a mast. Those red & blue fittings used on braided aircraft hose are anodized, for example - would look kind of gaudy on anything but a Volvo 70.

You can always paint it later if needed. Painting is relatively cheap.
Exactly - paint it years later when the anodizing is worn away

Never heard of anodizing over paint. You would have to strip it first and it would be very expensive.
It would probably be cheaper to buy a new extrusion.

I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.

Re: painted or anodized mast

I've had painted and anodized masts over the years. My first boat had an anodized mast and after 10 years it looked OK, but had its share of scratches and had a kind of cloudy look--not as sleek as when new. This mast was stored inside out of season.

My next boat--a gaff-rigged catboat--had a painted mast that I completelyrepainted at least once in the 16 years I had her. The area in contact with the gaff had be be repainted every year. Anodizing wouldn't have held up in the long term and there would have been no easy way to keep up with the gaff wear. That mast was painted with a one-part topsides paint.

My current boat is 23 years old and has an Awlgripped mast. It has been refurbished professionally once and is still looking good. The refurbishment included taking everything apart and reassembling the rig with care to insulate stainless hardware from the aluminum. It is showing minor bubbling in places but the scratches are minimal and you'd have to look carefully to see any compromises in the finish. BTW, my mast is in the weather year round.

Bottom line for me is that the Awlgrip finish is tops for cosmetics and is long-lasting enough that the cost to keep it up is reasonable. That said, if it were a workboat, I'd go for anodized and then cover it with a one-part paint when it got to looking ratty.

Re: painted or anodized mast

What about powder coating?
How does it hold up?
I was wondering about the powder coating on a mast and other sundry items. I know nearly all motorcycle frames are now powder coated, and they take a pretty good beating.

I doubt there are any ovens big enough to cook a mast. It takes 200 degrees C - not exactly like the hot rooms used for curing pre-pregs or baking car paint.

Booms, spreaders, spinnaker poles etc. - probably work quite well. It's tuff stuff.

Nothing takes a beating like a boat. Sometime I wonder how humans survive aboard. How, the yard tards are the most likely offenders, when they haul, launch, step masts, etc.

Even if it were possible and cost effective, it would eventually breach. Once it did, imagine how awful the peeling coating would look and it would be irreparable.
