Alum highway pole for mast
 
Mast is 12" tapering to 8 and is 5/16" thick. Is this a good idea for a mast. Boat is 50' and steel so I don't know if its too heavy for the boat. Do they generally use good alloys in these poles? Just curious no plans to use. Couldn't find anything on search but I can't string words together properly I guess.

how do you plan to run the mainsail up the mast? hoops?
what do you plan to do with the cantilevered mercury light at the top and/or any attached signage?

How do you plan to cut it down and haul it away from the off-ramp without anyone noticing?

Now tell me why I should take this post seriously when I said I was just curious and had no plans to use one?

Why should I take your question seriously when you say you are just curious and have no plans to use one? :)

The first part of my reply to your question is the part you should take seriously. How would you plan to attach the main to your highway dept. supplied mast?

I don't know much about how masts are constructed, and even less about highway poles. But I would suspect that there's a reason why masts are generally more rectangular in cross section, as opposed to round like a highway pole. Would the round pole be more susceptible to bending or breaking when the forestay or backstay tension is adjusted?

PLENTY OF CATBOATS have freestanding aluminum masts that are in fact just fancy light poles

You would just need to see how close it to one of the catboats in current USE

Its really no different that screwing on a sail track on any other mast

A local boatbuilder, with much the same type of philosophy as our own Brent Swain, used to write a column on economy boatbuilding in Pacific Yachting back in the heyday of home building. He advocated this very thing - the light poles were MUCH cheaper than mast extrusions since they were produced in such huge volumes.

He simply screwed or riveted an external track on them and used sail slugs.

Personally I'd go for a round one, not one of the faceted ones. :D

Being the traditional sailor that I am, I much prefer a old
wooden telephone pole as a mast as they come with spike
steps to climb up and set the sails and have already in place
yards, and if lucky they may still have some old telephone wires to be used as braces.
