aluminum pole thickness vs CF

[asdf777]

What's a rule of thumb for converting aluminum mast thickness into carbon fiber?

I'd like to build a CF radar pole - 2 72" parts joined with a ferrule. I've seen aluminum poles for radar from Edson 1/8" thick (for deck mounting), 2 3/8" OD, 90" long.

What would an equivalent be in CF?

What if I pass it through the deck and glass it to the hull?

CF options for wall thickness are either 1/8" or 1/16", pretty much any diameter.

Many thanks!
