I had the unfortunate experience of breaking upper (gaff) & lower (boom) spars and bending the mast in a "sunfish in the surf" expedition... I believe that I can buy stock aluminum tubing but wanted to confirm the dimensions. My measurements suggest both the sail spars are 1 1/2" outer diameter by 13'4" aluminum tubing with .065 wall width. My measurements for the mast are 2 1/4" diameter by 10' with the same .065 wall width. All seem to be clear annodized... ===> Can anyone confirm these dimensions? ===> Has anyone gone without annodized Aluminum or used a different coating" ===> What does the annodizing do?
