The original mast extrusion is no longer available. As accidents happen,
people need new masts. Right now, I don't have a good answer for you, but
I hope that this page will collect enough information to help.
Gary Barker (Blarney, #563) reports, "Mast measurements

Cross section is 3.5 in. x 6 in. Extrusion is 5/32 in. thick."

We went to a Windjammers lecture to hear Bill Seifert and I was impressed enough to buy
the book on the spot. I've heard a lot of people talk about ways to improve a boat, but
I've never heard one person suggest so many good ideas that I hadn't considered. Part
of the charm is the specificity of the suggestions. Everyone says you should secure your

Besides modifications, the book also includes advice for operating offshore, cooking,
boat selection, dealing with bureaucracy, and more.
