Hi Justin,
My last boat was a Westsail 32 … in The Bay Area as well , that I was planning to convert to a single masted junk using Arne's plan.
I searched high and low on the West Coast for an affordable way to make , or purchase a wooden mast . I looked for wrecked boats , telephone poles and even researched cutting down my own tree!!! …In the end I decided I would use a tapered Aluminum Flagpole. The cost for the size I needed (I forget the exact specs) was approximately $4500. …just for the pole.
One place you could TRY … is The Napa Marina. They had a few old wood masts that they were selling. And, if I remember correctly (about a year and a half ago) they had one that was very close in size to what would be needed for a Westsail 32. It was an old solid wood mast…and it was MASSIVE.
In the end , and before converting , I decided that for me ….The Westsail 32 was too big.
She is still one of my favorite boats …and I would love to see her junk rigged! Good luck.
I may have some notes and plans lying around. Feel free to message or email me if you have any questions.
