Tim,
"Oh, BTW, I also see in your photos that you have black spars, as does The Red Witch. Haven't seen many DS's with them. Do you know if they were black originally?"
I'd guess that they were. The boat is a 1980 and the mast is a Dwyer DM-284. The black looks like anodizing, not paint. And they do get toasty in direct sunlight.
