Found another Redwing for sale on craig's list in Boston (thank you, Google Alert).
It looks like it needs a lot of soap and water, sandpaper, and wax, but damn it's pretty! Redwing is a 1970 and so is this one. I emailed the seller to see what the hull # is, hoping that it's the brother to my own! How cool would that be?
I like the blue hull and the name is pretty good, too.
