My Dad & his partner had the "Flirt" (Page 8 of the link) on San Francisco Bay in 1945. I remember many a rough windy day on it. IIRC, my Dad said it was originally Gaff rigged, later converted to a Marconi rig. Last time we saw it, in the early 70's, it was rotting away on a mooring in Richardson Bay, we thought for sure it was dead, glad it was restored/re-built.
