M_Boats: M23 on Puget Sound?

Rick and I were out Sunday on the Puget Sound, and we saw a M23 with what looked like (through binoculars, from a distance, and under massive bouncing) a red stripe, but I don't see any 23s on the database listed as having a red stripe (and I don't remember enough details about the colors of the boats from the San Juans trip to know if what I was seeing was something other than a red stripe). We tried to catch up, but the 23 was going north headed across the ferry track that we had just crossed, so after a bunch of furious waving, we turned back south. Just curious whom we missed. -- Debora Eidolon M17, 635
