I believe the Montgomery boat which sailed to Hawaii was an M15. I'm not aware of a 17.
Regarding sailing conditions for the M15. This morning I sailed "Really" from Coyote Point to Redwood City. This is a 14 mile trip on San Francisco Bay. There's a high pressure area to the southeast which was supposed to make this a most pleasant warm weather sailing experience because of a flood tide with 2.5 knots under the San Mateo Bridge. However, a new weather report had small craft warnings for the bay in the afternoon. There was fog off to the northwest. I left at 9am with 12 knot winds out of the nnw. And big wave action. It must have been blowing last night. I sailed with a 36sf, 4.5 ounce jib and a full main. I was flying. Once I got under the San Mateo bridge it became pleasant but at about 10:45am it started blowing over 15+ knots. Because of the wave action I put one reef in the main. It wasn't enough. I lowered the jib and sailed under control to
the Redwood Creek launch ramp.
I consider San Francisco Bay a marginal place to sail the M15 under these conditions because of all the variables and being on big water with no assistance nearby. For many years I sailed a Pearson Electric and a Cal 20 in the same area and I had few concerns because of the deeper keels and being heavier boats. Now - it's different. You have to realize your limitations and the boats limitations.
