Having sat here in Sequim listening to several days worth of NOAA's reports of 4'-6' wind waves on top of 13' / 10sec swells at the West Entrance to the Strait I have to say that I think some representative numbers and corresponding maneuvers would be very useful.
Also any suggestions on "reading" the conditions when on the water and assigning values to them would likewise be useful.
Awhile back Hardee and I took the J.C.Lately out beyond Dungeness onto the Strait and sampled some rollers I estimated (using Chapman's reference of waterline to eye-level baseline measurement) at about 4' maximum because when in the troughs the horizon just disappeared. The ride was quite smooth since the surface remained glassy so, presumably, the value for wind waves was about zero; neither of us had a good idea for how to determine the period of the waves. The ride was comfortable at about 10 kt although a little disconcerting since the traffic periodically disappeared with the horizon.
On the other hand I drove out to Sequim Bay yesterday to have a look at things during the time when the folks on Puget Sound were experiencing gusts to 60 kt. The waves were, of course, all wind waves and were (judging from their intersection with some pilings) probably not much over 2'-3' but many were breaking and somewhat disorderly. So I'd have to guess that the ride would not have been pleasant and, with a quartering wind, that threading the needle through the breakwater into the harbor would have been a challenge.
I would think that it's possible to build a matrix of sea characteristics (swell, chop, period, heading vs direction of sea) within which we could each determine our own comfort zone. And, now that I read this, I might as well wish for an advanced degree in statistical analysis, too.
