Yeah so on a more serious note we went from Seattle to Blaine via Deception Pass and had calms a significant portion of the way, and no motor at the time. The calms were primarily between Skagit Bay and Cherry Pt. I imagine they're worse this time of year than when we went (late March last year).
Btw what is "the ditch"?
