I spent 3 days sailing Lake Umatilla, Columbia River, June 2015, launching/parking at the Boardman Oregon boat ramp. It happened that I was between big winds, so this is when the winds are light in this area (rare).
Tom Luque and Andrew Linn crewed on Tom's WWP-19 "Jojoma" for the first leg of the Race to Alaska from Pt Townsend to Victoria BC. They both did write-ups of their adventure. It looks like it was a very interesting day for the two of them! Way
