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
A race sponsored by the Port Townsend Pocket Yachters, Northwest Maritime Center, Small Craft Advisor Magazine, and others. You would probably enjoy the introductory video if nothing else. Race to Alaska
This is only to get the ball rolling for discussing this year's annual July 4th sail on the Columbia River. I have designated 4 days for this event this year but other sailors may want to shorten or lengthen the time of their participation as desired.
