About 6 years ago, my FIL, a friend, and I took a 37' Aft Cabin from the tri-cities in central Washington through the Columbia bar, then north along the coast of Washington, and east along Juan de Fuca to Anacortes, WA. We locked through 4 locks on the Columbia and overnighted in Hammond, WA at the mouth of the Columbia.
For several months I had been researching the "Graveyard of the Pacific." The guy who voluntarily opened his fuel dock early on the morning we planned to cross the bar said we had about an hour on each side of slack tide to make a comfortable crossing. After contacting the CG and getting the weather report, we hit it right at slack.
We had no problem crossing the bar, and a manageable roller coaster ride north along the coast of Washington.
The 5 day adventure was highlighted by coming upon a pod of Orcas along Juan de Fuca. The only boat within sight, we shut down and watched them from within spitting distance for about an hour.
