Well daddle I still think it's doable. Maybe the 75 day boat was a
shallow draft, long keeled thingy that can only point 55 on a good day. Maybe he sailed into the high which can sit directly North of Hawaii. Maybe he tried it off season and got pounded. During summer a voyage of 40 - 60 days to
Seattle is quite realistic.
I was in Majuro in May 2007 and the trades were blowing 080 at 15 - nnnnniice ! The swells in Hawaii were around 10ft but by Majuro they were down to 4ft. The easiest
passage of my life was Hawaii - Majuro, 14 days of all downhill interspersed only with the occasional gybe. 1 day of no
wind + 1 day of high
wind, which was only 25. Eeeezzzzeeee ! ! !
Leave Majuro in May or June, set a nice comfy close reach angle of 50 or so and
head North on a lonnngg starboard dig ( Majuro is 7N ). The breeze should start to change around 35 - 40N allowing you to ease a little. By 45N you should be able to ease a lot and sail downhill for 20 -25 days aaallll the way to Seattle.
While I do not dispute your 75 day story kapena, there is an important piece missing from the puzzle. I agree that you might sit in Majuro for 2 months waiting for a ride in that direction.
