It's been awhile but when we were launching there, high tide was never a problem but low tide could get tricky at times. especially on the runs out to mission. You had to know where the channel was or you would end up grounded in the mud. Might be worth your while to feel it out sometime. On a related note, there are plans for a park with boat launch and parking just a little ways upstream by the city parks dpt. in the (hopefully near) future. smile Welcome to Marysville!
