You aren't going to make it from A-town to the locks in one day unless you can time it to ride some big currents. Fastest I've ever made the trip from Shilshole to the south end of Lopez is 9 hours and that was taking advantage of a big ebb to Pt. T and then a flood to Cattle Pass (34' boat). Plan on one full weekend (overnight at Langley?) to get it down there and then do your swap the next. You do not want to PLAN to be traveling in the dark at this time of year. As others have mentioned there is more wood out there right now than I have ever seen, and a lot of it is partially waterlogged making it very hard to see and very dangerous, even in daylight. Good luck.
