The last two dates are Saturdays. It's called the Hiram M. Chittenden Locks. As many of you know, a lock is just a big water elevator. When you go from Puget Sound to the Lake Washington Ship Canal, through Lake Union and into anchorage at Union Bay, you take the elevator up as much as 26 feet. When you return to Puget Sound, you take the elevator down more or less the same distance, depending upon tides.
Boats stage at the piers in front of the locks and watch for the green light.
The lockmaster gives traffic directions over a public address system. There are two locks. Both probably will be crowded on game day, so you should plan on taking at least 90 minutes to get through. Once through the locks, you'll sail through the 8-mile long Lake Washington Ship Canal, into Lake Union, through the Montlake Cut and into Union Bay. Union Bay is the shallow bay where you'll find mooring buoys and a float.
