Boaters born prior to January 01, 1955 are exempt from the education requirements , there are some other exemptions for Licensed Coast Guard Masters and a few other classes. However taking a Safe Boating class is still a safe idea, learn early avoid the rush.

Anchorage In Seattle


Short-term anchorage is approved in Andrews Bay on Lake Washington. The approved area is defined by two buoys marked with “A” indicating the northwest and southwest corners of the anchorage zone. Shore markers note the northeast and southeast corners. Anchorage is limited ONLY to this area.

A 72-hour maximum stay within any seven-day period is permitted.

Lakewood Moorage, located northwest of the anchorage area, has a small store with marine supplies and snacks.

This area has a maximum speed of 3 knots noted by buoys. The City of Seattle has established a 7 Knot speed limit in other areas within 100 yards from shorelines, piers, fixed structures and restricted areas.

    Mike,
    Wondering if you know if it’s ok to tie up a dingy at the waterfront park by the aquarium. There are a ton of ladders on the pier going to the water, and it seems like it’d be easy to tie up a dingy for a short visit, to use the head, or grab a quick bite to eat at Ivars.
