I learned what windsurfing is at Elliott Bay, off the rocks near what is now the Olympic Sculpture Park, in the late 1980s. Then on the Clatskanie. Then in the Columbia Gorge near Hood River, which is where I really learned what windsurfing is. The Seattle waterfront has changed since then — the sculpture park did not exist, the cruise terminal was a different size, the Olympic Sculpture Park was an industrial site, the waterfront streetcar was still running on the original 1982 route — but the wind from the northwest still builds in the afternoon and the Olympic Mountains still fill the western horizon at sunset from anywhere west of Queen Anne.
Most people don’t think of Seattle as a sailing city. They think of coffee, rain, and technology companies. Sailors think of Shilshole Bay Marina — 1,400 slips on the Ballard waterfront, the Ballard Locks a mile away, Puget Sound opening up to the southwest, and the Olympics turning pink at sunset from the fuel dock.
This is the working guide.
What Seattle is, geographically
Seattle is the largest sailing hub on the US Pacific Coast north of San Francisco. The city’s geography is unusual: it sits between two lake systems — Lake Union and Lake Washington — connected to Puget Sound through the Lake Washington Ship Canal and the Hiram M. Chittenden Locks. Boats based on the lakes pass through the locks to reach salt water. Boats based at Shilshole are already in salt water, with open Puget Sound 5 minutes from the slip.
The result is a two-zone sailing infrastructure: protected freshwater sailing on the lakes for beginners and day-sailers, and the full breadth of Puget Sound for boats that have made the locks transit. Both are within the city limits. Neither requires driving to the water.
Shilshole Bay Marina
Operated by the Port of Seattle, Shilshole Bay Marina is where most Seattle sailing happens. The marina’s 1,400 slips occupy the Ballard waterfront between the locks outlet and Golden Gardens Park — a location that puts you at the mouth of Salmon Bay with Puget Sound immediately to the southwest.
The marina infrastructure is complete: fuel dock (diesel and gas), pump-out, haul-out, showers, laundry, chandlery, Anthony’s HomePort restaurant overlooking the docks. 120 transient slips are available on a first-come, first-served basis. The Corinthian Yacht Club and Seattle Sailing Club are both based here; several ASA-certified sailing schools use Shilshole as their home base.
From a slip at Shilshole, a day sail to Blake Island takes under two hours. Bainbridge Island’s Eagle Harbor is 12 nautical miles. Kingston is 14. Poulsbo — up Liberty Bay into the Kitsap Peninsula — is 20. The San Juan Islands are 65 nautical miles, typically a day-and-a-half run through Admiralty Inlet and the Strait of Juan de Fuca.
The Ballard Locks
The Hiram M. Chittenden Locks — universally called the Ballard Locks — are the passage between Lake Union and Puget Sound. A 26-foot lift in a single chamber, operational around the clock, free to use, and one of the more singular urban experiences available to a boat crew in the United States. Approximately 50,000 vessels lock through every year; on a sunny summer Saturday the wait is 30–60 minutes; on a Tuesday in February it is essentially zero.
Procedure. Call the lockmaster on VHF 16 as you approach from either direction. Wait for the signal — green light means proceed; red means wait. Enter the chamber and secure lines to the floating guide walls (they rise and fall with the water). Wait 10–15 minutes while the water level adjusts. Motor out into Salmon Bay on the salt side or Lake Union on the fresh side. The watching crowd on the observation platforms above is an invariable feature; the lockmaster staff are professional and efficient with mixed traffic of commercial vessels, recreational boats, and kayaks.
For sailors based on Lake Union or Lake Washington, the locks transit is the gateway to everything. Twenty minutes start to finish at slow speed. The fish ladder adjacent to the locks — built for salmon returning from Puget Sound to spawn in Lake Washington — is worth a look while waiting.
Sailing conditions from Seattle
Puget Sound from Shilshole offers a range of conditions depending on direction and season.
Northwest of the marina is open Puget Sound between Shilshole and Bainbridge Island, with the shipping lanes to the north and the ferry routes crossing at regular intervals. The prevailing summer afternoon wind comes from the northwest, building from flat calm in the morning to 10–18 knots by mid-afternoon. This is the reliable sailing window: leave Shilshole around noon, get the wind by 1 pm, sail across to Bainbridge or back.
South toward Elliott Bay and downtown is the stretch of water in front of the Seattle waterfront. Washington State Ferries run regular routes through this area — Bainbridge, Bremerton, Kingston. Give them a wide berth, especially the large vessels on the Bainbridge route. The skyline sailing here — downtown Seattle to port, the ferry wake, the Olympics to the west — is the postcard view that most people associate with Seattle sailing.
Currents. Puget Sound is a tidal estuary with currents that run significantly in the main channels. The current in Colvos Passage and Admiralty Inlet runs 2–3 knots; in smaller channels like Rich Passage near Bremerton, 4 knots. For day sailing around Seattle proper, currents are manageable. For passages north toward the San Juans, study the tide tables for Admiralty Inlet — timing the transit through the Inlet near the flood gives you a free 1–2 knot push northward. See Tides and Currents in the PNW for the working framework.
Wind shadows. The Olympic and Cascade mountain ranges create variable and localised wind patterns. Hood Canal directly west of the southern Sound can be dead calm when Shilshole is doing 15. Rich Passage between Bainbridge and the Kitsap Peninsula often has different conditions than the main Sound. Local knowledge develops quickly; after a season of sailing from Seattle, you know where the wind tends to be and where it tends to disappear.
Day-sail destinations
Blake Island State Park (9 nm). The classic Seattle day sail. Blake Island sits in the middle of Puget Sound southwest of the city, visible from Shilshole on a clear day. A state park covers the entire island: forest trails, a sand beach, and mooring buoys in the protected cove on the northeast shore. On a summer weekend afternoon, 20–30 boats moor here; on a Tuesday in June, you may be alone. Mooring buoys are self-service ($20/night via the Boater’s Pass app or an honour box ashore). No vehicles reach the island; everything arrives by water.
Bainbridge Island — Eagle Harbor (12 nm). Winslow Wharf Marina is the transient facility on the western shore. Bainbridge Island town (Winslow) is a 5-minute walk — coffee shops, restaurants, bakeries, a bookstore. The Bainbridge Island Museum of Art is free. The ferry back to Seattle takes 35 minutes if you want to leave the boat and cross as a foot passenger. Eagle Harbor has anchoring room in 20–30 ft east of the marina.
Kingston (14 nm). Port of Kingston public dock on the Kitsap Peninsula’s east shore. A small pleasant town with a grocery store and a pub. The Kingston–Edmonds ferry creates regular traffic in the approach; stay clear of the ferry lane.
Poulsbo (20 nm via Liberty Bay). Liberty Bay leads north from the Sound to Poulsbo, a Scandinavian-heritage town with a strong nautical character, good provisioning, a waterfront park, and Norwegian-themed bakeries that are worth the 20-mile sail on their own. The marina has transient slips.
Learning to sail in Seattle
Seattle has the highest density of sailing instruction on the US Pacific Coast. ASA-certified schools operate from both Shilshole and Lake Union, with the bulk of activity running April through September. The first ASA 101 (Basic Keelboat) course is typically a long weekend; the full ASA 101 / 103 / 104 sequence to bareboat-eligible runs over a season at most schools.

Navigation notes
VHF. Channel 16 underway. Puget Sound Vessel Traffic Service (Seattle) on VHF 14 — monitor for commercial traffic.
Locks. Approach on VHF 16, call Ballard Lock Master. Open 24 hours. Avoid peak summer weekend midday periods if possible (30+ minute wait).
Ferries. Washington State Ferries are constrained-by-draft and constrained-by-schedule vessels. Treat them as having effective right-of-way. The Bainbridge route crosses the main sailing area from Seattle; the Kingston route crosses further north. AIS is useful for tracking ferry positions.
Charts. NOAA Chart 18449 (Puget Sound — Northern Part) covers Seattle to Port Townsend. Chart 18450 covers the approaches to Seattle.
Fuel. Shilshole Bay Marina fuel dock — diesel and gas. Open daily. Call ahead on busy summer weekends.
The bigger picture
Seattle sailing does not end at Puget Sound. The city is the staging point for the entire PNW cruising range — the San Juan Islands 65 miles north, the Gulf Islands and BC beyond, Desolation Sound another 120 miles up the coast. Most boats making these passages start from Shilshole, transit Admiralty Inlet on the flood, cross the Strait of Juan de Fuca, and arrive in the San Juans in time for the first evening at anchor.
For an extended season, British Columbia becomes the destination — up through the Gulf Islands, north through Dodd Narrows, across the Strait of Georgia to Desolation Sound and beyond. The passage from Shilshole to Prideaux Haven in Desolation Sound is approximately 180 nautical miles — a 3-to-4-day cruise that represents the aspirational trip for most Seattle sailors.
It begins at the locks. It begins at Shilshole. It begins in Seattle.
