Peavine Pass 2
Open the map ↗

Peavine Pass separates Blakely Island from Obstruction Island. It's described as safer and straighter than nearby Obstruction Pass, with a deeper midchannel — about 36 feet at the narrowest point, which is a bit over 200 yards wide.

Timing

The current here runs about as strong as Obstruction Pass next door — up to 5.5 to 6.5 knots at times — with heavy rips building on the east side of Obstruction Island close by. Time your transit the same way you would for Obstruction Pass.

Local magnetic disturbance

Peavine Pass, safer and straighter than Obstruction Pass, separates Blakely Island from Obstruction Island. The pass is a little over 200 yards wide at its narrowest part, and in midchannel the least depth is 6 fathoms. Peavine Pass Light 1, on the southwest point of Obstruction Island, marks the west entrance to the pass. Spindle Rock, marked by a daybeacon, lies about 0.2 mile offshore from Blakely Island at the east entrance to Peavine Pass.

Currents

The currents through Obstruction and Peavine Passes have estimated velocities of 5.5 to 6.5 knots at times. Heavy tide rips occur east of Obstruction Island.

Blakely Island, east of Lopez and Shaw Islands, is privately owned and maintained but open to the public. At its north end, bordering on Peavine Pass, is a small-craft basin and channel. About 65 berths are at the cove dock and inside the basin. An airplane landing strip and lodging are nearby. Gasoline, diesel fuel, water, ice and some marine supplies are available.
