PNW Shore Dives

PB4Y Privateer

By | Dive Sites | No Comments

One of my favorite local tech dives is the PB4Y Privateer in Lake Washington, which I affectionately call just “the bomber”. It sits in roughly 150′ and is only about a 15-17 minute scooter ride from Warren G Magnuson Park.

This is NOT a tech-reational dive, nor one I’d do on deep air. The lake is dark, not like a night dive… like I put a bag over your head. This tends to increase narcosis greatly ūüôā

Additionally the “bottom” of the lake is very fine grained silt. If you manage to kick it up (or lawn dart into it from a boat), plan on the silt cloud obscuring visibility for quite some time (easily¬†an hour +).

The entrance is just North of the boat ramp (the next turn in the road).

Here is a typical dive profile diving the wreck from shore. This is a CCR profile, on doubles I would dive 21/35 + 50% for deco.

There is a ton of great info and videos available from local wreck divers on the PB4Y:

As always with any dives: be safe, be prepared and don’t dive beyond your limits.
