Lake Washington PBM Mariner

Notice

Unfortunately, the old adage "you snooze, you lose" holds true here. If you haven't dove this site already, it's too late. According to reports, on Saturday, September 28th, 1996, the U.S. Navy raised this wreck from the lake and therefore there isn't a dive site here any longer.

10-10-96 UPDATE

According to the Eric's SCUBA page Boeing field informant John N. Otakie (john.n.otakie@boeing.com): KIRO news at 10 had a fairly long report last night on the PBM salvage. It turns out that the Navy has been unable to get the plane un-stuck from the bottom, and has finally decided to give up.

Dive site again!

The Navy did bring up a few pieces which they are going to keep. The report also said that they would make the plane "safe for sport divers" before they left (whatever that means).

Description

The Martin PBM Mariner was an old seaplane (flying boat) about the size of a 737. There are only two known PBM's in existence. One is in museum down in Pensacola, and one is upside down in 70' of water at the bottom of Lake Washington. There's about 10' of mud and silt coating most of the wreck, so don't expect to see the wings.

Location

Parker's Comments

You are a better person than I am if you can burn a tank of gas on this dive site. Basically, because the plane is upside down and partialy sunk, the exposed hull is about as large as a 737. You should be able to peek in the old gun mounts, and cargo doors, see some of the props, and pontoons. Trust me, when I say that you'll be hard pressed to spend lots of time looking at this plane. It sounds really cool, but was a major disappointment. Yawn. I give this site one Thumb Down on the Parker Scale _only_ because it really is not too impressive.

Eric's Comments

I thought this was really really neat, but it does only take 15 minutes to see pretty much everything.

Here's a list of everything to see on this wreck:

If I was to do it again, I'd set up my gear different so I could take just my pony bottle and penetrate it.

That's about it. I give it one Thumb Up on the Eric scale. A must-do once dive, but doubtful if I'll do it again. Return to PBM-5 Site Copyright-Michael Parker.
