Father's Day Dive on the MT 6

Sunday, Peo Orvendal, Mark Tourtellot, Walter Jacard and Scott Christopher joined Mike Ferguson at Porthole Charters for a dive on the MT 6 (the Tacoma). This vessel rests upright at 200 fsw in Elliot Bay.

Scooter the wreck for 25 – 30 min


40-50 min


The Teams:

Peo and Mark

Walter and I


Larry Cleeton


Mike at Porthole

We all descended to 195 fsw together. There was no need to search for the wreck as Mike and Larry dropped the line in the perfect spot, which of course is close enough to see the wreck, yet far enough away as to cause zero damage to the site. Mark and Peo broke off to the starboard side, Walter and I crossed the ship and continued counter clockwise around it. Scootering this wreck allows you to see every inch of it. Visibility was stellar on the bottom. This is truly one of the best wrecks in our area. After circling the wreck a few times Walter and I decided to do a little penetration though an opening in the side of the wreck. Walter tied in a primary and secondary tie and we proceeded inside. There was just as much life on the inside of the wreck as the outside. We reached a point in the penetration where it would have been difficult to continue forward carrying deco bottles and scooters, so Walter signaled to exit. We exited the wreck, removed the ties, and continued to explore the exterior of site. At 30 minutes, we meet up with Mark and Peo and started the journey back to daylight. Larry met us about half way up and made certain we were squared away for the remainder of deco. The deco was pleasant, as the current was very light, the water was a few degrees warmer than the bottom, and the visibility was still great. We saw all the usually PNW life on the wreck. We observed lots of Rock Fish, a giant Ling Cod, and tons on invertebrate life. We all left the Mariana to spend the rest of the day with our families. Thanks to Mike for being a great captain and host, Larry for an awesome support role, and Mark, Peo, and Walter for being great teammates. Next up the AJ Fuller at 240 fsw in a few weeks.


Side Scan Imagery of the MT 6 (Former Ferry Tacoma) in Elliott Bay

Below are two side scan images of the MT 6 resting in 200fsw just of Salty's in Elliott Bay Seattle.  This wood barge is a fun and impressive dive.  Protected from current by its location deep in the bay it can be dove most days regardless of slack timing.  Considerations for this dive include the need for Coast Guard Permission and the fact that the Duwamish River dumps into Elliott Bay very close to this site.

John Sharps of Jaws Marine has an excellent accounting of the MT 6's history.











This images was taken aiming the side scan unit down over top of the barge.  Note the flat deck is intact in many areas.
