This is the missing ship last reported near the Bahamas: http://www.usatoday.com/story/news/nation/2015/10/03/cargo-ship-hurricane-joaquin-missing-coast-guard/73279228/?utm_source=feedblitz&utm_medium=FeedBlitzRss&utm_campaign=usatoday-newstopstories

Does anyone happen to know which one of her sisters is still sailing that I would have seen in Tacoma in early January?

Yes, a very interesting ship. FWIW, 53 foot trailers and containers are now the standard on the overburdened highways of the U.S. They replaced the 48 footers. About every year the trucking industry tries to have Congress approve even longer trailers and containers. The railroads also use 53 footers almost exclusively.

Welcome Victor! Very strange ship! BRGS

Barge or pier,there is no need to apologize.Your photo is very interesting.Thanks for the aclaration.I wonder if I should apologize for the irony.Best regards.

Hi Victor, vessel is not obstructed by pier! This part of one bunker barge :-)! I'm apologizing for this inconvenience, but our vessel been all the time far away from her on this pier.

Yes Pieter you are right!
I saw that this vessel sailing between USA and Puerto Rico only! And whats makes me surprised - I saw "new" types of containers - 48' and 53' which been carried from this vessel and some other which sailing only between USA and Puerto Rico.
BRGS.

Be careful.David_s could be watching.Ship obstructed by pier hehehe

When I saw this vessel I was surprised. Very strange hull as per me! But unfortunately the port security(on the quay) didn't allowed me to approach this vessel never mind that our ship was ahead of her.

Resembles an Aircraft Carrier designed hull.
