Container ships can be loaded to capacity either by volume or by weight. In the former, they load the maxiumum number of containers that the hold and deck have space for, while preserving visibility lines. In the latter they have loaded the maximum tonnage, even if there is space for more containers. Obviously the profitability of a given voyage depends on balancing the two, since empty containers don't pay.
This morning, June 29 both the departure and the arrival appeared to be well down on their draft marks, but possibly more room for containers.
ZIN Qingdao sailed from PSA Halifax Atlantic Hub for New York on the ZCA service from the Mediterranean.
The 39,906 gt, 50,689 dwt ship, built in 2006 by Dalian Industry Co in Dalian, China, appeared to be loaded to near capacity of 4250 TEU, with most stacks five boxes high, leaving maybe a few gaps in the deckload for more.
The inbound ship, which was to take its place at Pier 42, was very neatly levelled off on deck, but with stacks only four boxes high.
The ship caried the name Zim Ukrayina from 2009 to 2018, then briefy Bahia in 2018 when it became MP The Brown until 2021.
I can explain the significance of the latter name. One time investor / owners Mangrove Partners (MP), based in New York, named their seven ships after New England Patriots football players, one of whom was Troy Brown. Aside from the unusual names, Mangrove Partners ships also acquired notoriety because of the profit they turned when sold. Bought for $62 mn during the depressed market of 2017-18, six of the ships were sold for $368 mn in the 2021 high-demand post COVID era. MP The Brown was not included in that deal, but likely sold at a handsome profit too, as they were all sold to MSC.
