In the last issue of Sea History (#153, p.
the weight and consequent intact,
damaged, and sailing stability characteristics of the vessel were of critical importance from the very beginning of the design and construction.
The shape of the hull and displacement characteristics, driven by the weight of the structure and appointments,
are critical factors ro get right from the beginning and follow throughout the build.
The weight of the ship, as well as positions of the centers of gravity, and construction of the vessel.
At each stage of construction advancement,
This was essential when it came rime ro move the ship from her build location in a parking lot to a place where she could be easily and safely lifted and gently placed in the water.
We knew precisely what her weight was at the time for moving/launching.
and the likely final weight when completed-placing her exactly on the designed B.otation lines.
One of the scenarios for launching the ship involved moving her overland along the San Diego waterfront and launching her by barge crane from a pier adjacent ro the Maritime Museum of San Diego.
A local tug service company generously offered the use of its barge crane for this delicate operation.
To verify our calculations and ensure the safety of the ship and equipment at time of launch, we had the ship physically weighed by a local house-moving company,
utilizing specialized hydraulic pressure sensing equipment.
Unfortunately, from the field the measured weight was misstated significantly ro the low side
The accurate weight of the vessel, together with our calculated weight for launch co ndition with all necessary crane rigging and support,
indicated that we would be too close ro the crane’s lift limits for reasonable comfort,
and thus we determi ned ro find a different solution for launching the ship.
Unfortunately, the combination of a misstated low weight and exceeding the safe weight limit on the barge crane with the actual weight somehow led to the false narrative that the ship was “too heavy,”
“heavier than expected,” or as in the Sea History notice “significantly heavier than first calculared”-none of which is true.
The actual solution ro moving the ship from her build site and to a launch area involved careful engineering and cooperation among many of San.
Diego’s finest maritime companies and was handled with the highest professionalism and minimal muss and fuss.
When launched, the ship B.oared at the draft marks as expected for the level of completion at the rime.
Bur we guess that this story is too bland for the average interested party.
and it is more fun to tell tales with more intrigue and less accuracy.
Thank you for allowing this expression of rhe true record.
