< WOW! A 140' trawler is an awful lot  of boat for 2 people. Surely
they must
have a crew. >

Big boats aren't that much harder to handle with two than a small boat,
just takes a bit more coordination and pre-planning.  My wife and I
cruise our 60' by ourselves, my 75 year old parents cruised their 60'
by them selves, I did a salvage with my 80' Dutch fishing trawler where
a friend and I steamed 150 miles out in the ocean, hooked up to an
eighty foot derrick barge and towed it home.

The 140' probably worked with a crew of five or six, one person in the
pilothouse, one "engineer", and the rest for when they were fishing;
cut out the fishing part and, other than docking, you need about two
people.  Okay, it would be nice to have a full time cook, which I did
when I brought my 60' down from Nova Scotia; stood the odd watch, but
primarily kept us full of good food.

other than docking, you need about two people.

In the open ocean, it doesn't take much to keep a
functioning boat headed in the right direction. The
problem is indeed close quarters, logistics, and
mechanical aptitude. Large boats often have multiple
electrical systems (12VDC, 24VDC, 120VAC, 240VDC,
sometimes 3-phase). Sophisticated hydraulic systems
with valve farms that resemble a nuclear reactor.
Shafts, couplings, steering linkages, etc are all
designed differently and require different tools and
knowledge - along with brute strength to handle. There
are lube-oil reservoirs and centrifuges. Multiple
generators and massive electrical transfer panels.
Head systems are typically different. A/C and heating
may be much larger. Even fresh water pumps are
different on large boats. This is all special
knowledge that isn't acquired at a 2-day diesel engine
seminar.

Depending upon configuration of the boat, docking may
be a realy challenge - an 80-foot sport fisher has
great access in/out of the cockpit. But a motoryacht
style boat may need the companionway steps lowered in
many instances - it helps to have a nimble deckhand
(or two) who can scramble around.

And that's not to mention any differences in USCG
requirements (like lights). When the boat is in top
condition and everything is working well, 2 people can
easily run it (though they had best be
near-professional crewmen), perhaps even dock it in
the right conditions and location. But how often are
the stars lined-up so perfectly?

I heard a knowledgeable boater observe a long time ago
that 70-foot yachts are awkward - too small for
professional crew, too large for the average couple to
operate comfortably. While bow/stern thrusters and
electronic navigation systems have helped, running a
70-footer is not trivial.
