There's a lot to like about the Nautilus Explorer, but the hassles of
diving in US waters may be too great a reason to avoid her.
Scheduling this trip to dive California's Channel Islands in July was
remarkable for its difficulties, though I don't think the blame was the
boat's.  This is a Canadian-flagged vessel, and as such is restricted by
the American "Jones Act" from picking up and discharging
passengers at subsequent US ports.  We signed up with our local dive shop -
Pan Aqua in Manhattan - for a trip that was originally advertised as
boarding in Santa Barbara.  Sometime after making our deposit, we read on
the Nautilus Explorer website that we would board in San Diego, being
picked up at the airport at 2:00 PM on the day of departure.  Sometime
after that, we were reminded to bring our passports: when someone asked
"Why?" we learned that we would now board in Ensenada, Mexico,
and that pickup time was now 7:30 PM at a hotel near San Diego airport. 
That involved processing through immigration and customs at the Tijuana
border crossing, which required everyone to leave the bus with all their
luggage, and every bag was opened for a Mexican customs agent to run her
gloved hands over the contents, not really looking for anything, just going
through the motions.  This can take a long time, after which we had to drag
our gear back to the bus and restow it.  We did not reach the Nautilus
Explorer at her berth until 11:30 PM, at which time Mexican harbor
authorities outprocessed us since we would be leaving their waters the next
day.  Coming from the east coast, it was a long, long day.
At the end of the week we disembarked in Ensenada again, cleared (Mexican)
immigration and bused back to San Diego at noon.  A traffic jam in Tijuana
delayed us nearly three hours and had more than a few people nervously
looking at their watches, worried that they would miss their flights home. 
At the border, we had to offload all our luggage again, this time to drag
it nearly a block to the barrier and inspection by US immigration and
customs agents.  Once clear, another block was between us and where the
(empty) bus had moved to pick us up: nothing like dragging lots of scuba
gear two blocks on a sunny California day in July, and it was now rush hour
in San Diego.  It would have been nice to have avoided this type of
jerk-around, but as far as I know, there are no US-flagged dive boats of
the Nautilus Explorer's scale working the California coast.
The boat itself is nice, though with a few quirks.  The first thing I
noticed when boarding was that she lists a bit to starboard, but nobody
seems to know why.  She also normally works with a small boat (absent this
trip) that is pulled up onto the ramp in the stern.  This same ramp is used
for diver stations.  Unfortunately, the shelves for tanks and BCs are also
on the ramp and slope accordingly: once bungee cords are released it is not
unusual for a diver's rig to slide or fall over.  A metal bin below the
tank racks holds personal gear, but there are no plastic  bins for small
stuff: anything small can slide under the panels and be gone.  One
advantage, however, is that divers suit up standing: there are no benches
for sitting so you don't have to stand up again once you are ready to go
and collisions are surprisingly few.  A full-size dryer is mounted on the
dive deck and keeps divers well-supplied with warm towels between dives,
which is especially nice.  A hot water shower is available at the top of
the rack, too.  On the other hand, the camera table does not have an air
gun, which seems an odd oversight.  Drying space is awkward: one short rack
on the dive deck and a long bar at the top of the ladder to the second
deck, which means you are constantly ducking wet stuff.  Even more
problematic is that there is no head on the dive deck, which means you have
to strip down and use your own between dives, which seems contrary to
keeping wet gear out of the cabins.  One of the divemasters claimed that
the crew hosed down dive rigs with a freshwater hose every other night, but
I wasn't convinced they did it more than once (this doesn't mean they
We started off the first dive day at the (Mexican) Coronado Islands at a
couple of no-name dive sites.  For July, the water was cold and motivated
me to grab hood and gloves for the rest of the week.  The crew told me that
"La Nina" was pushing colder water north.  Between dives a
Federale boat approached and queried us, which made for an interesting
moment.  After three dives we motored north to San Diego to clear US
immigration and then proceed to Catalina.  On the second day we dove
various sites there amid the kelp and giant black sea bass, and then moved
overnight to San Miguel Island; four dives there and then another overnight
motor, this time to Ventura to again process in-and-out of US waters (that
damn Jones Act).  We cleared there mid-morning and moved toward Anacapa
Island.  Diving there was poor due to surge and poor visibility.  But from
there we moved to the Eureka oil platform where the visibility was
excellent and the encrusted understructure was just awesome.  Back to
Catalina for a few dives and a shore excursion for those who wanted it, and
then overnight to San Clemente Island.  The weather had been overcast most
of the week, but cleared this last day to give us great light into the kelp
forests.  A harbor seal approached us near the end of our second dive,
spending nearly fifteen minutes with us playing, and was the high point of
the week.
We had one of three larger cabins on the second deck; most guest quarters
are belowdecks.  The trade-off is more light and ease of egress versus
stability: Nautilus Explorer is a monohull and does roll a bit when
underway.  Linens are changed every three days; a good idea, but they
really ought to tell you this when you board.  There are insufficient hooks
in bathrooms to hang up towels to dry, anyway.  Cabin lights were
insufficient, and bathroom lights did not adequately illuminate the shower,
but you could make an argument that nobody really needs light in the shower
since by the time you are old enough to dive you should know where
everything is, anyway.
Ship power is 110v, American-style plugs in the cabins.  Cycles seems an
open question: the clock radio in our cabin kept inconsistent time.
Food was generally excellent, even vegetarian items prepared for my dive
buddy.  Warm breadstuffs and cookies were also shoved into us by the staff
between dives.  There is a bar on board and the boat follows the rule of
"first drink means you just made your last dive of the day;"
drinks are priced as you go.
The crew was terrific: generally well-qualified, helpful and pleasant.  The
only shortcoming here was that they needed a local divemaster on board:
they obviously didn't know many of the sites we dove.  Not surprising as
this boat does most of its work much farther north.  Overall, the boat is
well cared-for and its crew is obviously very fond of her.
