Accommodations/Walkthrough
Finished in quality light satin Burmese teak, the salon features comfortable
off-white leather sofas, chairs, armchairs, and coffee table. A Burmese teak
dining table accommodates eight guests for formal dining. The forward salon has
twin marble topped Burmese wooden bars with bar stools which act as a divider
for the galley space. This area can flexibly accommodate family style relaxation
with the audio visual equipment. The aft deck has outdoor seating for al fresco
dining.
The
master stateroom has a queen sized bed, accompanied by a marble fitted en-suite
bathroom, decorated in highest quality teak of Burmese origin, plenty of
cupboards and storage, and brass portholes. The stateroom is equipped with an
audio system and air conditioning control panel. As a unique feature, the
overhead has a skylight affording the stateroom natural light and a view of the
sky, which also doubles as convenient safety access. Also equipped with
Raymarine multi repeater to see the wind speed, wind direction, depth, alarm,
boat speed, heading, etc.
In
addition, there are two twin staterooms for further accommodation requirements,
decorated to
equal
standard, each providing two single beds with en-suite marbled bathrooms, brass
portholes, and air conditioning control panels.
The
galley is complete with all quality appliances (refrigerator, freezer, oven,
cook tops, extractor fan, microwave, dishwasher) and fully marbled surfaces. The
laundry equipment is housed in a discreetcupboard adjoining the master and twin
cabins (washing machine and clothes dryer).
For
outdoor activities, GLOBE TROTTER offers an outside dining table with seating
for six, an R.I.B. tender with an outboard for trips ashore, and a beautiful
retracting swim platform controlled by a panel on the aft deck. The yacht has
abundant period features that include, but are not limited to; the Derrick
styled davit on the boat deck, brass cleats, brass retractable capstans, and
brass window frames. Teak chests for mooring lines ensure a tidy deck.

Hydrostatic Data
The
ATLANTIC 66 was not designed as a near shore cruiser that could run at 15 knots
when needed.
She has
a full displacement hull designed for only one thing, 9 knot displacement speeds
at
maximum
comfort and range in blue water situations.
Serious
blue water yachtsmen consider (Voyaging Under Power) by Captain Robert Beebe
their cruising bible. In his book three of the main calculations for the ideal
cruising yacht are
D/L
ratio,
A/Bratio,
S/L
ratio.
D/L
Ratio is the ratio of the displacement of the vessel to its length. Beebe
recommends a ratio of at least 270 for a 50' Ocean capable vessel. The ATR 66
has a ratio of 398.
A/B
Ratio measures the ratio of the side view of the vessel above the waterline to
the side view area below the waterline. Beebe recommends a ratio of 2.6 or
below. The ATR 66 has a ratio of 2.05.
S/L
Ratio is the ratio of speed to waterline length. The S/L Ratio is tightly tied
to the concept of hull speed. As a displacement boat moves through the water, it
creates a wave. The faster the hull moves, the longer the wave gets until the
length of the wave matches the waterline length of the vessel. At that point the
displacement hull has reached hull speed thus a longer hull has a higher hull
speed since it can go faster before the wave it creates matches the length of
the boat. Hull speed is reached at an S/L ratio of 1.34.
Bulbous
Bow
Anyone
who spends much time around large ships has noticed the bulb shaped protrusions
that are common on bows of large ships. To understand the purpose of the bulbous
bow, we have to briefly review the characteristics of a displacement hull as it
moves through the water.
Displacement hulls push water aside as they move. The water that is pushed aside
forms a wave that begins near the bow. The length of this wave is proportional
to the speed of the hull through the water the faster the hull moves, the
longer the bow wave. At some speed, the length of the bow wave increases to the
point that it matches the length of the hull, and the hull operates in the
trough of the wave, with a peak near the bow and another peak near the stern.
This speed is called the hull speed and it is approximately 1.34 times the
square root of the waterline length of the hull.
The
purpose of the bulbous bow is to change the nature of this bow wave to reduce
the drag it
induces
on the hull. The bulbous bow creates its own wave that is farther forward and
out of phase with the natural bow wave created by the hull, effectively
subtracting the normal bow wave add reducing its drag-inducing effect.
Clearly
the design of the Atlantic 66 conforms or exceeds to Beebe's ideal offshore
design for vessels.
She is
retro above the waterline but pretty modern below the waterline!
