The DMB is a 65-foot sailboat designed as a safe, comfortable,
fast and environmentally friendly vessel for research and
education. Its mission is to aid in seeking, teaching and
communicating scientific understanding of our oceans and atmosphere
for the benefit of society and the environment. She is USCG
rated for 49 passengers but we typically limit the number
of passengers to 35 for your comfort.
The DMB is designed for multiple uses. It will easily carry
research scientists and 5,000 pounds of their gear. Students
and teachers can be accommodated for daylong or extended trips.
Provision has been made for persons with disabilities.
The DMB is a mono-hull sailing vessel, 65 feet in length,
with 15 feet of beam, 8'3" of draft, and of 35,000 pounds
displacement. There are sleeping quarters for 12 passengers
and 2 crew in four staterooms and a common area. The DMB's
hull, deck, wheelhouse and bulkheads are bonded together into
a single structure; this is called monocoque construction.
The materials used are Baltek endgrain balsa-core planks combined
in a fiberglass reinforced "sandwich," the strongest
and most environmentally friendly materials and construction
method available today. A 100 horsepower diesel engine provides
enough auxiliary power to reach 12 knots. The range under
power alone is 1500 nautical miles. This speed and range is
greater than most motor-only research vessels of this size
and assures that schedules can be followed.
The DMB has many modern features that uniquely qualify it
as a 21st century sailing research vessel. It was designed
to be easily and inexpensively sailed with a minimum of effort.
Its hull and keel are highly evolved shapes, designed to provide
an easy, comfortable and efficient motion through the water.
The keel is a fin-bulb design, similar to those used in modern
racing boats, which places the center of gravity low and provides
increased stability as the boat heels. The cat-ketch rig,
with a sail area of 1,530 sq. ft., is innovative, simple and
effective. The tapered carbon fiber masts are free standing
and flex, changing the sail shape as the wind velocity changes.
The result is a rig that to a great degree adjusts itself
as conditions change. The rig absorbs changes in the wind
without transferring as much of those forces to the hull.
This smooth transfer of energy results in a smoother motion
through the water, reduced heel and no speed loss. Much less
effort is needed to operate this rig; one person can handle
it using two small winches. Plus, the reduced sail inventory,
elimination of standing rigging and reduction in other rigging
and winches lowers the operating costs. The cockpit is unusually
spacious with a door fitted at the transom. A Titanium A-Frame
is available for deployment. This area can be used to carry
research or school equipment such as a submersible, RIB, or
a flotilla of kayaks and canoes. The hold can be used to store
dive tanks, compressors or other equipment.
The DMB was designed to operate in a manner that has the lowest
possible negative impact on the environment. It is self-contained,
with no overboard pumping of waste. As a sailing vessel, it
can be operated in a quiet, non-contaminating way. It can
be maneuvered silently, holding station or peacefully following
observed subjects in a non-threatening way. Under sail, rolling
motion is reduced and engine odors are eliminated, reducing
the chance of seasickness and increasing the productivity
and enjoyment of the voyage. |
