Dyna Rig Yacht Concept & Maltese Falcon Reality

Dyna Rig Yacht

Dyna Rig Yacht

The concept of the Dyna Rig yacht was developed in the 1960s by Wilhelm Prolss, a German naval architect, to provide increased propulsion for commercial ships in response to a projected energy crisis.  When the crisis did not materialize until the 1970s, the Dyna Rig yacht concept was once again brought back to life with further testing, however, no Dyna Rig yachts were ever built and eventually the idea was archived.

In essence, the Dyna Rig yacht would be fitted with a square rig system.  The mast would be completely free standing while the yards were to be tightly connected to the mast.  The most prominent difference from a standard square rig was that a Dyna Rig yacht had a designed curvature of the yards which was calculated at twelve percent of its cordage.

The sails on a Dyna Rig yacht were configured between the yards so when they were deployed they would stack upon one another with virtually no gaps in between which would enable the sails to act as if they were one.  When the sails were not in use they furl back into the mast.  Since there would be no rigging, the yards would be able to rotate without any restriction and in conjunction with the curvature and the uniformity of the sails, the Dyna Rig yacht was an unproven combination in aerodynamics.

Until 2001, that is.  American billionaire Tom Perkins commissioned “the world’s most spectacular sailing yacht” to be built.  Following the Dyna Rig yacht designs of Prolss, naval architect Gerard Dijkstra & Partners (Holland) and builders Perini Navi (Italy/Turkey), produced the statuesque Maltese Falcon in 2006. The luxury 290’ sailing yacht, which cost between a reported $150-300 million USD to build, features three twenty-storey tall carbon-fibre masts covered by 28,500 square feet of canvas.

The exterior/interior design of the Maltese Falcon was developed by Ken Freivokh Design (UK) and features accommodations for twelve that include one master cabin and five guest cabins, plus eight cabins for crew.  The modern spacious interior offers up a fully equipped gymnasium, plasma screen televisions and a Bang & Olufsen surround sound system throughout.  Extra amenities onboard the Maltese Falcon include four Laser sail boats, two 32’ Pascoe rigid inflatable tenders, a Castold 14’ jet tender, water skis, snorkel gear, and six sets of scuba diving gear.

Powered by two 1,800 HP Deutz diesel engines, the Maltese Falcon can attain a top speed of 24.9 knots, allowing the passengers and crew to enjoy smooth sailing all the way.  The ingenious Dyna Rig yacht design has enabled the Maltese Falcon to spend an estimated 55-60% of her time under sail cruising at a comfortable 20 knots during her first 72,000 nautical miles at sea.

With all of its success due to the Dyna Rig yacht design, Tom Perkins sold his beloved Maltese Falcon in August 2009 to an unknown, but obviously wealthy private buyer, for a reported $103 million USD.  The Maltese Falcon remains under both charter and full operations management by Burgess Yachts of the United Kingdom.

Wind Generators for your Yacht

By Tim Plaehn
December 9, 2009

For sailboats and sailing yachts, keeping the batteries charged is an important challenge. Wind generators for yachts have become a popular option to provide electrical power in an environmentally friendly manner. Sailboats, by definition, are subject to steady winds that can be used by wind generators to charge up the onboard batteries. Currently there is a good selection of options for someone looking for a wind generator yacht.

Wind generators for use on a yacht or sailboat should meet a certain set of criteria (from the Kiss Energy website):

Operate very quietly  -   Virtually corrosion proof     -   Simple to service  and parts are available worldwide   -  rugged enough to operate in a gale

Here is a list of companies and websites that provide generators for marine use:

Aerogen Wind Generators are produced in the UK and come in several sizes to produce either 12V or 24V power. They are manufactured by LVM, Ltd and subsidiary of ITT. Website.

Southwest Wind Power produces the AIR-X and AIR Breeze wind generators for marine applications. Here is the company’s webpage for these products.

Ampair MicroWind is another UK based company with a range of wind generator products for yachts. Website.

Also hailing from the UK, Duogen produces generators that can produce power from a towed in the water source or a wind turbine. Website.

Kiss Energy out of Trinidad has a single wind generator model available through distributors worldwide. Website.

Rutland windchargers are from UK based Marlec Renewable Power. The company provides a diverse range of products that appear to be very popular. Website.

Windbugger is no longer producing new turbines but it appears parts continue to be available.   The website is still up if you are looking for information.

A wind generator yacht should be chosen based on the type and duration of sailing and the onboard electrical and battery system. Prices vary quite a bit, but I would be most concerned with finding a dealer and installer who will ensure the new turbine functions properly (and can remedy any problems!).  Even if you are not in Australia, the Crystal Solar website has some interesting information on the different brands of wind turbines. An exerpt:

“Over the past 10 years I have sold only around 15 individual blades for Rutland and a single blade for an Aerogen 6. All the rutland blades were sold to cruisers as spares….I have sold no less than 950 sets of three blades for Air – that’s 2850 individual blades”

I have no recommendation for one brand over another; I do recommend however, that you do your own extensive research. The online sailing forums have terrific discussions on the various forms of power generation. If you do not already have one, a wind generator for your yacht may be just the ticket to provide a reliable source of non-polluting electrical power.

Sailing around the world on Sunlight

Nearly 500 years ago, Ferdinand Magellan led the first expedition to sail around the world. With wind and sails, the journey was certainly a green one.  Now a Swiss engineer wants to match the feat — with a catamaran called “Planet Solar,” powered entirely on the sun’s energy.

Earth Systems Science Series Part 2: Tracking Carbon Emissions

If the American Clean Energy and Security Act of 2009 works its way through the Senate and onto President Obama´s desk, it will mark a significant paradigm shift for the value we place on carbon emissions and uptake. As part of the developing legislation, large emitters would be required to pay for their emissions using a cap and trade scheme (explained here and here). For such a system to work, government regulator must have an accurate means of accounting for both carbon emissions and carbon storage and sequestration.

Calculating a Carbon Footprint

A carbon footprint is the greenhouse gas emissions produced by a person, organization, or vehicle… bascially, anything else that produces CO2 or methane gas while in operation.  With the rise in environmental awareness, new concepts are emerging onto the marketplace…

Calculating a boater’s footprint is quite easy.   
Simply follow the formula below (auto calculator will be released shortly):

(choose fuel type) (#gallons) x (lbs) = carbon footprint Marinefuel and TerraPass Cooperative

Science Reinforces Human Role as Climate Change Impacts Accelerate

A new report of scientific findings confirms not only that human activity is the primary cause of rising temperatures, but that climate change impacts are accelerating.

The compilation of peer-reviewed research includes evidence that melting rates for mountain glaciers around the world doubled between 2004 and 2006, and that more than 28,000 plant and animal species are changing habits due to new climatic conditions.

Earth Systems Science Series Part 1: NASA’s Earth Science Initiative

   The NASA Earth systems science initiative just entered its 20th year, and to mark the occasion, NASA held a symposium at the National Academy of Science to review some of the scientific accomplishments made possible through the endeavor. Over the course of the three day symposium, scientists presented their research and discussed the impact of the NASA earth systems science initiative on the current understanding for a wide range of social, scientific and economic issues.
