Florida Clean Marinas Mapped by Green Boating

Greenboating.blogspot.com has recently added an embeded Google Map to our site with the locations of all the marinas and boatyards designated as 'clean' by the Florida Department of Environmental Protection. We hope this is a useful tool to those who wish to patronize clean and green marinas in the beautiful waters of Florida.

Solar / Human Powered Green Boat Design

A French graphic designer named Jonathan Mahieddine has designed a boat which can be powered by solar or human power. He has taken the classic design of the paddle boat to another level by providing a sunning deck and a cockpit shaded by solar panels. While this design may not be practical for most, it would sure make for some clean green boating which would have very little impact on the environment.

Ballast-Free Cargo Ship Design

Researchers at the University of Michigan are developing a new design for cargo ships which could eliminate the need for ballast tanks. Ballast tanks are cited as environmental hazards as they often carry sealife in conjunction with water which is dumped in foreign ports. Ships take on ballast water for stability when they're not carrying cargo. They discharge ballast when they load freight, expelling tons of water and many invasive species such as the infamous zebra musscle.While Congress is considering costly legislation for tankers, the new design would eliminate the threat altogether.

The ballast-free ships have a constant flow of local seawater through a network of large pipes, called trunks, that runs from the bow to the stern, below the waterline, much like a submarine.

Not only would the newer design protect against invasive species, but researchers found it had an unexpected bonus; it requires 7.3 percent less power to propel the ship. The improvement is due mostly from water being expelled from the stern-end of the trunks into the propeller, allowing the ship to operate more efficiently.

Researchers concluded that the new design would result in a net capital-cost savings of about $540,000 per ship. Combined with the expected fuel savings, total cargo transport costs would be cut by $2.55 per metric ton.

International Association of Independent Tanker Owners Recommends Cleaner Fuel Mandates

INTERTANKO, the International Association of Independent Tanker Owners, is recommending emissions cuts for tanker ships. They have proposed a recommendation to revise MARPOL standards to bring shipping industry in line with other transportation emission standards. They are recommending the global use of Marine Diesel Oil (MDO) with specifications on its formula to produce a cleaner fuel. For more on this subject you can read the report here.

Suntory Mermaid II Uses Ocean Waves to Power Green Boat

The modern day champion of green boating Kenchich Horie has set off across the Pacific on another one of his legendary journeys to provide inspiration and scientific credence to his newest vessel's innovative design. The Suntory Mermaid II is powered by ocean waves. Fins at the front of the boat generate thrust by absorbing energy from motion of the ocean. As the fins absorb the energy they create a kicking action which increases speed and decreases the pitching of the boat.

The 9.5 meter 3 ton Suntory Mermaid II used recycled aluminum to create the unique aluminum alloy (A5083) that makes up its only 3mm thick hull. The boat is equipped with solar panels to provide electricity, and a sail and outboard in case of emergencies.

In 1996 Horie sailed the "MALT'S Mermaid" a solar powered boat built from recycled beer cans, from Ecuador to Tokyo.

In 1999 he sailed across the Pacific in the "MALT'S Mermaid II" a Catamaran built from beer kegs.

In 2002 he again crossed the pacific, this time in a boat made from recycled whiskey barrels.

His latest mission will take him a distance of 6,000 km from Japan to Hawaii. He will depart sometime in May of 2008. It is estimated the trip will take him two and a half months. Progress of the voyage may be tracked on his website.

Lagoon 420 Catamaran Awarded Mansura Perpetual Challenge Trophy

The Mansura Perpetual Challenge Trophy has been awarded to the Lagoon 420. The Mansura Trophy is the prize for the ecological design competition given by the Royal Thames Yacht Club.

The trophy was presented by the Duke of Edinburgh for leading the industry in green boating design. Over 70 of the Catamarans were sold in 2007, proving the design is commercially viable as well.
