Petrochemical Free Cruising

Last month at the Wooden Boat Festival in Port Townsend I attended an interesting presentation by Capt. Peter Wilcox, Master Mariner and President of Columbia Riverkeeper. His subject was "NOAAs Green Ships Show the Way for Northwest Boaters", subtitled "Long-term test results of 100% biodiesel and biolubricants, state of the art electric power and the future of low impact, low carbon boating".

Capt. Wilcox started by detailing what the effect is on the oceans and their inhabitants from the acidifying effects of the carbon dioxide produced by burning fossil fuels. Most of this carbon dioxide ends up in the ocean either directly or via rivers. This upsets the balance of nutrients, oxygen and clean water that most marine life needs to survive. Some of that marine life is under threat of extinction.

in 2009 he launched the motor-sailer "Ama Natura" for cruising and exploring the inside passage, built for him by Northwest School of Wooden Boatbuilding. His boat was equipped to operate totally free from petroleum derived products. He followed the example and practices developed by NOAA for their fleet of green ships on the Great Lakes. NOAA have also assisted in the conversion of other vessels and the program now covers more than 200 NOAA and commercial vessels across the USA.

The NOAA green ships program was initiated in 1999, through the NOAA Great Lakes Environmental Research Laboratory (GLERL). Their vessels run on B100, biodiesel derived 100% from soy, a renewable energy source. In addition to the fuel, all of the lubrication and hydraulic products used on these vessels are plant-derived, from soy, rapeseed and canola oils.

Benefits that NOAA has seen from this program are numerous.

 Environmental & Social Benefits
? Decreases emissions of fossil fuels that contribute to climate change and air pollution
? Lessens risk of environmental harm in the event of a fuel spill
? Reduces dependence on imported oil
? Supports agriculture and the U.S. economy
Operational Benefits
? Improves engine performance
? Extends engine life
? Reduces need for engine maintenance due to cleaning properties of biodiesel
? Reduces operating and maintenance costs by 20-40% vs. petroleum-based fuels
Human Health Benefits
? Reduces exposure to harmful and cancer-causing chemicals
? Reduces seasickness due to less offensive odor

Biodiesel is cleaner than petroleum-based diesel, which is behind many of the benefits. These show in longer lifespan of injectors, fuel pumps and filters, also in reduced or disappearing cleaning costs for tanks, fuel lines and other components of the fuel system.

The emissions reductions of biodiesel compared with diesel, as reported by NOAA, are impressive.
? Total unburned hydrocarbons -77%
? Carbon monoxide -48%
? Particulate matter -59%
? Nitrogen oxide -7%
? Sulfates -74%
? Polycyclic aromatic hydrocarbon -66%

Biodiesel can be made from many plant sources, so can be adapted to the most suitable renewable crop or waste material. Used cooking oil can also be filtered and reprocessed to produce biodiesel, for a very cost-effective fuel. GLERL has seen a 20-40% reduction in operating costs on its fleet since converting to biodiesel and other bio products.

For more information on the NOAA program, read the NOAA Green Ships Initiative.

Biodiesels continue to be developed. Second generation formulations offer longer stability, higher octane ratings and lower waste. Biolubricants are also improving, allowing 100% improvement in oil life.

The NOAA clean ships program appears to be a good one, with major long-term benefits for the world in general and for boaters in particular.

Cruising Tug

Peter Leenhouts of the Northwest School of Wooden Boatbuilding, Port Hadlock which is located on Washington States Olympic Peninsula, northwest of Seattle wrote with some details of a cruising tug which was launched in August of 2012.


Tug boat derived pleasure boats are popular in the US but very rare in Europe, perhaps that comment will elicit a flood of emails from European owners, if so please send photos and details wed live to feature more examples.


Back to the boat in question, it was designed by an American, H.C. Hanson in 1957 for the US Forest Service as a Scalers Boat. Scalers determine the amount of board feet of lumber in each log cut by a timber crew.

Three boats were built commercially in the mid-1950s to this design for the US Forest Service for use in the Pacific Northwest. Construction on this latest example began in 2010 and finished in 2012, with the schools classes of 2010, 2011 and 2012 all contributing to the build.


The tug is 26 feet long with a beam of about 7 feet, a draft of four feet and displacing around 4 tons.

Built as a cruising boat, the planking is aromatic port orford cedar from southern Oregon, over white oak frames. The cabin house sides are of mahogany. Power is supplied by a 39 hp Yanmar diesel engine.




 Not surprisingly the tug was quickly sold to an owner, who based in Michigan will use her to enjoy the fresh water of Traverse Bay.

Jay Benford Cruising Dory Badger

In 1978, Jay Benford expanded on his cruising experience in the 34 foot topsail ketch, Sunrise, to create a dory hulled cruising boat. There were naysayers then, as now, about the capacity of a sailing dory to weather off-shore conditions.


 Annie and Pete Hill made the Badger famous and proved Mr Benfords design by sailing their dory over 100,000 nautical miles. Since then, we find Benford Badgers being built everywhere. It is a cruising yacht designed for the home builder.


Annie, of course, loved her plywood dory and had this to say in her book Voyaging on a Small Income:
"Badger can be built simply and for very little money. Sheathed in cloth and epoxy, she is easy to maintain and can be kept up to standard at very little expense - an essential prerequisite for a boat that is sailed on a small income." 
The Badger was originally designed with a cutter sail rig, but most builders prefer a fully battened schooner junk configuration, which has been touted as possibly the best short-handed cruising rig ever devised.


In Ullapool, Scotland we find a recently launched Badger setting out for its first cruise. Dan Johnson is the happy builder of Hester. He and his wife Charlotte Watters have spent several years exploring northern Atlantic venues, so for their first cruise on Hester, will be heading south.


Dan, with occasional help from friends, built Hester in two years. An impressive schedule for readying an open-ocean cruiser and a testament to Annies claim about simplicity of build, also to the commitment of the builder.


Dan and Charlotte have been impressed with the boats handling, as documented in Dans log:

"...we had made it down to Oban where we left Hestur for a week. After that, Charlotte and I returned to sail north again back to Ullapool. Of course we were hit by five days of northeast winds (absolutely our direction of travel) This would really show us how Junks go to windward - they do."

"Heading north we decided to go inside Mull then outside Skye taking in the Outer Hebridies. This proved to be a good plan as the Minch provides a great seaway for tacking against northerly winds! Heading west across the Minch towards Barra we experienced our first largish sea and strongish wind aboard Hestur - F6 with 10 foot crashers. She performed perfectly with nothing unexpected and we were broad reaching at 6+ knots with two panels up on the foresail and three in the main. Very easy sailing with no deck work - all reefing done from cockpit"

"When sailing on the wind she will sail herself if you balance the sails - we often leave the helm quite literally for hours and hours, not even lashed. This surprises me as she is a fin keeler - I think it must be the substantial skeg arrangement."

Being a dory sailor myself, I find this account impressive and would like to offer congratulations to Dan and Charlotte. May they find many happy miles at sea!

Thank you, John McIntyre and Chris Perkins of Ullapool for the photos of Hester.

Cape Henry 21 Trailer Sailer Cruising

Richard Hunter lives in Czech Republic and bought himself a Cape Henry 21 that was built in UK by amateur builder Gary Wallis. He sails it mostly on Berzdorfer See in Germany. He recently towed it 1200km to Croatia with a 1.9 litre VW Transporter to cruise in the waters of Croatia. With his wife and three teenagers on the trip, they used the van and boat as overnight accommodation en-route.

Once in the water, they set off with everything needed by the 5 people and cruised for a week, without having to put into harbour to stock up. Their little cruiser took it all very well, allowing them to anchor close to shore in private spots that are inaccessible to the much bigger charter boats. Their boat is quick in the conditions normal to that area in summer, even with the big load that she was carrying. They found themselves enjoying great sailing while the big charter boats went by, motoring port-to-port.

Stowage nets for stores for 5 people.
 Richard sent me a video and photos recording their holiday, as well as some nice writing about the experience. He sums it all up in a few sentences.
