Silence on the hook

by Nigel Calder, Posted August 3, 2009
As part of my hybrid-propulsion research I have been looking carefully at large-capacity Litihum-Ion batteries as a possible energy source on modern cruising sailboats. Lithium-ion batteries are common in cell phones and laptops, but they are rarely used in higher capacity applications. This may rapidly change, because the hybrid automotive and electric vehicle markets are in

Fuel and Water Don't Mix

by Sail Staff, Posted August 27, 2008
This wasn’t the first VHF call I had taken from someone seeking advice for an onboard problem, and the caller was clearly distraught. He had accidentally filled his diesel tank with fresh water. To make matters worse, when he tried to start the engine, fresh water had been sucked through the fuel system. Always interested in a challenge, I went over to his boat. Together we fixed the problem

Fresh air below

Despite all the progress in sailing gear and equipment certain aspects of life at sea never change. Keeping water out, maintaining good boatspeed, preserving and conserving food stores, and carrying adequate spares for the inevitable failures that occur are all perennial priorities. Plus one more thing; having a good supply of fresh air below.Someone once observed that

Spare-Parts Counter

Carry the spares that keep critical systems runningBy Don CaseyOur multi-year cruise was still mostly in front of us when our Yanmar diesel engine uncharacteristically refused to answer my call for more revolutions. We reached our next port on reduced rpm, and the following morning the engine would start, but not keep running. When an otherwise mechanically sound

Honda Engines Ready for 2010 EPA Standards

by Sail Staff, Posted September 9, 2008
Honda Marine’s full line of current production models can meet the rigorous emissions standards set forth by a new EPA (Environmental Protection Agency) standard introduced Thursday, according to a company announcement."The EPA's new exhaust standards are based on those currently set forth by California Air Resources Board (CARB) 2008 marine regulations," said John Fulcher, senior manager,

Water power

by Nigel Calder, Posted August 17, 2009
My last two columns discussed the high cost of generating electricity with a diesel engine and the relatively short payback period for solar panels on liveaboard cruising boats. The problem with solar is that it requires a lot of surface area to produce significant amounts of power. This is relatively easy to find on catamarans, but not so on monohulls.Coincidentally, I received an email
My brother was hanging upside down, peering through a 9-inch square cutout in a bulkhead at the raw-water pump housing on his 3-cylinder Yanmar marine diesel. “How the heck do you get the impeller out of there?” he asked me.This is a very good question. Removing an impeller is something that should be done on a regular basis; Yanmar recommends replacing the impeller on this particular

Gravity Theory

Smell. Pong. Effluvium. Whichever way you describe it, the airborne essence emanating from Ostara’s aged sanitation system was highly unpleasant. More than just an odor but thankfully short of a full-blown stench, it permeated the forepeak and almost caused a spousal mutiny during our first weekend aboard. No doubt about it – something had to be done.The sanitation system comprised a
