from the pilothouse

Maritime Northwest Washington is dubbed “The Evergreen State,” which is a half-truth. The geological demarcation line between the two sides is the Cascade Range—a lineup of peaks that includes Washington’s highest (14,411 foot Mt. Rainier), and the most recent to blow its lid (Mount Saint Helens in 1980). Eastern Washington is beautiful but different. It features rolling hills, lakes, farmlands, and is home to Yakima, a world-class producer of wine as well as a large percentage of the world’s hops. West of the Cascades, another, smaller mountain range overlooks the Pacific. The Olympics and Cascades combine to dwarf 100-milelong Puget Sound, the second largest estuary in the United States after Chesapeake Bay. The sound is a protected waterway—protected rom ocean swells, anyway—and is strewn with islands, rocky beaches, and plenty of seafaring…

q&a with sterling hines-elzinga

Many of us use divers to maintain what lies beneath or only deal with these areas when hauled out. We turned to our good friend Sterling Hines-Elzinga, owner of Sterling Marine Services, a dive service in Seattle, Washington, to discuss what he thinks owners should know. How did Sterling Marine get its start? As a long-time boater, when I got my start as a marine professional I saw a need for a new, reliable, professional underwater service company. Sterling Marine started with just me diving boats and providing simple yacht services. Since then, Sterling Marine has grown into a leading underwater service provider and commercial dive company in the greater Seattle area. What role do your divers play for their clients? Our divers connect the yacht owner with the unreachable parts of their vessel.…

remembering bob smith

The last time I saw Bob Smith was at the Annapolis Boat Show, just a few short years ago. He was perched on a stool in his American Diesel booth, behind a table that was decorated with Ford Lehman diesel engine parts—pistons, valves, water pumps, exhaust elbows—that had failed due to corrosion, poor maintenance, or abuse. Bob saw me coming, looked me in the eye, and with a straight face said, “Well, it looks like they’ll let anybody in here.” Then he’d smile, stand up, and come forward with an extended hand and a solid grip that said, “Welcome, friend.” Robert Frederick Smith, or “Diesel Bob” as some called him, made the journey to Fiddler’s Green in January of this year, leaving behind a legion of boat owners who, whether they…

FURTHER DISSECTION Thank you for your excellent article and analysis. Under the Pennsylvania Rule, 86 U.S. 125 (1874), Nap Tyme’s clear violation of Rule 5 could mean that Nap Tyme was the cause of the collision. This is a rebuttable presumption—not impossible to rebut, but perhaps very difficult. Also, it is entirely possible that the ferry was a vessel restricted in her ability to maneuver because of the nature of her work. The examples in Rule 3(g) are just that—examples. Consequently, under Rule 18(a), perhaps Nap Tyme was obligated to “keep out of the way of ” the ferry. Finally, Rule 15 contains some curious language: “… if the circumstances of the case admit ….” I could find no discussion of this language in Farwell’s Rules of the Nautical Road (8th ed., 2005). I guess…

maintaining engine temperatures

Diesel engines generate high internal temperatures and this heat wreaks havoc with the various systems. In addition to keeping the engine from overheating, the cooling system on a modern diesel must also maintain the temperature of the lubrication oil, transmission oil, air intake, and fuel. This process takes place through a series of heat exchangers, as many as five on some engines. Heat exchangers operate in a harsh environment and failures occur regularly. By understanding how these components function and how to monitor their condition, you can greatly reduce the risk of failure on your boat. Regardless of the application, each cooler or heat exchanger works in the same way: one liquid circulates inside a closed set of tubes while another liquid flows around the outside of those tubes. The liquid…

sonic vibration: what’s the frequency, kenneth?

Keeping growth off our boats is a constant, unsatisfying battle. Growth rates of barnacles, mussels, and plant life change with water temperatures and seasons, bottom paint recipes change with environmental regulation, and the frequency at which we use our boats all impact how quickly ugly beards grow below the waterline. We employ a variety of methods to deal with growth, from having divers clean the hull, to costly haul-outs to remove growth and apply new bottom paint. In this never ending battle there is a tool that is often under-utilized: ultrasonic antifouling systems. Ultrasonic antifouling is not a new concept. The United States Navy first discovered it in the 1950s during sonar testing with submarines. It was found that hull growth was far less substantial around the sonar tubes than on…
