Taming the roll

Active stabilization won’t turn a rough sea ride into the feel of a flat calm, but these ingenious examples of marine engineering will make life aboard much more tolerable.

Diagnosing foul fuel

Clean fuel is a power cruising priority, and it’s important to pay heed to what goes into the tank(s) and what’s sloshing around in the sediment bowl of every filter. But more often than not it’s what lies between the fuel fill and the primary filter that hides the problem.

A gathering of the pros

To the editor: Weather forecasting is both an art and a science, and sailors and power cruisers have become major consumers of a wide array of this crucial information. The three big weather questions we face are: 1) how much…

Power seafaring defined

Half Niagara Falls barrel, half high-performance motor boat, the U.S. Coast Guard’s 47-foot motor lifeboat is anything but your average power cruiser.

Learning the ropes

High-strength materials way beyond nylon and Dacron are changing the capabilities of voyaging lines

Radar revisited

Even with all the advances in marine electronics, radar remains a must-have tool for the voyager

A coatings challenge

Iron-based keels provide superior strength, but need careful protection from corrosion with epoxy coatings
