Thinking Like Your GPS System

May 4, 2004

An article by Dick Aarons from Yachtingnet that discusses the problems that arise with having so many options to navigate your boat. It's a short guide into the different components of a ship's navigation system.

"Today's electronic navigation systems let you accomplish just about any navigation task in three or four ways. And therein lies the problem. Some of these systems offer so many options we can easily lose track of the fundamental task at hand: getting from point A to point B safely and relatively gracefully."

Tuning To A Quarter Wave

May 3, 2004

Nice thread on how short SSB antennas operate and why. The discussion is concerning antennas that are shorter than a quarter wavelength. It's a bit technical, but you might find it helpful if you are into SSB.

"It may seem like semantics but there are a lot of people that get confused and think that when making the system resonant with a shorter antenna that the antenna is really the same as a quarter wave length antenna when there is a loading coil. It is far from that. Its radiation resistance and its feed point resistance are both much lower."

Boat U.S.

May 3, 2004

Forbes awarded the Boat Owners Association of The United States (BoatU.S.) Web site as a �Best of the Web Pick. A special remark was made on Chuck Husick's marine electronics contributions.

"You can also find information on on-the-water towers, boat lettering services and boater education, and there's even a state-recognized free online boater safety course," she said. The Forbes.com editors rate each site according to five criteria: content, design, speed, navigation and customization, and BoatUS.com ranked near the top in every category, BoatU.S. said. "Some of the best information was the Boat Tech Guides with no-nonsense how-to's, and Chuck Husick's marine electronics information that demystifies higher-tech gear like GPS systems and electronic navigation charts," McErlane said."
