NAVIGATION AIDS FOR HIGH-SPEED CRAFT - PART 2.

In the first part of this article, some of the latest developments in navaids appropriate to smaller craft were described. These included simple speed measuring devices - anemometers and water logs, compasses, foghorns and radar deflectors and night vision systems. Although progress in electronic development was readily apparent when reviewing these areas, such progress is dwarfed when the more advanced systems appropriate to larger craft are considered. These systems are reviewed in this article.
