Marine Navigation

Marine Navigation is the first course in the sequence of USPS courses on navigation, covering the basics of coastal and inland navigation. This course focuses on navigation as it is done on recreational boats today and embraces GPS as a primary navigation tool while covering enough of traditional techniques so the student will be able to find his/her way even if their GPS fails. 

• Charts and their interpretation
• Navigation aids and how they point to safe water
• Plotting courses and determining direction and distance
• The mariner’s compass and converting between True and Magnetic
• Use of GPS – typical GPS displays and information they provide, setting up waypoints and routes, staying on a GPS route.
• Pre-planning safe courses and entering them into the GPS
• Monitoring progress and determining position by both GPS and traditional techniques such as bearings and dead reckoning
• The “Seaman’s Eye” – simple skills for checking that one is on course.

The first in a two-part program of study in offshore navigation, followed by the Celestial Navigation course (currently offered as Navigation.). It is designed as a practical "how to" course. Subject matter includes:

• Precise time determination
• Use of the Nautical Almanac
• Taking sextant sights of the sun
• Reducing sights to establish lines of position
• Special charts and plotting sheets for offshore navigation
• Offshore navigational routines for recreational craft
• Electronic and computerized offshore navigation
