Marco Island Power Squadron students learn the use of sextants to locate position. The Junior Navigation course deals with learning the basics of celestial positioning. Students must do a run on the upper and lower limbs of the sun. A single sight fromeach of these two runs is then reduced and the resulting lines of position are plotted as a running fix. Students must be accurate to within five miles.
The Squadron offers Safe Boating classes to the public at no charge as a public service and offers many boating-related courses to its members from Seamanship to Celestial Navigation. The Marco Squadron has over 175 members and is part of the United States Power Squadron.
