- improving skill at navigation
- having fun doing the activities, and finding satisfaction in doing them well
- experiencing aesthetic appreciation of the concepts
- developing and improving versions of this curriculum that can be applied in future ed programs (both school and adult ed)
- developing a cadre of volunteer educators to implement any such ed programs

- Information contained on a chart: shoreline, depths, hazards, aids to navigation, landmarks, ranges
- Relation of flat chart to spherical Earth
- Geometric visualization meditations: intersections of lines and circles with other lines and circles, giving zero, one, or 2 points; angles
- Coordinates, points, lines of position (LOPs - including Lat & Lon), circles of position
- The bearing compass: getting the angle between a line of sight and Magnetic North
- Plotting your actual position on the chart: GPS coordinates; using any 2 LOPs from bearing compass and/or ranges
- Surveying as the reverse of navigation: 2 LOPs to plot a landmark

- Crude angle measurement with a protractor or pelorus
- COP from angle of elevation of top of object of known height
- Recipe to get a circle of position from the angle between 2 visible landmarks
- Plotting position from 2 COPs, or a COP and a LOP
- Geometry behind the "recipe" above; navigation as practical geometry - wealth of ed program material
- Better angle measurer than a protractor - a sextant!

- Anatomy and how it works (including avoiding damage)
- How to use it (horizontally and vertically); "pendulum-swinging"
- How to read results: index scale, micrometer drum, vernier; instrument errors
- Adjustments (e.g. mirrors) and calibrations (including parallax vs. index error)

- Basic tools: sextant, watch, almanac, Pub. 229 or equivalent; organized work sheet, plotting paper, plotting tools (straightedge, dividers, protractor)
- Geographical Position of a celestial object: changes with Earth's rotation; tabulated in Almanac; interpolation
- Zenith and horizon (ideal)
- Zenith distance of object, as seen from non-GP, and object's height above horizon
- Sextant measurement (noting exact time!) of object's height (ideal case: spherical Earth, no atmosphere, eye at sea level, object VERY far away)
- Ideal circle of position - plot on globe, with radius in angular form
- For fix, need 2nd COP from 2nd measurement

- Watch error (GP, center point of COP)
- Sextant index error
- Height of eye and dip correction; "artificial horizon"
- Refraction
- Parallax: correction for finite distance to celestial object

- Publication 229
- Assumed Position (AP), as determined by meshlike data in 229
- Plotting paper - "zoom" in on expected location of fix, close enough to make Earth flat, and arcs on COPs become LOPs
- LOP through AP, corrected via actual measured celestial height, to parallel LOP
- Repeat with new AP for 2nd celestial observation
- Triangle of position from 3 or more celestial observations
