Deduced Reckoning relies upon having a good position (that is a good fix) – to calculate your current position at a later date without the use of GPS.
During courses we find attendees admitting they lost their electrics at one stage or another – as you’d expect, it is usually at night in big seas! But whatever the weather you need to always know where you are and if you keep your logbook up to date hourly with a quick note of your latitude and longitude, should the GPS fail then you can extend your course and distance on your chart from your latest fix and know where you are and what your next action should be.
You can also use these techniques to find set and drift.
This includes full support, you can call/email us for help if you need it.
The individual module costs are refundable if you complete any of the modules (up to 9) and then decide to purchase the complete Navigation course (enroll for $99).
