I've still got a Garmin 200 Plotter ('80's) that works, with chips, from pre Combo days. also an old Calculator with Nav Tables in it. Pre the Sat Nav/GPS days.
For coastal, one of the most useful tools with Bino's and compass, is the old H/Held RDF.
They pick up radio towers/Stations and ALL coastal Airport Control towers that are on your charts.
Just add deflection and they great for paper Navigation.(Triangulation)
If using a sextant. try the Aero Nav charts. Not as accurate as true charts but easier to compute. And set the elevation of star? in. B4 you scan for it.
Makes it a lot easier.
I've still got my Walker 3 Towing Log and Plath Sextant from sailing days.
The Sextant I was given from my old skipper 50 odd yrs ago. Still true.
and log would be 40 if a day too.
One day I'll pass them on to somebody interested/worthy.
Everybody who goes out of sight should have and know how to read a sextant..
You lose electrics. 90% of them wouldn't know how to read sea sets or know North
with or without a watch.
Once you away from coast and backwash waves. the "groundswell" is a constant bearing mainly. Winds only stir up the surface waves.
Take note of that and it'll help you hold a course.
there's too much complacancy nowadays. Even ship Navigators have to show competence with Sextant.
and all our Aust Navy Patrol boats have Garmin GPS in Nav Stations.With the charts.
People should try practicing at times. It can be fun. and very mentally stimulating.
