How do you navigate

Do you rely on .
Trad Nav
A mixture of both
Or I know my area like the back of my hand so don't bother.

In my opinion paper charts are as much use as a chocolate tea pot on an open RIB.

I use a Garmin 178C chartplotter and I have a Garmin Foretrex 100 wrist mounted GPS as backup. So if im venturing out of an area that I know like the back of my hand at least I have a completely separate backup way of finding a safe haven should my main chartplotter fail.

This of course will not help if the GPS system its self (ie the satellites) goes down (im not sure how likely this is to ever happen) but if it ever sould i still have a console mounted Plastimo 75 compass and also a Plastimo Iris 50 handbearing compass so that I at least know which direction I'm travelling - but this obviously is reliant on you having a good knowledge of where you were when the GPS went down.

Except for trad nav:- all of the above. Ribs are not the best place to do EP's or DR. Though I do mark last confirmed position/next route using chinagraph pencil on the chart cover.
I tend to use the GPS to get me started, then read off a mag bearing and follow the compass for passages, rather than just the plotter.
At night though I tend to follow the plotter as my compass is a bit difficult to read at night.

1. Eyes.
2. Local knowledge.
3. Chart plotter.
4. Memory. (with route plan and chart handy by).
5. Hand held GPS.
6. Fixed Compass.
7. Hand bearing compass.
8. Water resistant charts & portland plotter. (No dividers on the tubes)

In roughly that order. As one fails, I move down the list.

Local Knowlege, and if its somewhere new I usually have a quick look through the Almanac or Sailing/Cruising directions to get an idea of any dangers/marks and then use the plotter/charts.
I will usually have charts for the area handy, as sods law dictates the plotter will have a "funny turn" just when you need it the most.

whilst i know the Solent quite well

1) Charts + Plan (written down in big letter/numbers). Both in the plastic thing you would get with the small charts. On the Scorpion there is a small gap between the console and the screen, so i shove it down there
2) Chartplotter to check, while i'm zipping along
3) Handheld GSP, with spare batteries if chartplotter fails.

4) Chartplotter + sextant when i went across the pond
