I get around the Hawaiian islands just fine with two hand-held GPS units (Garmin GPS-38s) and plenty of batteries. Out of sight of land, at night - no problem. Turn on the GPS, get a fix and plot your location on the chart every watch change (every four hours)then turn the unit off to save batteries. Enter your location, time, speed and course in the log.
Of course prudence is always a virtue; the prime quality of a good navigator. Double check every plot. I never approach land at night, GPS or not, except home port which is well known to me and very well marked with lights.
You will also need a depth sounder, knot meter and appropriate paper charts, plotting tools, pencils etc. I find a hand bearing compass very usefull when land or other vessels are in sight. It is indispensable for coastal navigation. I like the pistol grip type for a positive fix. A good pair of binoculars will also come in handy. Of course, you will need to know how to use the stuff and how to accurately plot your location on a paper chart. Practice at home before you go to sea.
