How critical is a gps?

fishshim,

I like the way you think

I have the Eagle Cuda 250 with the GPS. Works great, but I also carry a handheld GPS in my PFD pocket. And a VHF radio in my other pocket. And a compass strapped to the deck. I probably use the compass the most. In heavy fog, you can't beat a GPS, though.

I like to have the GPS and VHF in my PFD because that may be all I have if I get knocked overboard or my FF battery fails. I'm much more worried about a wine-gulping yoyo running me over with his yacht than a GWS attack. This nearly happened to me in Monterey Bay last year. A sailboat just missed me, despite my attempts to signal them. As it passed, I noticed that everybody on board was looking behind them. That's why I don't go out on Wednesday afternoons any more. Too many sailboats with unskilled captains.

Or maybe you could take the $100 you'll save by going with a discreet sonar, and put it into a deck mounted compass and some other safety gear.

I've used one of these on my kayaks for several years. The great part is that you only need to drill two small holes in each boat for the screws that are permanent mounts for the portable compass. They run about $50-$55.
