I've done some trips to the Channel Islands on beachcats and more recently on monohulls from a sailing co-op yacht club I joined a couple years ago. So my navigation needs may be more demanding than yours, but anyway....
I've been using a Garmin GPSMap 76Cx, without the added charts. You get rough polygons to represent land masses, but you can establish way points and routes on your computer using free software from Garmin, then can transfer recorded tracks back to the computer for review.
The interface plug started getting flakey on me, not allowing me to get the tracks, and also requiring entering the way points by hand on the device which is a real pain in the a**. But then I found I could get it to work partially inserted with some side force applied.
I was preparing for a 6 day trip to the islands on one of the club Catalina 30s, and found the chart plotter to have the same landmass polygons as on the Garmin. I tried getting the Garmin Blue marine charts, but they are no longer available for the 76Cx.
So I picked up a Garmin GPSMap 78sc which has the charts built in. It has more features than the 76Cx and you can even configure menu choices and which data elements you want displayed on the some of the screen. I picked it up on sale at West Marine for $200, the regular price being $280. I keep it in a drybag as I just don't trust IPX ratings. (The battery compartment on the 76Cx leaked. I didn't have the stamina to fight with West Marine like I did in the old days getting all their radios redesigned, but that's another story).
I've been really happy with this device. The only drawback is that it chews up batteries, draining alkalines after only about a day and a half of use. I've switched to lithium and getting way more life, but they are pricey. There are some tips online on how to extend battery life which I need to look into.
Here's a link to the product:

Sorry for rambling. It's what I do.
