M_Boats: Navigation GPS

Ahoy Skippers This weekend we rounded the W. end of Catalina (on my cousins Catalina 310) at midnight a sailed into Catalina harbor. My old GPS gave me fixes which I plotted onto a chart to see our track and make sure we were not going aground. There was no visibility and I found myself hallucinating in the night and spending way too much time plotting our track. I decided if we make it through this and I could get back to the form I would ask you skippers if you are using GPS systems with plotting capabilities? What are the hot systems?
