How many of you rely on your GPS without consulting charts these days? How many of you back that up by using a handheld compass? No judgements, and I'm sure some will get on a high horse after lying about it. Just curious. My GPS is a very early handheld mapping unit (GPSMap 175) which provides limited charting info, assuming I have the chart chip. I always have a paper chart on deck and consider that my primary tool. I'm thinking about getting the new small Garmin that has NEXRAD updates and can also be used in a car, but the screen is still pretty small so I doubt it will replace paper charts. BTW, my boat is wired for computer charting, and I have software and charts, but I never felt comfortable relying on it. A close friend, who is a traditionalist in many other ways, has his autopilot driven by the computer. I hardly ever use a handbearing compass nowadays, but I used to use it a lot before GPS. I do use soundings frequently to double check positions. Also, when I travel outside of home waters, I often have dividers and sometimes parallel rules on deck. As for Notice to Mariners, I subscribe to the local edition and read it weekly, though I don't update charts. |

I just print the sections that apply to where I'm going, then I update the paper chart in pencil the night before. When something changes, I make the change or erase the notation as necessary. -- "j" ganz @@ www.sailnow.com |

Jeff, have a look at the new Garmin GPS 192c. It comes fully loaded with all US Charts. I ordered one for the 35s5. It's quite a good value and has a great screen. RB |

Then I use a PC to plot courses which I load into my cockpit GPS, which then provides a continuous display of current position relative to plan, hazards, depth, et al and automatically scrolls. Makes "driving" the boat a snap. The boat has a compass that I steer by (tacks may criss-cross the planned course shown on the GPS). I keep a laptop connected to a separate GPS in the cabin for backup and a bigger picture than the GPS screen provides plus charts on the Nav desk to note interesting data for future use, but I do not maintain current track on charts. My health limits us to day sails, and not even that lately - were we taking longer trips I'd update the charts every few hours just for drill. I've checked GPS position against charted position of bouys, et cetera, and found it always within a few yards - mucho better than I can do using a compass to triangulate position but y'all good sailors prolly have better results than I. |
