    GPS vs Celestial... new consideration

    Apparently there is now the possibility that GPS could be taken out not locally, but ocean-wide: https://arstechnica.com/space/2026/06/tests-suggest-russian-satellites-can-jam-gps-on-a-continental-scale/ Offshore I always carry a (plastic) sextant and the appropriate manuals, but... I don't...

  2. Is Orca the New Apex Predator of Marine Navigation?

    E32-3 Is Orca the New Apex Predator of Marine Navigation?

    Preface I'm currently testing Orca Navigation on my boat. My tests are interrupted by the work on Rumour's bottom and keel, so I thought I would place a summary of what I've found so far in the forums. I started writing a few pros and cons, which then led to feature analysis. The more I learned...

    Paper Navigation Charts. 20 pounds worth.

    Not sure what to do with 20 Pounds of Paper Navigation Charts.:confused: My Father has been collecting Navigation Charts since the mid 1960's through the mid 1990's. Dad did some extensive cruising in the Pacific Northwest, British Columbia & Alaska, so there are quite a few of those areas...

    Fugawi to Raymarine

    Has anyone attempted to transfer waypoints and routes from Fugawi PC S/W to Raymarine C Series Chartplotter and been successful? I can't seem to make it happen even using GPSBabel to translate.

    Online navigation course

    Anyone have any experience with this online navigation course? http://www.boatsafe.com/navigation/index.htm I would like to get some basic instruction in coastal navigation and $70 seems like a fair price. (Other suggestions also welcome.)

    64 Bit Vista and Navigation Software

    So I have never had anything nice to say about Vista and now I am finding out that Maptech Offshore Navigator software will not install with 64 bit vista. Can any of you tech gurus comment on this? I just bought a new laptop with 64 bit vista installed and was really hoping to use it on the...

    Navigation Lights - Mast Light Placement

    I'm going up to do some work on our "new" E29 in about a month. The PO said that the lights on the mast did not work so we will be re-wiring the mast and replacing light fixtures. I know that we need a Steaming light for use under power. I keep seeing a reference to spreader lights. Could...

    Onboard Navigation with Macintosh vs. PC

    I am contemplating a laptop purchase pretty soon. It will be both a desktop replacement and a cruising portable. I am thinking about a Mac laptop, in addition to the more familiar (to me) Dell or other manufacturer PC platform. In addition to marine navigation of course we'll need to do wireless...

    GPS and traditional navigation

    hello All, I put this topic here as it didn't seem to fit elsewhere..... My wife and I are currently "discussing" the relative merits of GPS vs traditional navigation. This occurs as our chartplotter is not working correctly and I would simply like to replace it or remove it. I don't trust...

    Merrimac River Inlet Navigation Pointers

    I was doing some surfing on the web and found 2 references to the Merrimac River inlet in MA being the 2nd most dangerous inlet in the US. I know the area can be difficult to negotiate at times but does anyone have any pointers for sailboats for this inlet? The only things I have read are...

    Computer Navigation Software

    I saw Gareth mention that he switched over to a laptop, so I was curious as to what others are using/have used for Nav. software. I plan on getting Nobeltec for the upcoming season, but I am open to ideas.
