dougies and jeffies and others seem eternally worried about NAVIGATING AT SEA
without triple redundant gps's, RDF, working C. Plath sextant, Almanac, chronometer and SSB for time clicks. This sailor -- who has sailed something more than a Hunter 19 or training wheels -- thinks a single cardboard beer box is enough. "When we asked what Babe would use to navigate, he pulled out a crude astrolabe-like device he made from the cardboard from a beer box. "With this, I can get my position, without tables or a watch, to within 60 miles." see link for more of the story: http://www.latitude38.com/LectronicL...#anchor1085433 |

Hey jaxie, you're the one who had three GPS's and Loran and was still afraid of
hitting the "rocks" at Cape Hatteras. You even showed a picture of the surf ten miles away from the light to show how dangerous it was. Your first comment on the experience was that it would be impossible without a GPS! I used to cruise the Maine coast, often going 30 miles off shore and making landfall in the fog with nothing more than a Ray-Jefferson RDF. I also carried a paper "lifeboat sextant" but had little occasion to use it. You, on the other hand, are scared ****less of being within 10 miles of shoals, even with 3 GPS's on board! If you just learned how to read a chart and use a compass the world wouldn't be such a scary place, jaxie!

jeffies, if you "navigated" through fog off Maine using just an RDF, either you
didn't understand just how lucky you were, or you were purposely trying to kill yourself. RDF gets you "kinda close" but that's about it. It is good for know approximately where you are. So, did you understand the danger you put yourself in or didn't you? btw jeffies, why your claim now that you are willing to blunder around blindly in a fog along a rocky coast where in the past you claimed EVERYone needed a sextant as a backup in case "all the electronics went bad" btw-2, we did indeed have a gps etc but we knew enough not to trust the charts as close as we were going. If we didn't find the light where we expected to find it, we would turn around. We found it. you, on the over hand, claim you just blundered on. you were lucky, dumbass. and, it appears, to this day you don't know it.

RDF gets you "kinda close" but that's about it. It is good for know approximately where you are. You really do need to get some training, Jax. RDF was frequently used as an approach system to obtain some reasonably accurate positions, which could be augmented by other methods, or augment those other methods to get some very accurate positions, especially when used by an experienced operator with a calibrated receiver. So, did you understand the danger you put yourself in or didn't you? btw jeffies, why your claim now that you are willing to blunder around blindly in a fog along a rocky coast where in the past you claimed EVERYone needed a sextant as a backup in case "all the electronics went bad" G You still haven't learned that a sextant is normally used for offshore navigation. btw-2, we did indeed have a gps etc but we knew enough not to trust the charts as close as we were going. If we didn't find the light where we expected to find it, we would turn around. We found it. you, on the over hand, claim you just blundered on. If you didn't trust the charts, why?, and why were you running that close if this was the case? Sounds like some bad decision making when doing your route planning. otn |

Well, I also had a compass, depth sounder, charts, and the knowledge of how to
use them. RDF is certainly less than perfect, but its a lot better than you claim. It was considered to be accurate to 2 degrees, but I generally assumed I'd get no better the 5 degrees with my small unit. However, when you're running down the coast wondering if you've passed Portland or Monhegan the RDF is very handy. There were a large number of radio beacons back then, so they were quite useful for navigation. A number of them had radio signals synchronized to fog signals, so it was possible to determine distance off. Jaxie, millions of people sailed before the GPS was invented. Just because you're scared ****less to go anywhere without three of them doesn't mean everyone else is. Your story (lets be honest, its a "fantasy," right?) doesn't hold water. The light at Diamond Shoals is miles away from the shoals and visible for 18 miles. If you had any experience in using a gps or even your depth sounder, you would have had no trouble finding it. Getting "within 20 seconds of turning back" is NOT something that happens to an experienced mariner in this situation. As for the sextant, I never, ever made the claims that you say. In fact, I've probably said its not worth learning how to use one unless you really want to. I do think that the rudiments of celestial should be learned by anyone who goes offshore, but it isn't necessary. Sextants are fun to use, and handy for some types of piloting, but I haven't carried a quality sextant on board in many years.

over the nee, you obviously have no idea how RDF works.
[snip a bunch of nonsense, but leave the following nonsense in] If you didn't trust the charts, why?, oh, I dunno. good seamanship maybe? An understanding of how charts were produced? Maybe just making sure the lights were working that night? and why were you running that close if this was the case? because we could see the lights, and they appeared where we expected them too. When one didn't appear as expected we became extremely watchful, and were ready to turn around if it didn't appear very shortly. It appeared. Sounds like some bad decision making when doing your route planning. I didn't plan the route. The career merchant marine with a couple decades offshore racing experience did. He was trying to skirt inside the Gulf Stream so we didn't have to cross it and then recross it sometime later. If the light hadn't appeared we were within a few seconds of turning around. so, what's the problem? |

jeffie, no RDF on any sailboat gave "accuracy" to withing 5*, let alone 2*.
Your statement just shows you have no idea how RDF works. wondering if you've passed Portland or Monhegan the RDF is very handy. that is "5 degrees" by your estimation above? yeah, un huh. millions of people sailed before the GPS was invented. No kidding? wanna take a guess how many of those who wandered around in a fog with granite ledges in the water made port? For your information, approximated 25% of ALL commercial shipping vessels made in the last 50 years of sail powered shipping sunk before the boats were retired. one in four. That is what fog and granite is for, to sink ships. ask around with the old timers and see what they did say 40 years ago. btw, well into the 1970's and even into the 1980's a cheap tranistor radio from Radio Schack was considered an acceptable alternative to the commercially available RDF units for recreational sailboats. Why a cheap radio from Radio Schack? Because the cheap radio had a more directional antenna than the better quality radios. I believe Hal Roth used a Radio Schack radio into the 1970's and carried it as back up even later. Getting "within 20 seconds of turning back" is NOT something that happens to an experienced mariner in this situation. really? you mean that career merchant marine was inexperienced? I kinda think of him as a bit more seaman than some clown plowing through the granite ledges of Maine listening to rock music radio stations (and a couple of dit dah dah dit dah stations) to determine where he was. btw, that paper sextant you said you carried and used in the fog to tell where you were, didn't the moisture in the fog cause the paper to fall apart? |

sail powered commercial shipping was kaput long before any u-boats got on this
side of the atlantic. For your information, approximated 25% of ALL commercial shipping vessels made in the last 50 years of sail powered shipping sunk before the boats were retired. one in four. it was those darn U-boats hiding in LIS. SV |

[snip a bunch of nonsense, but leave the following nonsense in] ROFLMAO In other words, Jax, YOU don't know anything about RDF as used on ships, and didn't, as per usual have a clue as to how it could be used, or what I was talking about. If you didn't trust the charts, why?, oh, I dunno. \ You got THAT right !!!! snipped a bunch of nonsense and why were you running that close if this was the case? because we could see the lights, and they appeared where we expected them too. When one didn't appear as expected we became extremely watchful, and were ready to turn around if it didn't appear very shortly. It appeared. In other words, you could not trust your navigation skills ..... wise choice. It's becoming more and more obvious that the only thing you are experienced at is walking the floors and docks at boat shows, reading boating magazines, and occasionally sailing as someone's crew. Sounds like some bad decision making when doing your route planning. I didn't plan the route. The career merchant marine with a couple decades offshore racing experience did. He was trying to skirt inside the Gulf Stream so we didn't have to cross it and then recross it sometime later. If the light hadn't appeared we were within a few seconds of turning around. so, what's the problem? Career merchant marine...... sure .... none of us believe that one. Jax, the more of your post I read on this subject, the more I know you don't have any experience or knowledge of the subject at hand. You were along for the ride, and don't know what was going on or why. otn |
