om... "Jeff Morris" wrote in message ... How about: Depth Sounder Bottom from lead line Bottom mavigation is indeed another way to navigate. One of my favorites since it serves as a reality check on other methods. Sound from fog horns & bell/gong buoys. Good one but very restrictive! Fortunately I don't have to use this much anymore! .... Also, "DR" doesn't include Piloting, or using local geographic features. I dissagree. To trianglate off distance features is DR'n IMHO. Nah. In any definition I've heard of Dead Reckoning is that it specifically does not include piloting techniques that would yield a "fix." DR is what you do between fixes. For reference, see: http://pollux.nss.nima.mil/pubs/pubs...s.html?rid=187 Chapter 1 begins with a brief discussion of the difference between various types of navigation; Chapters 7 and 8 discuss DR and Piloting respectively. -jeff |

Lifelines Part II
Nutsy (BB)
If you can post the AA site, it shouldn't be a problem to post the manufactures site showing a 20hp diesel using 1 gal/hr A Troll is a Troll even if it under the name of a puppet. Right Nutsy? Even a drunk knows that. It is only the stupid and weak minded that think otherwise AND: "I'LL DRINK TO THAT!!" Ole Thom |

Lifelines Part II
He's full of **** Alan, but it would be interesting to catch him in a
blatant lie. "Alan Gomes" wrote in message news:Iuo_b.380216$xy6.2073718@attbi_s02... So you are saying that lifelines are required equipment for Cal 20 class racing on the East Coast? I just want to confirm what the claim is before I check it out. --AG "JAXAshby" wrote in message ... they are required on this end of the world. with about 5 or 6 C20s in various stages of renovation--no lifelines on those, either. |

no, "celestial" as the term is used means to use an accurate timepiece. Lunar distances needs no timepiece at all, let alone an accurate one. Sorry, Jax... wrong again. You should be proud of your perfect record. "Celestial" navigation means to use "celestial" bodies. And the lunar distance is a method of telling time, making the "celestial" bodies themselves a timepiece. So you are doubly wrong. Your mom would be so proud! Fresh Breezes- Doug King |

Joe Fresh Breezes- Doug King I would consider piloting a separate method, but for me it would involve use of visual bearings, soundings, radar range and bearings, special cases. This does not fall under "DR". Did someone mention DECCA, and is it still in use? otn |

Most would consider Lunar distances as celestial, since the moon is a celistial body ya know. Same with a sun line, star fix ect. Joe Sorry Jax, but "celestial" is "of the heavens; of the sky" by observing the sun, moon, planets, stars. Lunar distances fall into this category, and a timepiece is NOT the major sticking point. Celestial navigation was around long before an accurate sea going timepiece was invented. otn |

Omega has been gone a while, I think the only Decca chain is still active in the North Sea oil fields but is closing up shop in the near future. DSK |
