Which boat is most likely to capsize ?

The AVS for all these boat sucks. The Catalina and Tayana can barely go below horizontal! Not good or not right! Tayana claims a much better AVS than this. Gaz Check out: http://www.image-ination.com/sailcalc.html Calculate this stuff yourself. Thanks Gary. The AVS value of 110 degrees for Tayana Vancouver 460 was given to me by Tayana along with the report shown on my web page at http://tayana46.tripod.com/safety.htm. Looking at the curve at the bottom of this web page wouldn't you say that this is the correct value ? The AVS numbers for the Beneteau 473 and Catalina 42 mark II were taken from: http://www.rya.org.uk/images/uploade...e_10_11_05.pdf |

( I worked on a new 46 two years ago) As far as capsizing: Unless you plan to start sailing soon, and then take many lessons, practice on countless trips for a few years and learn to master each and every one of the mechanical systems aboard before rounding one of the Capes, you'll face far worse and more probable problems than capsizing. And, as your best friend, I would gladly pay you on Tuesday for the George Forman grill upgrade today on this baby. Burgers and beers in the tropics! Yum! Fair Winds and calm sea, Whimpie Thanks Whimpie The boat is almost done and I've already seen several pictures taken at the factory. Both the dealer and the Tayana engineer I talked to told me that it's just going to take about 2 more months. I can ask the dealer if the rigging cost is included in the selling price. I don't plan on crossing any ocean until 2007 or later :-) |

Which boat is most likely to capsize ?
Does it matter? Are you actually planning on sailing out of the bay or
river you live on? Most yacht owners day sail or spend a week in sheltered bays and never put to sea. My guess is you will be doing the same. All that is left is Rhetoric.

Apparently you haven't been following. This guy has bought Thailand and is
in no hurry to get there. "d parker" wrote in message ... Does it matter? Are you actually planning on sailing out of the bay or river you live on?

Which boat is most likely to capsize ?
Danny,
Unfortunatly I am periously close to Poopie (love the spelling.) Last year I bought a bunch of land in Nova Scotia, a 20 year old 33' custom steel cutter, and moved one to the other. Never sailed before but lots of time on stink pots. Anyway I got there, after about a week. A little over 400 miles, on the chart. I think you are right that he is trolling for amusement. But it IS amusing. Not only his posts but the dead serious answers intermixed with the others who have "outed" him. And, you gotta admit, he must have the hide of a rhino. Or is it brain. Either way, for now he does make me laugh, if only at myself. Howard |

The Angle of vanishing stability,Ballast/displacement and
the Capsize screening ratio are useful in choosing a sailboat. However, I would not take all these calculated ratio's for granted. How can you validate these ratio's. The best thing is to corroborate the designs in real situation. This is very difficult to accomplish. How can you duplicate a real situation. Computer simulations can be helpful to validate your design to a certain extent but never at 100%. Sea trials, track records and past performance in all imaginable conditions can be very useful to corroborate computer simulations and to confirm applicable ratio's. wrote in message . net... wrote: TAYANA VANCOUVER 460 PILOT Angle of vanishing stability = 110 degrees Ballast/displacement = 0.24 Capsize screening ratio = 1.57 BENETEAU 473 Angle of vanishing stability = 119 degrees Ballast/displacement = 0.34 Capsize screening ratio = 1.96 CATALINA 42 MARK II Angle of vanishing stability = 105 degrees Ballast/displacement = 0.39 Capsize screening ratio = 1.97 ETAP 46DS (standard deep keel) Angle of vanishing stability = 129 degrees Ballast/displacement ratio = 0.32 Capsize screening ratio = 1.92 Maybe I'll just get a Tayana for now and get an unsinkable ETAP later when I have more money and want to sail across an ocean :-) |

How's the sailing in NS in the winter? My brother in-law lives in Portland, Maine. The combination of the ridiculous fog and the rocky shore make the case for your steel hull. Danny |
