Not only does the HSF go a bit faster, it maneuvers in ways no "ship" could,
and stops in distances even much smaller yachts couldn't dream of..... Again....."apples and oranges"..... this class of boat/ship, needs to be thought of separately. otn "Steve Firth" wrote in message . .. otnmbrd wrote: Big difference between "high speed ferries" and ships. Hmm, well mostly that the HSF goes a bit faster. P&O used to have a 35 knot monohull ferry in the Irish Sea, now replaced with a wave piercing catamaran. The SS United States average 35.59 knots in 1952. Visby is a conventional RoRo with a design speed of 28.5 knots. There are also the eight fast cargo ships operated by the US Navy with a cruising speed of 30 knots. -- "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." -- Benjamin Franklin, 1759 |

SOME ferries have Voight Schneider, not most, and it's by NO means a high speed drive, although it will increase maneuverability. and stops in distances even much smaller yachts couldn't dream of..... As with the line above, hardly relevant. They float on water, they move around, some of them go fast. Wrong again. It's all VERY relevant, because what you can or cannot expect from any of the varying types is significantly different and what you don't know can get you run down. otn |

They're ships, and frankly they're the most frightening ships out there. And because they operate typically across busy straits, very often in order to get somewhere you _have_ to cross their track. -- (Simon Brooke) http://www.jasmine.org.uk/~simon/ ;; better than your average performing pineapple |

We have a ferry service running between here and Key West that uses large, high speed catamarans. They can run at 40 kts or so and are quite spectacular to watch at close range. I had an encounter with such a vessel last summer cruising from Croatia to Italy. I was 10nm from the Croatian coast on a NW course, singlehanded under sail when I noticed the vessel astern on my port quarter, at a guess circa 3 nm miles away - in the binoculars I could see the twin hulls; I judged it to be in an overtaking position to me. It was clearly traveling very fast and closing and the bearing did not appear to be changing; it was a classic collision course situation - the weather was clear and sunny, wind about 12knots, no other shipping visible. The ferry, for that is what it was, stood on and was getting very large, very quickly, and still coming straight for me, although I was beginning to think I should already change course myself but because of the speed of the other couldn't quite evaluate to which one. By all interpretations of ColRegs I was the stand-on vessel but I was beginning to get seriously frightened, I wasn't prepared to insist on my rights, just wanted to survive, but I didn't know what would be the best strategy - to stand on with no change of course by the other could result in me being run down; to head up through to a NE course could anticipate the other vessel's possible avoidance action but the greatest confusion came because of the phenomenal speed of the other vessel and my feeling of helplessness at trying to make any manoeuvre that would get me away from such an object with my paltry 5-6 knots - I had started the engine in case I needed the last ounce of speed. My VHF transmit function had failed during my cruise so I couldn't call on channel 16. In the event, I swung to starboard and round to a reciprocal and watched incredulously as the ferry roared over my track during the next few minutes without any change of speed or course, about where I would have been if I hadn't changed course, I was then left tossing in the maelstrom of a wake that was left. Very shaken. It was a Croatian registered ship and there were figures on the bridge as well as some passengers on deck to witness it all. With my white sails in clear visibility at about 09:00 on a fine morning I must have been seen. So yes, it was "quite spectacular to watch at close range" but once is enough, thanks. BrianH. |

SOME ferries have Voight Schneider, not most, and it's by NO means a high speed drive, although it will increase maneuverability. Most of the monohull Channel Ferries have V-S,and IIRC all of the Solent ferries. BG I forgot that this was crossposted in "uk.rec.sailing". Ok, "most", over there, some over here. [snip] They float on water, they move around, some of them go fast. Wrong again. It's all VERY relevant, because what you can or cannot expect from any of the varying types is significantly different Significantly different my left foot. Observation will tel you what another vessel is doing. All well and good, but "observations" will not tell you what a particular vessel may or may not be capable of, unless you know what they have and are aware of it's plusses and minuses, and many are significantly different. For instance, at sea, underway, could you tell the difference between a "V-S" and standard drive ferry, assuming you didn't know ahead of time that the particular boat had one or the other drives? and what you don't know can get you run down. Well, if you don't know that a rapid flashing amber light indicates a hovercraft it could. Not too many hovercraft over here, so we tend to forget about them, as our major "high speed" ferries are waterjet. otn |

It's usually difficult to see the Southsea/Ryde hovercraft because it just looks like a very low-flying cloud - with an amber light flashing on top. It's about 100 feet long throws up spray & makes the noise of a Squadron of Concordes. You can see and hear it the other side of the bloody Solent! You are clearly deaf *and* blind but even then I'd have thought you'd have felt the vibrations! |
