Typical Neal gibberish to hide is total ignorance of nautical science. It really drives
him crazy that there are people who understand naval architecture as a science and are skeptical of crackpots who make it up as they go. -jeff - Two Motors for Two Hulls! "Simple Simon" wrote in message ... And you, Jeff, like the majority of pretend sailors here, consistently fail to remember Rule 1 which states "First she's a sailboat". Any and all discussion of volume and or displacement of water which boils down to mass can be more simply stated using LOA since ballasted monohull sailboats all fall within a predictable range of mass. When one keeps Rule 1 in mind at all times it becomes increasingly evident that everything - yes, even motors (some absurd people have TWO of them) come second, third, fourth etc. It follows that since 'first she's a sailboat' that any and all motors are intended to be a supplement and only needed for flat water when there is no wind. Any and all other reasons to use your motor(s) that require such ridiculous levels of HP and weight violate Rule 1. This cannot be argued. S.Simon - keeps his priorities straight. "Jeff Morris" jeffmo@NoSpam-sv-lokiDOTcom wrote in message ... Sorry about the late reply - I'm just catching up ... Your claim of "one horsepower for every foot of length" is absurd and shows a remarkable lack of understanding of nautical science. Required HP is not a function of length, it is a function of displacement. The Simplistic way to remember this is that moving the boat requires pushing aside a volume of water equal to the displacement. The rough rule of thumb is that one HP for each 500-600 pounds of displacement is required to push a boat to hull speed. For a Coronado 27, this works out to about 10-12 HP. For a Hinckley Bermuda 40, a boa t Bill Tripp would prefer to be remembered for, this is 40 HP. The newer H42 displaces 23,500 and has 50 HP; the 51 displaces 40,000 and has 88 HP. All perfectly appropriate. Remember that diesel should be run at 80% rpm, where the output is considerably less than the rated power. So how does displacement vary with length? This is roughly a "cubic" function. The "Displacement/Length" ratio is roughly constant for a given design style, and is usually computed as "Tons / ( (WL ft/100) **3). Thus, a boat twice as long will displace 8 times as much, and require 8 times the HP. This fits in with the boats listed. Once again, Neal has displayed mathematical and scientific skills consistent with his education as an English major. -jeff "Simple Simon" wrote in message ... Dear Ms. Carroll You're beginning to catch on, Mam! Of course, any boat that has more than one horsepower for every foot of length in NOT a sailboat. It is simply a motor boat with spars. The very best it can be called is a "motor sailer." Think of how absurd the very idea of 50 horsepower in any 42-foot motor boat with masts really is? It only takes 20 horses to drive that particular Hinckley to hull speed. So, why all the extra power and weight? The answer is simple. It's because the boat is designed to motor and charge huge battery banks to run all manner of unnecessary crud that really has no business aboard a sailboat. Nobody but rich, ignorant snobs own Hinckley's anyway. Hinckleys are an example of a boat that is way way way overpriced for what you get. Only rich ignorant snobs spend so much money on a name. These same people wear Rolex Oysters not because they keep any better time than a cheap Timex but because they think it gives them status. Well, the bottom line is their boat and wrist watch are only owned so they can feel good about themselves. For the most part these people are no different than Bobsprit except they have money to burn. They think brand names mean everything and since they can buy pretty much whatever they want they buy things they think will make people the most envious. Little do they realize real sailors laugh at them and their ignorance. Real sailors know what these pathetic individuals are all about. We laugh when we see them motoring their so-called sailboats around expecting folks to ooh and aah! Would that they were more honest and just bought a motor boat in the first place. S.Simon - has more common sense than most people "The Carrolls" wrote in message .. . So a Hinkley Sou'wester is not a sailboat? 50 hp at 42 feet. "Simple Simon" wrote in message news ![]() "Kelton Joyner" wrote in message ... So, a 38' Cabo Rico is not a sailboat? BS. A Cabo Rico 38' is, indeed, a motor boat with sails unless someone had one commissioned without motor. Any sailboat that has a built in motor with more than one horsepower for each meter of length is a motorsailer at best. What's a Cabo Rico 38 have? About 40-50 horsepower? To be a sailboat it would have to have no more than 12 horsepower. S.Simon |
