Seaworthiness of Mac26
"JAXAshby" wrote in message ... Modern cruising catamarans, over 35 feet and used for cruising, have a near perfect safety record, especially with regard to sinking.

While it was a "breakthrough" boat in its day, they serve now as the example of how not to build a catamaran. Try again, jaxie. |

Seaworthiness of Mac26
jeffies, owning a catamaran is a leap in religious faith, and like most
religious bigots, catamaran bigots have the mental capacity of a seven year old kid. catamarans present huge, and unstable, wind surfaces, have large, marginally structural surface unable to stand tons of water slamming against it, unable to sail up wind, enormous engineering problems in trying to keep the two hulls from twisting the interconnecting structure to broken pencils and are rather misserably slow when weighted down by cruising necessities. As a % of boats "out there", catamarans sink at a much higher rate than mono's. That is why so few catamarans -- as a % of total catamarans -- "go out there". Catamarans are training wheels, bought by people who feel the need for training wheels and both the boats and the people who buy them are best off staying close to shore and anchoring every nite in a well protected anchorage. now, jeffies, go pray in your Church of Eternal Life/Two Hulls that the God of Two Hulls might smite the Half-Boat Heathens who might dare to set sail in winds above 15 knots and waves above 4 feet.

Poor, poor jaxie. Your post reeks of jealousy.
You still haven't given even a single example of a cruising cat problem.

The existance of a few bad small cats is enough to condemn all multihulls in his tiny mind despite the existance of cats which are unconditionally stable. |

yeah, the asshole believes in science, facts, experience, limits of positive
stability, structural integrity and 30 knot winds, too. killfile the *******. Poor, poor jaxie. Your post reeks of jealousy. You still haven't given even a single example of a cruising cat problem.

the existance of cats which are unconditionally
stable. "Unconditionally stable" is a term recognized in maritime parlance as hyperbole. in maritime parlance perhaps, but to the rest of the world it is referred to as "bullsh*t". Only drivers of training wheels think otherwise. |

There are, of course, some deliberate design choices such as a relatively short mast and sails which are calibrated to offload dangerously high forces before the craft is in danger. |

"Unconditionally stable" is a term recognized
in maritime parlance as hyperbole. Only by those who fail to understand the designs involved. such as design engineers? unconditionally stable means stable without an condition contradicting it. Catamarans are usually UNstable in conditions beyond about 30* of heel. In fact, catamarans are most stable ONLY at zero degrees of heel. Each degree of heel past zero takes less and less force to push the boat to the next degree of heel. In addition, as the windward pontoon clears the water the wind force heeling the boat *increases* due to the end plate effect of the leeward pontoon. Both are in dramatic difference to monohulls, which in cruising designs are more resistent to heel as the boat tilts (up to about 60* generally of heel) and in which the sail area exposed to the wind decreases. Catamarans can be capsized by strong winds alone. Monos virtually always require breaking waves to capsize. There are, of course, some deliberate design choices such as a relatively short mast and sails which are calibrated to offload dangerously high forces before the craft is in danger. |
