And some people here claim displacement boats don't plane. Duh! Oz was right. Some people need to sail on one of those. I saw no displacement hulls planing . A displacement hull, by defination must be supported by buoyancy alone, and it must displace water from its path rather than planing on the water's surface. If it is planing it's either a planing hull or semi-planing hull and not a displacement hull. Joe Cheers, Ellen |

The "displacement" of a boat is the mass of the water it displaces at rest. A "displacement boat" or hull is one that displaces approximately the same amount of water regardless of its speed. A "planing hull" is one that when moving lifts out of the water and thus displaces less water than its mass would imply. |

Ellen MacArthur wrote: http://www.conradhumphreysracing.com...?articleid=211 Scroll down and it says *displacement* 8.5 tons. Now *that* was funny So?

A "planing hull" is one that when moving lifts out of the water and thus displaces less water than its mass would imply. It doesn't necessarily have to "lift out of the water" just be supported (at least partially) by the force of the water flowing under the hull. Although with some boats, the lift is pretty amazing and has to be seen/felt to be believed. "Capt. JG" wrote: Forget it Jeff. Neal is not too bright. True. In fact, the above statement is one of the most convincing that "Ellen" is really the Crapton. -signed- Injun Ear (formerly known as Eagle Eye) |

"Ellen" is really the Crapton. Jeff wrote: which statement? Saying that a spec of stated displacement was an indicator that the boat in question is a "displacement hull." -signed- Injun Ear (formerly known as Eagle Eye) |
