Plaining or Planeing?

Thats a lot of questions...but I'll take a stab at some..

Plane i'm almost certain..

Water has mass, and must be accelerated out of the way of the boat. Force = Mass Acceleration, so more acceleration of the water (or more water moved) , is potentially more lifting force. but

The boat when planing displaces enough water so that the boat's weight equals the total forces created accelerating the water downward. Take the summation of downward water acceleration vectors, all functions of the angles and masses of water involved, equals lift; then the water that has lateral acceleration vectors atributed to them is, waste drag and do not produce lift.

Whew...

Have your seen.

It is well know that

Women = Time X Money

as well as

Time = Money

So substituting for Time,
Women = Money x Money = Money^2

It is well documented that:
Money = Root of all evil
Square both sides, so
so Money ^2 = Evil

Therefore it verifies

Women = Evil

I knew it and that equation proves it. Men do everything, including go to war, because of women. Heck, if it wern't for women, I wouldn't even wax my boat. That alone is poof 'cause I hate waxing my boat.

Beware of the evil that lurks on the lakes and waterways and in the backs of CCs (like mine when I'm lucky).

I guess it depends on how much of the hull needs to be out of the water to consider it to be planed out>?!??

The definition of a planing hull is one that crests and rides in front of its own bow wake unlike large yachts or ships with a full displacement hulls that push their own bow wake.

Good call by 64 Skier on the semi-displacement hull....How do you tell your hull type? The bottom of a planing hull viewed from the side will have striaght lines or grow as it approaches the stern while a semi-displacement (semi-planing) hull will incline slightly as it approaches the stern. With the semi-displacement hull you get the best of both worlds. Speed and great tracking

Here you go guys. The speed at which a boat begins to Plane, is when the boat begins to exceed the maximum hull speed. The reason a boat begins to plane is because it begins to "climb" out of the hole that the boat makes in the water. the maximum hull speed is the maximum wavelenght that the boat can produce with its length. Here is the equasion. Hull Speed = 1.34 * (LWL)1/2
LWL - Length at Waterline.

Mustang 17
LWL = about 15.5
[(15.5).5]*1.34 = 10.38

A Mustang 17 begins to plane at 10.38 mph.

This also explains why your boat planes later if you have a bunch of weight, or have people up in the bow....your LWL increases.

The formula obviously gets more complicated but this is a quick easy version we use in the sailing community to determine how fast a full displacement hull will go.
