Open 60's are a displacement boat? Shirley you jest!

Scroll down and it says *displacement* 8.5 tons.

Cheers,

So? 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.

Now *that* was funny

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.

True. In fact, the above statement is one of the most convincing that
"Ellen" is really the Crapton.

Saying that a spec of stated displacement was an indicator that the
boat in question is a "displacement hull."

Duh! And what's wrong with saying that. Every hull that floats displaces enough
water to float it. It would sink if it didn't. So every hull that floats is a displacement
hull. If somebody says no it's not a displacement hull! It's a planing hull. That's wrong.
It's a displacement hull that's going so fast it's planing. If you have a submarine it
has a hull. When it's floating on top of the water it's a displacement hull. When it's
under water it's a displacement hull weighted down enough to sink it. The same's
true for a open60. When it's planing it's a displacement hull planing. Just like the
submarine's a displacement hull sinking. Both of them never stop being a displacement
hull. So you think something that weighs tons can just all of a sudden stop weighing
anything because it's skimming along the top of the water?
Did you ever skip flat rocks across the water. The rock will skip so you could
say it's a planing rock. But it will sink when it stops so it's not a displacement rock.
As long as a hull planing doesn't sink when it stops it's a displacement hull.
Now you tell me what's wrong with me saying if a displacement is listed it's a
displacement hull? If it displaces so many tons of water it's floating and displacing.
That's a displacement hull. You lose Mister-Know-It-All.

Cheers,
Ellen
