I see you have decided not to argue against the facts for a change.

There may be hope for you yet.

Idiot boy, do you not think that a PROPERLY TRIMMED boat, ie: weight
distribution, would out perform the exact same boat that was not
trimmed properly, but instead used trim tabs?

No, it would not. Equalization of weight would not outweigh the
advantages
of the lift provided by trim tabs.

Let me ask you a question, if a boat with trim tabs is able to plane at
20
knots with the tabs adjust correctly, but must achieve 30 knots to plane
without tabs, will adjusting the weight distribution in the boat allow
the
boat to plane at 20 knots as it could with the tabs?

Again,dumb JoeTechnician, you were speaking of EFFICIENCY. I don't
give a damn about the speed at which the boat planes. I'm telling you
that if you stick a couple of plates in the ****ing water, and drag
them THROUGH the water, you are creating drag. You will use more power
to plane at 20 knots because you have to drag those plates through the
water. Does pulling a skier make your boat more efficient, too????

You can do the exact same thing with an aircraft, you can either trim
it out by distributing the weight properly, which then you don't need
to use tabs to trim it, or you can stick trim tabs out in the air.
Now, which would YOU think more fuel efficient??

Do you really think the dynamics of an aircraft flying through air is
the
same as a planing hull on water?

Never said they were the same thing, but, there is a direct
correlation between tabs on an aircraft, and tabs on a boat. Thusly:
they both create drag. They both create lift. BUT again, at a cost.
Same thing with an airplane, you generally use some tabs for takeoff,
because the lift is so much better. But, when you get up to altitude,
you certainly don't use the tabs because the efficiency of dragging
them through the air makes fuel consumption rates rise.


You're forgetting something, when tabs are deployed on an aircraft, and
produce lift, efficiency does not increase because the density of the air is
equal on all sides of the aircraft. On a boat it is much different, water is
approximately 800 times more dense than air and any reduction in wetted
surface will always result in increased efficiency. Properly activated tabs
reduce the wetted area by providing lift at the stern, planing the boat, and
lowering the bow reducing the hill of water the boat must overcome. Add to
this the more efficient prop angle which reduces prop slippage and energy
wasted pushing up instead of forward and the overall efficiency of the boat
is greatly increased.

It's obvious that you have never owned a boat with trim tabs. I suggest you
go along for a ride with someone who does have them and observe them in
action.
