Correct Tab Application

[1960 Cutter Runabout]

Hello-<br /><br />I have a 14' runabout that leans to one side when only one person is in it. Because of where the driver sits infront of the steering wheel the battery is on the same side and the only thing of any weight on the other side is a 6 gallon gas tank. Would trim tabs or smart tabs help in this situation?<br /><br />Thanks-<br />Dave

Re: Correct Tab Application

on a fourteen foot runabout? I'd save your money and do some weight management.

Re: Correct Tab Application

You can adjsut Smart Tabs to compinsate for the list. Also, we make Trim tabs for boats as small as 9' and as little as 6 HP. When people ask if Trim Tabs will help a small boat, the answer is always YES! The improvements are even more dramatic on small boats. Besides, it is like say that a 747 jumbo jet needs flaps and the Piper two seat 150 does not.

WHA!! Do you even know what flaps do on an aircraft? what is a piper 150?

Re: Correct Tab Application

Thanks for the replys.<br /><br />Sloopy, You are correct that my problem is caused by uneven weight distibution, but when I am in the boat by myself, the only items with any weight are me (215 lbs), 12 volt battery, and 1 or 2 - 6 gallon gas tanks. There isn't enough stuff to move around to offset me.<br /><br />NautiJohn, if I install and adjust Smart Tabs to compinsate for the list, what happens when someone gets in the boat with me? Would I then need to re-adjust the tabs to prevent them from causing a list in the other direction?<br /><br />Thanks-<br />Dave

Yes..he does.<br />And a 150 Piper is a super cub....<br />Do "you" know what flaps do???

Analogy<br />From Wikipedia, the free encyclopedia<br />Jump to: navigation, search<br /><br />Analogy is either the cognitive process of transferring information from a particular subject (the analogue or source) to another particular subject (the target), or a linguistic expression corresponding to such a process. In a narrower sense, analogy is an inference or an argument from a particular to another particular, as opposed to deduction, induction and abduction, where at least one of the premises or the conclusion is general. The word analogy can also refer to the relation between the source and the target themselves, which is often, though not necessarily, a similarity, as in the biological notion of analogy.

Re: Correct Tab Application

Cutter;<br /><br />The first thing I would do is install the tabs without trying to compensate for the list. You may find it is not necessary. To be more specific regarding the addition of another passenger, adjustment should not be required.<br /><br />What you should keep in mind is that the boat will always lean one way or another for a bunch of reasons. Side to side, front to back, corner to corner. What you want is to make this as comfortable as possible. Adding other people will be similar to adding additional passengers to a vehicle. Depends on the vehicle, and the passengers.<br /><br />In short the boat will perform and handle much better in all respects.

The 747 has a wealth of high-lift devices because of the shape of its wing and the aerodynamics involved with high speed, high weight.<br /><br />The Piper PA-18-150 Super Cub, which generally doesn't need flaps, also has them for enhanced performance in various takeoff and landing scenarios.<br /><br />In both instances, wing shape and aerodynamics dictate the use of flaps and size alone has little to do with it. Marine example? A 26' Grady would probably benefit from tabs, a 26' Glacier Bay would probably not because the hulls are different animals.

Re: Correct Tab Application

Old C;<br /><br />There is a valid similarity between the variable and controlable surfaces on an aiplane, and variable and controlable surfaces on the hull of a boat. I use the analogy simply because the variable surfaces are "accepted" on small planes but not commonly accepted on small boat hulls. The ability to adjust the hull design to suite the situation and / or condition makes for very significant improvements.

Re: Correct Tab Application

PA-18 is how you refer to a super cub, the 150 is for 150 horse power. No one ever calls a super cub a piper 150! Cessna used to make a cessna 152/150 both with around 100 horse power, the main difference in the two models being the cabin width and the engine type (Continental or Lycoming) and lots of smaller differences. Flaps on aircraft allow for a slower landing speed and in many small aircraft will pitch the nose down (150, 152, 170, 172, 175 ect ect....) The flaps will also give you a higher decent rate. They do not necessary provide more lift, on many aircraft you would be unable to climb with full flaps. Some aircraft will also use flaps for take off (they can also be used for soft field take offs on smaller aircraft to get the nose off the ground faster) this to allow the aircraft to become airborne faster and lessen the runway needed to take off. <br /> A much better analogy to tabs on a boat would be the trim.

Re: Correct Tab Application

And also a 747 has slats and flaps, a pa18 has a simple flap mechanism, which actually could easily be compared to the smart tabs (anyone who has knows how the flaps in a pa18, or 170a will know what I mean.)

Re: Correct Tab Application

Well actually now that I think about you could not compare the flaps to smart tabs, only the spring thing...
