skegs on a step bottom boat ?

[Offshore Ginger]

Hey guys , like i said in a later post when i was employed at Skater we put a few skegs or ( Keel Daggers ) as Pete would call them on mostly 40's and basically the reason for this was to assist in turning on a coarse like Key West during the world's .

You would not want to see what happens on a full size boat if a turn fin left the water due to a wave in a hard turn. An RC boat will sometimes do 2 or 3 360's in the air before touching the water again. The only thing I've ever seen close in a full size boat was a Checkmate at almost 100 and the stock steering broke.

merc lengthened the skegs on the 6's and the ITS drives, maybe they're not long enough with the extremely high X's the stepped boats are running these days. The air bubbles are like ball bearlings under the boat.

Skegs are for turning. If you guys want to stop the spin outs start by lowering your drives back in the water.

I know I'm late to the party tonightm but...........

What the he!! are you talking about????? Diff breed of boat dude.:sifone:

I went from a jet ski to a twin engine, twin step boat,I have never driven a single engine boat.I have never had a problem because I WAS TAUGHT by someone who new what they were doing and understood theory of how a stepped hull works.If you do not know where to put your drives you are not going to find out on this or any other message board you need to call Tres or Brad.It is really not that hard.There is a lot of incorrect information on this and the other Cigarette thread about trimming a stepped hull

If you do not understand how the hull works you will not be able to adjust quickly to changing situations and also not be able to recognize when the boat doesn't feel right and why.We have a conversation like this every time there is an accident

 

[phragle]

you want the ultra simple yet incredibly complicated answer?? All you do is hinge the bottom of the boat...push a button, you have a conventional Vee, push the button the other way, the hydralics take aver and insta-step.

 

[Tres]

Skegs on the bottom? Nope/ Longer skegs on the drives? Not really. You need to know what is happening under the bottom to drive without incident. Thats all. You will spend more money on that crap than our course. Go figure

 

[Magic Medicine]

If you can afford most of the powerboats that have spun or flipped recently, the price of Tres course is s a drop in the bucket! If you want to run hard on a "super fast" boat take the course!

 

[Geronimo36]

I agree, take the course.

An manufacturers, do more work to make your boats safer. There are certain boats that are more prone to spin-outs than others!

Seems like a good idea after reading about all these step bottom boats spinning out lately.

Maybe people should just learn how to drive a step bottom boat ???? Dave

This is a pretty good shot of a skid fin on an unlimited. Note the size and the position. Also keep in mind that these boats are very light and have a VERY low aspect ratio- (height to width) and an exceptionally low center of gravity. Plus they have no relative roll when compared to a vee.

Now, watch this video and imagine how a skid fin might help. This is typical of what's going to happen to you in a step boat.


On an unlimited, if they get bounced up in a corner they'll jump sideways until the fin catches. On a vee, you can see how when the rear loses bite the boat slides right, catches and rolls from hard left to hard right.

Question for the pros.....

Does a multi step like an Outerlimits, vs a dual step like a Black Thunder, vs a single step like an Intrepid handle completely different from each other?

Yes, it's all about the placement of the steps, number, depth, drive height and various other variables. Each design is different and some are more prone than others.

 

[MarylandMark]

Really to go one "step" further each and every boat has so many variables each and every one of them handles different.

One hull with a covergirl cabin and the same hull with a full cabin; they will drive different

 

[BradH]

The Throttle-Up/LA Marine boat (Steve and Lee) has retractable fins in each hull. Neat little setup.

 

[glassdave]

Some trim tabs have rails on them designed to help.

I personally think it is just case of learning the boat. You can not make it turn harder then it wants too. So you add a ski fin so it doesn't slide, it just throws you out instead when you turn it too hard. Experience and an understanding is what is needed not a turning aid. IMO
