I/O boats will always go in the direction the drive is turned steering works better then shifting. For one reason or another most boats have one engine that never dies and one that can be finicky, I always told my clients do your docking with the finicky one, if it craps out there is -0- panic simply grab the reliable ones shifter and finish docking. Using that practice has stood well by many of my customers over the years, try it many will find it may make your life easier.

Great post. A 26 footer is probably an 8 foot beam and the I/Os are probably close together. Add that to the fact that the props extend so far behind the boat (as opposed to inboard screws which would be closer to midships) and you are better off docking a narrow twin I/O on one side.

Let the combined effect of the wind and current act as one screw, and use one side of the boat to counter that force= the ability to go zero to one-half mile an hour around the dock.

Using the trannies/screws for manuevering works great with fat cruisers with widely spaced screws far inboard of the transom.
But not for small I/Os.
I have a 26 footer with twin I/Os and I dock on one side.

Tres goes over some great fast drift docking tips that helped me out greatly.

Also, Boating mag has an article about a docking tournamnet in MD with some great tips as well.

Are boats with drives/props set to turn in vs out when going forward more difficult to back up ?
I have a very difficult time backing my boat with this set-up.

I would't shut one engine off. If you can't dock it with the sticks and you have to dock it like a single, at least keep it running. Only one engine with a power steering pump.

If the boat isn't a staggered setup, using the sticks works just fine. I leaned on cruisers from 25 to 43 footers as I grew up. Making the transition to a 36 pache was no problem at all.



Practice!!!!

First of all... a 36 Apache is NOT a small I/O.

If you learned on cruisers you know that a boat with I/Os just can't leave a seawall sideways like a cruiser with twin IBs and rudders.

There is a fundamental difference between having the props under the boat and spread versus a couple feet behind and 18 inches apart.
Plain and simple. There are moves that I can make with inboards that I can't possibly make with I/Os.

But I'll keep practicing jeff.

Re: twin engine docking tips?
 
I explain our situation, not everyones. But it can be done relatively easy with a 36 foot fast boat with I/O . I wouldn't dare try it with one drive only.

Every V hull I've driven with inside rotation
has handled poorly around the dock.


The difference appears to be whichever one is in
reverse, it doesn't seem to have much "pull".

The only thing I can factor to this is that the water
off the props ( on the keel side of the drives) are
being thrown upward, and hitting the V portion
of the transom, reducing total reverse thrust
of that prop.

DO NOT APPROACH THE DOCK FASTER THEN YOU WANT TO HIT IT! :eek: :eek:

Rule one above

Rule two below.
Don't hit anything any harder than you are than you are willing to pay for! :drink:

I read a small piece on docking and the author said to imagine yourself standing in the middle of an X. If you do this, you will always know which drive to engage to move the boat the correct way. This is very similar to sydways info above and it works for me.

Netural is your friend. I don't know how many times I've said this to my wife as she's learning to drive as well.
