“We owned a 33’ SeaRay Sundancer Twin Inboard for years.” Pat told us as she explained her docking story. “Then, we downsized to a 28’ Formula Sunsport Twin Sterndrive. We thought we could bring our docking skills with us and continue enjoying boating. Out on the water wasn’t so bad, but we couldn’t dock it. It just didn’t handle the same.
We almost hit other boats several times when trying to dock. Everybody said to tie the bow line first, but that doesn’t work for us, because our side decks are too narrow making getting to the bow almost impossible.
We are so stressed about docking,
that we have only put 7 hours on the boat last year and considering getting out of boating all together.
I went on the internet to all the docking sites, docking aid sites and then found your site. I found more information there and decided to order your Twin Sterndive Lesson and Video, but wanted to talk to you first.
When I called, I learned more in that conversation than everything I had learned so far about docking a Twin I/O. I ordered the Twin I/O Introductory Lesson and the Video.
I was so relieved to know that I was right about not tying the bow first. It just doesn’t work and I can’t understand why everybody says to do it.
You told me your FLIPP Line procedure would eliminate the stress and fear of docking and that’s what we need. We are stressed enough at work and want to get away from stress—not move into another stressful situation.
Previously, we even had a Mega Yacht Captain come aboard to teach us to dock our 28’er and he couldn’t do it. He said the boat didn’t handle like he expected. He was absolutely no help to us at all. I was ready to buy a gadget to help get the line around the dock cleat or ballard and/or have a bow thruster installed.
After my conversation with you, I realized that I didn’t need any of them. I could just follow Dawson’s procedure and I would be able to dock effortlessly and stress free making boating the fun it’s supposed to be.
No one has been able to tell us how to dock a Twin I/O, except you and your method works!”
Thanks Pat for your story. This problem is common among boaters who buy a boat with a drive system different than they are accustomed to.
The Captain of the Mega Yacht, like so many boaters, assumed that his Twin Inboard method of docking would naturally work on this little 28’ twin sterndrive; but, he obviously didn’t realize there is a difference between inboards and sterndrives.
Just because a plumber has teeth, doesn’t qualify him as a dentist.
Moving from a twin inboard to a twin sterndrive requires learning all over again. Different docking and handling techniques are required.
Twin Inboards have fixed shafts and propellers (non aimable) under the hull. The propellers are fitted to the shafts that extend on an angle through the bottom of the boat. The motors are fully inside the boat and are hence called inboards. The rudders that are placed behind the propellers (also under the hull), deflect the propellers' thrust for steering in forward. In reverse, the rudders rely on the water passing by them for steerage.
Twin Sterndrives or I/O's are drive systems that are a combination of inboard engines connected through the transom to outdrives. The package is known as a sterndrive or an Inboard/Outboard or an I/O--Half in and half out. Sterndrives are not direct drives as some people call them.
The motor portion is totally inside the transom The outdrive portions are mounted outside the transom, positioning the propellers well aft of the transom of the boat. The drives turn to direct the propellers' thrusts for steering. In both forward and reverse, the drives and thereby the propellers, are aimed the direction you want the aft of the boat to be pushed or pulled.
They are two totally different systems with propellers in totally different locations relative to the hull--totally under the hull versus totally behind the transom. The propellers are fixed or non-aimable versus aimable. Therefore, it only stands to reason that they wouldn’t react the same way to the wheel, throttles and shifts.
