Docking by Yourself at a T-Dock -- with new and improved photos

At many marinas they have what is called a "transient" dock, or T-dock. Often it is literally shaped like a T, in that your boat comes along side the top of the T. The boat is only secured on one side.

You might be by yourself, or we can use the example we used before that your sailing companion has injured himself and is sitting with ice on his ankle. You're going to have to secure the boat yourself.

As you glide up to the dock in neutral, make note of the wind direction. If you're coming up on the starboard side of your boat but the wind is coming across the starboard side, you have to get the bow and stern secured rapidly. It doesn't have to be beautiful on first pass.

An easy way to do this is to attach a long line (at least twice as long as your boat) to your stern cleat. Have the boat in neutral but still gliding slowly forward. As you glide up to the dock, just throw the line over and behind what will be, temporarily at least, your stern piling. Keep hold of the bitter end as you do this. Don't tie any kind of knot -- just let it lie behind the piling.

Walk to the bow and throw the line over and behind another piling near the bow, again hanging on to the bitter end, and lash it off at the bow cleat.

Clearly your boat is not permanently tied up now, but the wind can no longer blow it away from the dock. With the boat temporarily somewhat secure, it's now easy to tie the boat up properly, taking your time.

Since I often bring my boat up to a one-sided dock, I have a long line (120') permanently fastened with a baggage tie knot  (sometimes called a cow hitch) to my toe rail, about amidships. A stanchion will work well if you don't have a stout perforated toe rail.

I keep the line divided in half with each half separately hanked, hanging from the life lines.

Total length of this line is 120', attached to toe rail with a baggage tie at the middle of the line,
with each loose end separately hanked.

Take one end of your very long line (the one attached to your boat with a baggage tie), and attach it to a piling between midships and bow with a clove hitch.

Clove hitch used around a piling allows one line to be used both as spring line and as bow or stern line.
The bitter end of that line goes up to your bow cleat. Undo your temporary line from that cleat, throw it on the dock, and cleat off the new line. You have now used half of that baggage tie line as both spring and bow line.

You'll repeat this process with the other half of your very long line: first use it as a spring line with a clove hitch at a piling between amidships and the stern, and then take the bitter end to the stern and attach it with a cleat hitch. Gather up your temporary dock line, re-hank it and stow it. You'll need it again when you leave this dock if you don't have someone helping on the dock.

Now you can see exactly where to put your fenders and fender boards to keep your boat off the dock. I do recommend that you set the boat so you don't have any stanchions pressing up against pilings.

So what if you have to get away from the dock by yourself? Once again, study the wind direction. If, for instance, your bow is pointing to the west, if the wind is from the north it is possible that if you just put a temporary line around the rear piling and your rear cleat, the wind will blow your bow in the direction it needs to go while you keep the boat near the dock with that stern line. Or it may be best to just pull forward, turn into a fairway and turn the boat around. It will vary according to wind, current, and your boat's characteristics. You want this line to just be a single loop around the piling so you can remove it easily as you leave the dock.

One thing is for sure, though, you won't want to be wrestling with 120' of line, tied to pilings with clove hitches, as you try to exit. Keeping line out of the water has to be of paramount importance. Let that line get wrapped around your rudder or propeller and you'll be at the dock longer than you expected!

So just reverse the process. One cleat at a time, replace your very long line with a line just laid behind the pilings and latched on to your cleats (just as you did when you first came alongside the dock). This time, you can use a "half cleat hitch" on your stern and bow cleats. (If this knot has another name I would love to hear of it). 

It's easily made. You lead your line to the cleat, but the only part of the cleat hitch you use is the very last turn of the line, when you make a loop and twist it before hooking it over the horn of the cleat.

 Step 1, with the red and white line laid around the cleat.


Step 2. You'll make a loop with the right end,
pull it around the cleat, twist it, and slip it over the left horn
of the cleat. Your half-hitch on a cleat is complete.

This makes a working knot that will hold well but that can be undone rapidly and easily. 

Standard cleat hitch
 Just for reference, compare that quick, temporary half-cleat to the full cleat hitch below. You should use the full cleat hitch when the boat is fully secured at the dock.

Hank your very long line and re-hang both ends from the lifelines. You don't need to be tripping over it as you move along the side of the boat -- or worse, have a long line trailing in the water when you know the propeller wants to get to know it better!

When you're ready to release that temporary line, use the wind to judge which end to undo first. We'll say it's the bow, and that the wind is going to catch the bow, and spin the boat slowly around until the bow is pointing toward the east instead of the west.

Put the engine in neutral, release the half-cleat hitch on the bow, and throw it on the dock near the stern. Get back to the cockpit, and start pulling the line in around the stern piling, holding on to and working both ends so the extra line goes onto your boat and not into the water. When the boat is turned, pull the remaining line in (keeping it out of the water, very important since it's near the stern), put the boat in forward and drive away from the dock with the wind at your stern.
