Floating dock and creaking lines

We were docked starboard side-to on a floating dock this past weekend. Bow into the wind, because the nearest power pedestal required it. We had some very strong winds during the night and that led to the bow being pushed hard to port. This put a fair strain on the starboard lines, leading to creaking where they passed through the fairlead on the way to the cleat. This was especially bad at the bow cleat right above the forward stateroom where I was fitfully attempting to sleep.

There was enough force to the wind to likely have pulled any sort of in-line snubber taut.

I did manage to quiet it down some by pouring water on it. This worked until the howling wind managed to dry the line out again. This was happening with both a new and an older braided line. The older line was at the mid-ship cleat and was also creaking badly.

Any suggestions on how to deal with this situation in the future? Besides moving the boat, of course. That would not be practical in that kind of wind or a transient slip situation. Not to mention it being 3am.

I always use 3 in 1 oil to stop my lines from creaking. Just kidding! Don’t do that.

Falcom mooring compensator. I believe that is what they are called. The stretch so the lines donít draw up tight with a bang.

Doesn't matter,if he 2 parts the lines it will solve the problem Mark. Dish soap and water are great but if you want to sleep, 2 part them.

The wind was strong enough that I think it would have pulled the snubber tight, effectively rendering it useless. But I think I still have a snubber like that in storage. I'll drag it out and keep it onboard should I run into the same kind of problem again.

2 part? I've not heard lines referenced that way.

During one attempt to fix it I did add a second line at the bow. But there's only one cleat up there so the line had to go through the same fairlead, resting against the line already present. The 1st line was leading to a cleat almost directly beside the boat, down near the waterline on the floating dock. The second line I added at 3am led forward to another cleat on the floating dock. Adding it did not change the noise problem, but did at least give me another attachment given the very strong winds.

I suspected dish soap might be a possible fix. Didn't want to go clattering through various cabinets to find it at 3am. Better that than oils or vaseline. These were the lines we use for traveling, so I'd prefer to avoid gunking them up with something hard to clean.

It was the line being pulled tight where it goes through the metal fairlead on the wood deck rail that was making the noise. Where the red arrow points in this picture. The starboard size has red ovals highlighting where the fairlead is located and the cleat on that side. That picture was from another day, but it shows the same line direction and point where the line was making noises.

It sure sounds like a day you might double up the lines, but I wonder if some form of protective cover where it passes through the fairlead might help. They sell here in packs of ?4 as "Gropes"(sorry brand name lacks PC, but there it is).

Three strand is quieter. Braided line seems to make more noise (IMO)

There are rubber chafe guards that might quiet the lines.


Plan B might be heavier dock lines that do not stretch from the wind load.

My anchor snubber would creek where it came on board with chafe protection sleeves. Changed sleeves to chafepro brand, no more creeking as they stretch.

Maybe an option for you. Can’t explain why, just noticed it, and am thankful.

Use the rubber snubber. Doesn't matter that the thing runs out of travel as long as it is the right size for the line. It will do its job.

Just do not over wrap the line onto it as I have seen many do. Instructions clearly say no more than three complete wraps but I see 4 or maybe 5 and then they will tear. I put on two wraps and that was all I needed.
Done correctly they will have a long life. SOme of mine are pushing 20 yrs.

It will take the shock out of the boat when the lines run out of stretch. I was faced with a similar situation and doubling the lines did not help. Squeek and sudden abrupt pull up was causing trouble.

I was just lucky. The marina I was staying at had two for sale so I bought them. Once installed the shock disappeared and the noise was far less.

Now all my permanent dock lines sport them.

That is because the 3 strand stretches more than double braid. I suggested using a mooring compensator because they allow stretch. We were at a marina with a long ago boat that had lots of wind. The boats would hammer against the dock lines badly. I put on 4 mooring compensators and the ride was completely different, no more jerking and a lot less noise. People would notice how much differently our boat was riding and soon almost all the boats in the marina had mooring compensators.

I use Brait (brand name) and have no troubles w creaking.
My fwd mooring lines have a anti-chafe heater hose where it passes through the chock.
I would think the spring lines would creak more.
Maybe I have some creaking and don’t notice it.

I have these Falcon snubbers with 3/4Ē line . They are a little overkill but they work .

would there be a way to tie off from your pulpit ? That way you would have a straight line from your boat to the dock with no chaffe/inflection point.
