This is driving me crazy !!

As PSC's have these very nice bow hawse pipes for running lines thru, my docklines naturally run from the bow cleats thru the hawse pipes to the dock cleats. I use cotton firehose type material for chafe.

Problem is when I am in the V-birth the tension that gets exerted on the dockline as the boat moves in the slip translates into noise as the dockline rubs the hawse pipe under tension.

It feels like I'm in a speaker box. It's quite loud and I'd imagine most of you know exactly the sound I'm speaking of. Or perhaps you all know the secret. If so, can anyone enlighten me on a good means to eliminate this noise? Would leather chafe make the difference? I've even imagined some form of teflon to use as chafe but that doesn't seem practical or possible.

Best to all !

Keith,

I use the corrugated looking rubber hose from West Marine. Corrugated on the outside but smooth inside. It is a lot bigger diameter than the dock line. I think it is designed for the head.

I don't hear any noise at all from the docklines.

I've used liquid fabric softener on ropes and docklines in the past to keep them both supple and quiet, this might reduce a large proportion of the noise you are hearing. Is your noise a creaking from the lines themselves or a rubbing between the lines and hawsepipe?

Two things...

1) the sound is likely caused by the line stretching as the boat moves. Try New England Ropes - Product Details this should eliminate any stretch on the boat.

2) most chaff guards and certainly anything waterproof (like hose) prevent the line from cooling properly and lead to premature line failure. Better to go without.

i do not tie my boat so tight as to require antichafe or to make noises.
noises means damages.
i allow my boat to ride comfortably with a slight amount of play. no noise. NO CHAFE. i have used same docklines now thru 18 ts and 2 furycames. no chafe whatsoever.

Aaahhh.... the dreaded 'GRONK'! ;)

Tying the boat up with a bit of slack can help ease this some.. but if there's wave action or strong breeze you'll eventually fetch up with tension again anyhow.

We've found the worst for noise was using low stretch line (like old sheets) for mooring lines. Good nylon seems quieter. Cloth rags under the contact point reduced the noise as well. In extreme cases I've mover the lines to stanchions and pulpit bases to avoid the 'dragging' line through a chock or fairlead/hawse, but you need to be sure it's adequately strong. A bowline loop on polished stainless will 'gronk' much less than a round turn and hitch, which will tend to 'roll' around the post with alternating tension.

Tough to sleep through, that's for sure!!

Dude you're not alone. I'm never tied to the dock, but it happens at anchor and mooring in any wind and it does make a lot of noise in the V-berth. It hasn't bothered me enough to take action - yet - but just last time I did think I would stick something else in there to make it stop. It is as bad or worse as halyards in a gale sometimes. Loud.

this noise would happen whether you were tied tightly or if you gave her her head a the dock. ANytime there is tension through the hawse hole it starts "squeaking".

Try the rubber. I also use that same chafe material you use on my 3 strand, possible that other highly rated chafe product or double braid might change it. Not sure what it is called, it was in the press within the last few years, black I think, less friction maybe.

All excellent suggestions that I will try. I have however experimented with different types of line. The squeak comes as the line becomes taut in the pipe and then suddenly slips/drags/rubs the contact point of the hawse pipe. I'm going to start of with fabric softener as I've heard of this before. I have tried securing loosely as well as tight with no large improvement. I am determined to get to the bottom of this. Seems I always think of this most when I'm 1/2 awake wishing I could get to sleep.

The corrugated hose sounds interesting as well as the New England Ropes.

Thanks to all !

Side note: Called Thumper at PSC this morn as I'm considering changing from the sole mounted table set to the bulkhead version. Would certainly open up a ton of space. Anyone make this conversion? Anything good or bad to say about it? I know I should probably start another thread but I'm throwing it out there. I'll bet its pricey !!
Thumper is darned knowledgeable.

Thanks All!

a. I treated many of my lines with water repellant made for climbing ropes. It replaces the spinning lubes and stopped all of the squeaking under load, even in an ancient mainsheet. By reducing internal abrasion, it extends the life of older lines. Also, the product goes a LOT further than the label says; just keep using what's left in the bucket for more lines.

Wash in waterproofing for rope | Rope Proof

In some ways it is like fabric softener, but many times more effective and longer lasting. Hey, it MADE for ropes.

b. Tubular webbing makes cheap, long-lasting, quiet, and non-water proof chafe gear. I've used this for 25 years. $0.68/foot. The small 1" webbing works for lines 7/16" and smaller.

Quick question are you running shock lines or just a single bow line

i'm just running single lines from aft and bow. I"ve tried spring lines which only helped marginally

Try an anchor or dock snubber to relieve some of the stress on the line at the hawser

Isn't it actually called a hawse hole? I thought the Hawse pipe was the opening for the anchor chain to go into the chain locker.

Actually a hawser is any fully enclosed place for a mooring line or anchor rode to pass thru the bullworks the hawse pipe is the pipe the anchor rode passes to the locker

I am about to experiment with a dyneema/dock line combo. Estarzinger gave me this idea from his snubber set up.
From cleat to about a foot outside hawsepipe dyneema, endura braid with eye, and cow hitch it to an eye of three strand, on the three strand I will have a bungee like snubber to absorb more shock loads. Make sense?

It's basically an anchor snubber set up, but tweaked for dock line. The dyneema has zero, well .06%, stretch so no creaking noises.

I haven done it yet, so many projects going on, but I will let you know how well it works for us.

As far as table in the main salon. We have the bulkhead model table and love it. We removed the starboard leaf and keep our engel fridge beneath. We can fold up the table to be completely out of the way. I did a little mod to accommodate a cross stitch my mother made me while she was sailing RTW:))). It can still be stowed with picture in place..here is a pic if I'm not making any sense.
Pic coming

Ocean Girl,
We had the same madly annoying problem until someone showed us a trick. We have standard docklines that we bought at West Marine, with chaff guards (white canvas type material that velcros over the line - also bought at West Marine). The trick is to take standard bar soap and rub it over the chaff guard or dockline where it rubs on the hawser. We have to re-apply every couple of months, but otherwise it completely silences the lines. Finally, peace and quiet. Now if I can only get my neighbor to tie off his slapping halyards...

Kieth,
We have the folding table and for the most part love the fact that it is out of the way most of the time and really opens up the boat. When down though, it is impossible to access anything under the port settee. Another thing to ponder - I wouldn't trust leaving it down while sailing for fear of damaging it if you are thrown against it. It isn't strong enough to withstand even a moderate lateral blow. So for passages, you have to work around eating and working without a table. I think the centerline table is better for working at sea. I'm not sure yet how I am going to deal with this admittedly small problem – although may become really annoying on a long passage. Everything is a trade-off, and nothing is ever easy when it comes to boats.

Hope that helps.

I've got the bulkhead mounted table and I LOVE it. I find it incredibly easy to stow, and so does my wife. I don't use the dowels, never a prob, but have been meaning to add some anyway and see. Mostly use it sans fold up leaf, unless the whole family is there, and then it is a great place for a family dinner!

It leaves a lot of open space in the cabin for stretching, or yoga. Also make port settee a very attractive place to hang out while being out of the way of traffic.

I am glad I opted for the folding table, and would do the same again, but it does make moving around the salon dangerous at times. I have more than once been thrown across the cabin. The interior does not seem small when you are falling from the starboard handrail to the port settee at high speed. Having the centerline table would sure make the trip forward safer in these conditions.

The room below would seem cavernous with the table mounted to the bulkhead. I could put up one of those mirror balls and have a dance floor.

Spoke to PSC regarding a quote to have one built. I know the quality would be second to none. Unfortunately it was priced way out of my league.

Spoke to an excellent marine finish carpenter. He came in with a quote considerably less however I don't believe it would be anywhere as nice.

Further discussiion and lots of sketches later I'm sure the price will rise.

Always tons of great advise here. I sure do like u guys !!!!!

After many years of living aboard our solution to dock line noise is a terry cloth wrap saturated with dish soap. We cut them about 8-10" long and about 6-8" wide (enough to go around the dock line at least twice). I keep an ondeck bottle of cheap soap handy if rain washes it away. We put this wrap over the woven style chafe guard already mentioned. When they are well saturated with soap, a squirt of water over each at night to soak the cloths is all it takes.

Also, we use large diameter nylon dock lines with rubber snubbers (3/4"d for springs, 1"d bow and stern lines). We've been in marinas with wicked surge and even though 1" lines may seem like overkill we've seen them stretch a snubber twice its length and are glad of its extra strength. Plus the larger lines work less and have greater bearing surface which also helps reduce the noise.

We also use similar anti-chafe and noise reduction methods for the 5/8"d nylon anchor bridle which goes in a Y from a devil's claw through both port and starboard hawseholes back to the midship cleats (we need the length for shock absorbing--no rubber snubbers on the bridle).

Just our dos pesos. Your mileage may vary.
