I'm a new liveaboard, and I expected certain sounds and a level of continuous movement. (I was on a 550 foot long cruiser in the navy, so I am not totally new to this.)

But the last few nights I've heard two noises that I didn't hear the first few, possibly because I got in so late those nights and was so exhausted.

The first is a rapid but short lived pounding sound upon the hull that sounds like high speed screws. (No, I don't think I'm being torpedoed.) My slip is 200 yards from the mouth of the marina, and the main channel is twice, possibly three times that far from the marina. Am I hearing -- and feeling -- the vibration of the screws of big fishing boats? And if I am, what are my chances of getting them to not sail past me when I am sleeping?? (Yea, yea ... that's like asking "Will my boat appreciate in value?")

The second is is the area of the mast and only audible when I am in the cabin. I thought it was wires and lines slapping the mast, but I have secured those away and the sound continues. In sailing movies -- "Master and Commander" for one, or "Bounty" -- you always hear the creaking of the boat. It almost sounds like that, but more metallic, and just above my head when I am in the "head".

Thanks,

There are a couple of anchorages here in the San Juans that seem to collect the propulsion sounds from nearby traffic lanes. First time I heard it, I spent 15 minutes pulling up floorboards in the boat to try and locate the source of the noise. I thought it was a hidden bilge pump at first.

Can't comment on the first while in a dock, but I have experienced this at anchor from vessels far away. Water transmits sounds is strange ways.

For the second, many masts have electric wires in them which may not be attached to the inside. So any movement of the vessel will cause those wires to strike the inside of the mast. You clearly won't hear that underway given other background noise. But when docked, noise such as this will become noticable.

Remember water carries sounds a LOT further than air does...

What kind of ships were you on in the Navy? (Curious)

Wires and halyards inside the mast still move with the rocking of the boat.
The only way to stop it is to encase the wires and halyards in something.
I read an article where one guy stuffed swim noodles into his mast to 'lock' stuff up, I don't recommend it.

You telling me that time on the cruiser didn't teach you to ignore noise and sleep when it was time to sleep? (Retired Navy)

If you're certain the first noise isn't coming from within you own hull, then my guess is that you are hearing a neighbors electric water or head pump. Electric heads are very noisy, and in my experience seem even louder outside of the boat they're installed in than inside.

We have some major ferry terminals here.. and the noise that transmits into the boat from a ferry running hard against its ramp while unloading can be impressive..

Quite possible you're hearing traffic....

Mast noise could come from the gooseneck or the vang. Usually they make creeking/squeeking noises. Try a drop or two of oil. If it sounds like wires banking on the mast, it may be coming from inside the mast.

Another option- learn to enjoy the noise (as long as your neighbors aren't complaining).

You'll get used to it...

On offshore deliveries, I'm always amazed at how well I sleep once past the first few (loud) days at sea. Like a baby; maybe even more soundly. BTW, the best way to gently but successfully wake someone up for their watch is to gently pull on their pillow.

On land, I'm always surprised, in the spring when we start sleeping with the windows open after having them closed all winter, at how loud our neighborhood is -- trucks emptying dumpsters, cars on the cobblestone street, train horns at grade-level crossings, tugboats at the lock down the river, the neighbor's squeaky garage door. Then we're used to it and sleep right through it after about 3-4 days.

RUN!!!!! RUN!!!

WARNING!!!!!!!!!

YOU ARE IN GREAT DANGER!!!

MOVE OUT NOW!!!

YOU'RE INFESTED BY THE DANGEROUS:

MORPIONS!!!

Leave the boat and your belongings back....those little creatures, or animals you are getting are not weed eating fish....they are called "MORPIONS", they are like the crabs...of crabs...they are experts in osmosis, and enter the hull thru blisters....they squeeze themselves thru the molecules of fiber glass and wood (luckily not thru Carbon Fiber and Kevlar, as they avoid those boats..they're allergic to fast boats), on most boats, specially crappy old ones and Catalinas...

Here's a mug shot of one done by our resident artist..



What they do is, as they pass thru the hull, they get together, they aglomerate into larger masses, they eat cookies and chocolate, and then...they rape sleeping sailors...but they leave no traces...other than a funny feeling when you next go in the head....kinda like "ants in the sugar box", if you know what I mean....:D :D :D An itchy a**hole.....:D :D

You need to paint your hull with a super rare very expensive paint called:

"LA SURRENDER"...

Unfortunately its very very very very EXPENSIVE...as it is made with a very rare substance, called French Bravery....so only a few cans were made...

what you do...if your lucky to get one can, is paint it over your antifouling...

I have never seen the MORPIONS, I know they exist, because some guys around my marina walk "funny"..they suffer of Gayness...a disease spread by excessive admission of Morpions analy...known victims: Boy George, Elton John, Camaraderie...etc..sad but true...

Most people..... don't admit having those bore making animals in their boats..... some do admit....but they're "openly" "different"....

I'm protected... my cruising speed is over 6kts, and my boat moves..hence no marine growth

I'm pretty new to living aboard , but from day one I've loved the noises onboard at night . My favorite is a dull clunking from 2 cast iron pots clunking together gently in the galley . I love all the creaking & groaning in the boat at night . I've associate those noises with my well being & am comforted by them . The nights I've had trouble sleeping are the ones where everything is dead still .

From another liveaboard- the only sounds that bug me enough to get up off my lazy *** is a halyard banging. I do love the motion and sounds living on the water and have a hard time sleeping on land:) My slip is very near the Oakland airport and sometimes they fly so close it makes the mast buzz which gets my dog barking which makes something spill which makes me cuss which makes dog go hide;) Oh and by-the-way beer works great as a sleep aid.

The loud chewing noise you are hearing, are caused by Mutant Marine Boring worms that have a strong taste for Fiberglass. :rolleyes:
But those of you trying to sleep in San Diego Bay. The pistol shrimp are night time creatures and are snapping away and it sounds like that you are at the wrong end of a rifle range. :D

When I've overnighted on my boat in the marina I will often here (more in the warmer weather) lots of little "popping noise" like someone popping the cells in bubble wrap. Some sort of water creature living attached to the wooden jetty no doubt.
Most annoying noise is the sound carrying across from other liveaboards on their boats.
