V-berth noise

I am with you guys on the hull slapping. It keeps me awake at night when I am on the anchor and sleeping in the V-bert. It feels like the boat is taking off on it's own.
The 540 and 580 solve this problem by having a mid cabin master. (something to consider when choosing a boat)
My 500 also had a second noise problem. The generator (all they way in the lazarrette and in a sound shield) is silent every where in the boat except in the V-berth where you are trying to sleep. It resonates in that cabin so bad it feels like you are trying to sleep in the bilge with the engines running. I even took that gen set and mounted it up on a seperately rubber mounted platform and it only made a modest improvement.

I just took the 500 back in trade for my 580 so I will be following this thread with interest and I will probably try a few things myself and report back.
 
Like presentation I look forward to this all winter.. I'm on a comercial traffic water way and the barge traffic picks up considerably at night. lots of ups and downs, lots of slapping... oh wait, that's just my wife and....oh never mind:grin:. Sell your boats and buy an RV, no waves involved:lol:
 
Good gosh... what a BUNCH OF WHINERS!

"My yacht has waves slapping the hull and it keeps me awake at night."

Obama will fix it for you...

Besides, I'm not sure how you can hear the waves over the loud AC compresser and water discharge mounted under the bed... Sure wish I had a Tiara.

In a couple of month's, we can cash our "stimulus" check, wad up a $100 bill and stuff one in each ear....that should dampen the noise...:lol::lol::lol:
 
Most of the time we don't have a problem with the sound of the wave slapping the bow. When it is too loud we sleep in the aft bed, where it is quiet.
 
Whining or not, this is a valid thread. I do sleep with ear plugs in. I have ever since my wife and daughters turned my bathroom in a salon every morning---regardless of my schedule (working nights...). I was home sick yesterday, but had to come to work (on base) early to see the doc, then had obligations later in the afternoon, so I slept on the boat. Winds were from the worst direction (only bad direction) in our marina and the slapping noise was loud until the earplugs expanded out real well and sealed all of the gaps. Then, the rocking was really comforting, and the slapping was inaudible.

That being said, I can still hear things that are out of the norm. If I leave my phone on, the ring wakes me up. Someone climbing on the boat wakes me up - the rocking associated with the deep sounds of foot steps. High pitched sounds wake me up. The slapping noise becomes a non event.
 
Gary Im with you, If you don't like the water, Get the hell off the water. Go be a land Lover, Buy a camper, then you won't sleep at night from that the hollaring and noise making goes on in the state park....better yet buy my fifth wheel trailer, ......Or quit whinning......Or just keep being a baby......wa wa wa.

Guys. I disagree vehemently with this attitude. If this thread bothers you, move on. If this noise is a problem for you, read some great ideas as to how to dampen its effect. That's what the forum is for. It's not for telling people their concerns are invalid as decided by you and they should, therefore, stop boating. Give me a break. Give your fellow boaters a break.

Sure, some posts on here seem trivial, but I assure you, to some, they are not. There are those that yell at people for putting tv's, let alone theaters, on their boats. They don't understand it. That's fine, they should ignore it and move on. Others don't agree wtih installing underwater lights, others scoff ice discussions because they live in Florida.

There are no wrong discussions, except maybe political and/or religious, and even they may have their proper place due to the potential impact on boating.

Bottom line: I would encourage each of us to be tolerant of other's needs and posts (exept the ones that criticize other's concerns).
 
Tolerance is one thing, 6 pages of supposedly grown men carrying on about how their sleep is interrupted by water touching the sides of their half million dollar boats while their boats are sitting in the ...............water, well that borders on embarrassing. Perhaps a pacifier might work? Maybe hang one of those mobiles up above the v-berth....

Perhaps this thread would be shorter if not interrupted with off-topic posts. If these men were hanging out in soup lines looking for sympathy, I would agree. If these men were logging into a Sea Ray boat owner's forum seeking advice from other owners, I would consider it a reasonable act no matter how long the thread.

Was the Gen mounted on the stringers? This would be like cups and string with the vibration of the gen traveling all of the way up the boat and everything mounted to them would vibrate. If they happen to come into contact with plywood or fiberglass, you have the makings of a crude speaker. If these also happen to resonate at the frequency of the gen, then you have an amplified speaker. Each room will also have it's own resonating frequency. as you can see, it gets very complicated real quick on dealing with the issues.

a rubber platform, like you've experienced, will help very little. you either need to move the genny or isolate it (as best you can) from the structure. there are springs, isolation pucks etc... but these are designed for installations that aren't rocking and rolling. you can't have the genny flying off the mounts when you hit a wake, so I'm not sure how well they would work if you can't move the genny.

I'm trying right now to isolate my fridge from the cabinet, everytime it cycles on, it resonated in the cabinet. It's actually very quiet, but the little vibration it produces is amplified by the lightweight material it's mounted on and resonates in the cavity it's in.

In my boat, if you lift up the engine hatch, you can see they know what is effective in reducing the sound. Foam with a heavy vinyl barrier, it just weighs a ton.

Um...I see you have a 320. I had a 340 two years ago and the v-berth noise was relatively insignificant. However, with my 420DA the noise is significant. So much so that in certain anchorages and weather it makes sleep extremely difficult in the v-berth (and I'm a heavy sleeper). Maybe because you have a 340 you are not aware of how noisy this can be. I got a look at the strakes on my hull yesterday and they are nearly 6 inches wide at the waterline. That's like a 12" wide piece of plywood slapping the water all night long right next to your head --- sound good to you?

To suggest that somebody should plunk down $400,000 to $600,000 and maybe more - then put up with noise that makes sleeping difficult seems pretty dismissive and certainly not very much help to those of us who have this issue. That's kinda like saying the furnace in your new house is so noisy you can't sleep - but don't try to figure out how to fix it because you could be living next to the train in Chicago. :huh:

Once again a smaller boat owner downplaying an issue that likely doesn't even affect him. Why do you come on this forum and criticize owners who have paid a hell of a lot of money for their boats and are trying to improve their situation. Have you ever heard the boat slap on a 42DA? Apparently not...but maybe you'd also like to give us hell for posting questions on changing Racors or using additives in our Diesel fuel...or a few other things that don't apply to a 240...

What borders on embarrassing is you criticizing a post which you apparently know nothing about (ie: "water touching the sides")...thereby stifling potential posts which might help us all out.

Shawn, firstly, you're wrong, it does affect me. I'm just not crying about it. Secondly, I'm not criticising a post, i'm criticising the entire thread. My opinion is that it's assinine and makes the "big boat" owners participating in it look foolish. The issue of water noise on the hull has NOTHING to do with the size of the boat. The same water noise occurs on my lowly 240 as it did with my equally lowly 300.

I never said your boat was lowly. If you don't want to feel like you're being talked down to - don't post in the "Sport Yachts/Yachts" forum.

But I surely disagree that the size of the boat has NOTHING to do with the noise generated. I would suggest - that the strakes on your boat are considerably smaller and therefore resonate (or create) considerably less noise. Take a 3" wide piece of wood and slap the water...now take a 12" wide piece of wood and slap the water...same noise - probably not. Again...have you ever slept aboard a 420 during wavy conditions? Like I said above...I operated a 340 all summer long two years ago and never experienced the noise that I do with the 420. Gee maybe we just went all that summer on Lake Erie without waves :smt009

Another thing to consider is how many nights per year a 240 owner spends on board vs. the 40+ guys. I bought my boat with the expectation that we'd be spending ~75 nights per year on it. Is it ok also to expect that 30% of those will be with that much sound going on all night long?

Finally - consider how much money is invested. One would assume that $400,000 would deliver a relatively pleasant sleeping atmosphere...which in fact it doesn't always. Are we talking being on the hook in 5 footers? Not really...sometimes a lowly chop can really get the sound up down there.

Don't get me wrong - I'm not saying the 420 is a bad design - its probably the best all around boat I'll ever own. But it does have a tendency to make a lot of noise up in the v-berth in mildly wavy conditions. Apparently its asinine to think that it wouldn't...or to even discuss a remedy to the situation????. :smt018 With your reasoning - I suppose we "big boat guys" should be embarrassed to discuss the issues with the reduced lubricity of ULSD...because thats just what us "fools" have to put up with when have diesel engines....:huh:

I don't know, but I definitely did not notice the slaping in our 400DA as much as the 510DA.
Maybe there is something about the boats size. Is there someone here who can apply some science to this and take the emotion out of it? Frank where are you?
