V-berth noise

What is it exactly about the SR hull that causes this wave slapping noise?

I'm probably going to get the actual word for it wrong. I'm thinking they're called strakes...but on my boat on each side of the bow there is a strip of the hull that is completely horizontal (parallel with the water surface).

This (strake?) lifts the boat out of the water as you move forward...allowing it to plane quickly - but its also the area that slaps the water as the bow bobs up and down and/or the waves impact the front of the boat while stationary.

If a guy could figure out how to temporarily attach some of those earlier-mentioned foam tubes (or even some flat foam strips) to these flat areas..you could probably disrupt the water clapping up against this area...it'd look kinda funny - but I think it would work. On my 420 - probably only need about 8' on each side...just where the waterline makes contact with the horizontal surface.

MAYBE...some flat foam strips with double sided tape...though any tape that would be good enough to stick on a wet surface would probably be a nightmare getting back off.
 
That is exactly the area I am talking about. It can be almost smooth and every little rock of the boat from the wiind makes the noise. It can be really bad when the waves kick up. The VIP suite is an option when we don't have guests, but the admiral needs the master bath for makeup, hair dryer, curling iron. I guess the next step is the 580DB with the mid cabin master...
 
Briamanst, I know what you mean on the wave lapping and I agree with many of the other guys that 3 drinks should cure that. I keep thinking how my wife likes the 55DA (or an older model 54DA) with the stateroom aft. We were looking at a 54 and she really liked the larger master aft, no more climbing up to get into bed. Oh well, next boat! Sea Gull hit it right, just buy a new 58SB and think how well you would sleep- I know I'd be up all night worring about how to pay for it!
 
This is not a SR only issue. All boats experience it to some extent. Many sailboats have the same issue - only at the transom instead of at the bow.

I remember from my sailing days that there was a company that made a device to wrap around the stern of a sailboat (or the bow of a powerboat). The device was basically an insulated curtain (maybe 12" top to bottom and 6-8' long) that had floatation at the top and weights at the bottom. There were lines attached at least at each corner. The idea was to float this thing a few inches away from the boat with the idea that it would break the wavelets and provide an area of still water against the hull. Not sure if it worked, but it's cheaper than buying a 58DB.

That noise is what puts me to sleep. That and a movie. We never seem to make it all the way thru a movie before dozing off. Especially if I'm forced to watch a chick movie.

I’m with you.

I look forward to this sound all winter.

It’s been about ½ year and we are close to launch. I’m full of anticipation.

Just a tip about having to endure the chick movie. Have the TV so you can view it in bed. Put in ear plugs so you don’t have to listen to the chick movie or put a pillow over each ear. Have your wife give you a message as she watches the movie. One of two things will happen.

Either you will fall fast asleep or (insert 70’s twangy porn music here)

The noise is from air being trapped up under the hull creating the "Slap" noise. There is no mechanical cure for this that can be undertaken from inside the boat. Floating collars and barriers may work, but they are tough to carry along on cruises. So if you just can't learn to sleep through it try these solutions.

Fix # 1 Knock back a stiff drink and cuddle up to the Admiral and maybe you'll be able to lsiten to different noises.

Fix # 2 If on the hook and the winds and currents co operate lead your anchor line aft to a stern cleat and lay off stern to the wind. This will quiet things down, But I wouldn't do in more than 5 to7 knots of wind on my boat.

Fix # 3 If in a slip, spin the boat around bow in for the evening, but in heavier winds the sea walls will make more noise so belay this idea at the slip in high winds.

Fix # 4 If tied along side a dock, spin your boat around so the master is away from the wind.

Fix # 5 Put on a few CD's with the music low and give yourself something else to listen to until you drift off, put on Barry White and you'll never get to sleep:smt038.

So Chad you would not buy a Tiara to solve this problem :huh:
 
I never had this problem, I simply dont hear it...oh wait, im deaf.

I'm with you! All this traffic on the scientific level about sound dampening and harmonics makes my head hurt. And I will be listening to that sweet sound this weekend. we are expectiong 80 degrees in the Sacramento area Fri-Sun. :smt038
 
Ok...this is not good news. I just bought my first cruiser, with wonderful thoughts of the family out camping on the water in some distant beautiful port. Instead, I am struck by the brutal reality, of a wife who barely sleeps anyway, who will bolt to the nearest Hilton at the first waves banging the hull. Well...it sounded like a good idea. :smt101
 
Doug... Does she drink wine?

My admiral is the same way... on land... on the water we both tend to sleep deep and long. I usually wake up at the crack of dawn, but on the boat both the admiral and I sleep late every time.

Don't give up yet...

Yeah I'd say you're not in trouble yet. A lot of it has to do with your timing...especially early on. Pick some calm days/nights to get started and go from there. You'll find that after a good day of boating and lounging in the sun (on one of the 6 days that you guys actually get sun)...you'll be ready for solid sleep.

Nothing better than that first calm, quiet morning on the hook in a calm anchorage...what a great feeling.
 
The dreaded "wave slap". Unfortunately, buying a Tiara won't remedy the situation at least as far as my model is concerned. An earlier poster suggested the lifting strakes were responsible. I have a tendency to agree.

Is anyone else annoyed with the noise of waves lapping against the v-berth? If so, has anybody solved the problem. Even the smallest waves seem to make a lot of noise. It is worse at the marina where the wind shifts around the boat. I have been trying to think of all kinds of methods including floating swimming noodles around the v-berth to try to break the wave before it hits the hull. I don't remember it being this bad on my old 340. I am just looking to see if anyone else has experienced and/or solved this. Thanks.

I call this "slappy hull and his friends" and hate it. The owners of the Cruisers Yachts 3370 next to us swear it's quieter in the aft cabin.

+1

At home on the weekends we are up at 7, on the boat, up at 9...sleep like logs in "the cave".
 
To get rid of the noise, buy a 120 Feadship! and then sleep in the hotel next to the anchorage!
 
Too funny! She does drink wine (makes a note...double the on boat supply)...and lots of it. We'll see how it goes, I won't give up. A day on the boat does wear you out, so I suspect we'll be like cave-couple (a few posts up) :)

But the bright side is...if it doesn't work out...it's a heck of a weekend bachelor pad with a great view, and yes, on those 6 days it doesn't rain here.

Hilarious!
 
The wave noise on our boat is loud at times. I think I'm going to experiment with the noodles.

Of course the noise from our hull is nothing, though, compared to the folding trimaran three slips over. Everyone on the dock complains about that guy. He has 3 hulls, two of them folded up on either side of the main hull, and those 3 hulls like to slap each other big time.
