Slapping Of Water Under Stern

[Channel Sailor]

On my new sugar scoop style yacht I have when moored had my sleep in the aft cabin disturbed by water slapping under the stern when wind is aft. I vaguely recall that something like a hose or floats on a rope over the stern can stop the problem. Please has anyone else solved this problem already and how?

You mean one of these: http://www.cjmarine.co.uk/p/850/cj-marine-slap-stopper ?

or this: http://slapsilencer.com/default9009.html?P=technology ?

If you search the web, I think you'll find instructions somewhere for making one

Deffo cheaper - get a packet of health and safety earplugs. The ones you want are those that don't protrude the exterior of your ear so's you can sleep on your side.

P.S. I have to say that we solved it by not using the aft cabin! Our current boat does not have living accommodation in the stern, so the problem does not arise.

It does help, if you do not have the real thing, to tie your fenders end to end & string them round under the stern

1) Fenders tied together in a string pulled under stern. (Doesn't work too well when I try it)
2) Park dinghy against stern.
3) Park yacht bow to wind.
4) Arrive early so you're on the inside when rafting up.
5) Drink best part of a bottle of wine.

It is amazing how often the wind dies down at night and eliminates the problem for you.
Best thing I have found is to be prepared to turn her to wind or move to forepeak/saloon when it gets bad.

Nights on board should be spent in a drunken stupour of rum and whisky where nothing short of running aground will bother you.

Although some measures work, I don't think anyone has developed a definitive solution. Our boat is a 25 yr old design and we get the problem occasionally but it is not as bad as some later boats, such as a friend's Hanse 370, which is probably typical of boats of its generation. Perhaps the answer is to buy an old Hillyard.

My present boat is my first with an aft master cabin, and the first year I was quite bothered by the water slapping against the counter and it even interfered with my sleep.

By Year 2 or 3, I was already used to it and it stopped bothering me.

Now in Year 7 with this boat, I even kind of like it -- I associate it with the sun dappling the headliner reflected through the hull ports and the feeling of gentle rocking at anchor which I like so much.

So one solution, maybe not applicable to everyone, is just to live with it.

That is what I do on my boat with the various little noises that it creates in normal operation. I quite like the sound of whistling rigging, creaks and groans. However, my ear always picks up if there is a new sound that may spell trouble. It is a bit like listening to the constant hum of an engine and then a little rattle appears to prick your ears. I always feel sleepy on a boat due to the motion and rythmic noises

This is rare welcome advice from a medical man!

Anchor, then you'll be head to wind.

I had the problem in a marina on a finger pontoon where the wind came from behind, and twice at anchor because when the yacht came around with the tide the aft end was pointing into the wind. I like the dinghy idea, if the rubber dinghy is there in the water then I may as well swing it around and tie it across the quarter where the cabin is.

Thank you for the suggestions. Excellent forum this. The purpose built thing to guard against getting a slapping looks a little too pricey. The earplugs I will take on board, which I have used in the past when sleeping when at sea in fast yachts (when not skipper). Not using the aft cabin is a great idea except it was so loud one night that it kept the person the saloon awake! I will also try the dinghy across the stern which will do the trick in some situations.

 

[nigelmercier]

My marina berth is normally head to wind, but I can hear the tide coming in.

Perhaps the answer is to buy an old Hillyard.

Then the rolling at anchor might keep you awake - or send you to sleep.

It's a bad noise.

Worst in flat water when a motor boat goes past and sets a cascading slap the length of a marina isle. Berthing towards the root avoids the worst of it.
