Noise driving us barmy! Any suggestions please?

[whiskeypapa]

We have a new boat with generator fitted centre aft. We think the weight is lowering the bathing platform which causes water to continually slam on the aft of the boat when we are moored aft to on our mooring. Could we counterbalance this with extra chain in the anchor locker to lower the bow? Any suggestions would be welcome please.

Why not try running lighter with reduced water and fuel (if the tanks are aft). It will make the boat lighter anyway, give slightly better fuel economy, and trim by the bows.

You can always top up with fuel if you need to before a long passage and, unless you are going to be anchoring off there is usually water available locally when needed.

Just a suggestion.

Not sure this would work in the situation you describe, but I seem to recall a forumite solving the problem of water slamming on the stern by getting one or more of the foam sausages that are often used to help kids learn to swim (not sure if I'm describing this very well) to attach to the boat at the waterline. The sausage absorbed the wavelets and stopped the slamming.

I think you'd need to take all the engines out, to make any sort of difference.

Didn't someone make up something similar using standard (cheap) pipe insulation?

Could well be - it's basically the same principle, and probably cheaper materials!

when we are moored aft to on our mooring

Don't know what boat you've got but I don't think it'll be the generator causing the bathing platform to hit the water. A typical 4Kva gennie weighs about 100kg which is only equivalent to about 100 litres of fuel or water (OK not exactly same) or put it another way, 1 fat bloke standing in the cockpit. Not enough to sink the boat at the stern IMHO. I don't think adding anchor chain will make much difference apart from reducing the speed of the boat by a small amount
Apart from the engines, the largest weights on board will be fuel and water so you could try mooring with low fuel and water to see whether it makes a difference but I guess you'll just have to live with the noise

Try mooring stern in. Don't think a weight shift will help.

Oi!! 100kg, that's my weight fully clothed, and I'm not fat, just heavily built. Cheek.....!

Thank you all - will try some of your suggestions

I love that response - so you! But so true.

Purely as a test to see just how much wt you would need on the bow - get a water butt and sit it right in the bow to the rail and fill it up and test at each 5ltrs. You will soon know just how much wt you need to counter the tilt and hopefully the noise - might only be 25kgs - which you could do via anchor chain perhaps.... just a thought

ear plugs will do it and they have the added bonus that you wont hear the missus complaining

 

[JohnRob]

Are you on an exposed mooring? Most boats with a bathing platform where the hull does not extend under neath it to the edge of the platform will suffer this to some extent or another - but it is usually if the tide causes the stern to face the incoming waves. Pretty extreme if it is happening in a sheltered marina mooring.

Mind you, makes a change from the "glop glop glop" from the chines if moored t'other way round and you are in a bow cabin....

What is your boat?

 

[whiskeypapa]

It,s a Sealine F 37

You are quite right SHE IS a Sealine F 37 but unfortunately your tide tables are of little use as SHE is not in the UK
