Hull Slap at Anchor

[henryv]

I must confess that too many sleepless nights was one of the reasons I sold my monohull and moved to a cat - the deeper hull shapes and raised berths makes for quiet sleeping.
When I still had my Beneteau I had some luck with tying a few pool noodles under the stern but these only worked when waves were very small. I also considered a product from SlapSilencer eliminates excessive wave slapping noise in aft cabin sailboats | From Anson Sailmakers NH but sold the boat before trying it.

Fill all your jerry jugs with water and put them on your swimstep-aft. If it does't do anything, add more till it does.

My triton slaps fairly loudly... not terrible unless you get stuck under the cockpit...

I'm wondering, since the noise is being transfered through the fiberglass... and not from the outside and down the hatch (At least on my boat) if this isn't a place where energy absorbing mat could come in handy? On cars there are various audiophile grade insulators that take sound energy and turn them into heat, instead of just adding mass to the panel. In addition to mat, there are spray on rubber mastic products with ceramic balls that dampen sound with very little weight.

Do cored hulls have similar noise issues, or are they quieter than solid laminate? Steel boats supposedly have less noise from the many inches of spray foam.

Check out this link,I know it is at a UK chandlers but the product an inflatible buffer which ties underneath the transom is probably available worldwide.

Sorry, my mistake it may not be inflatible but it should still help cure hull slap.
