DO YOU HAVE A SLAPPER ?

[RIMCOas01]

I have just spent 2 overnighters aboard a Nimbus 30S Nova ... the noisest bl...dy hull I have ever been on (is it the air stepped design I wonder ?)

It was not just the slapping, but the intermitent gurgling .... !

I cannot recollect reading anything about this ... ever ! I know boat hulls are designed for efficiency when underway, but what about when idle. Reading thru various mags and boat tests I do not see anything about boats being reviewed for overnight suitability (excl. space & equipment).

Are there some hull designs that we should stay away from if one intends to sleep (live) aboard ?

Had the same problem in a bilge keel Westerly Konsort which we hired from Hull 10 years ago. I did not have any problem with my Macwester 30 (bilge keel) so I guess it is down to the design.

I've seen boats put down an inflatable skirt around the stern to reduce this. Must be desparate for a bit of quiet.

I'm totally with you on this one. Having owned a centre cockpit boat with an aft cabin, I was constantly kept awake by slapping. I did buy a wave muffler which helped and also used ear plugs, but the wave muffler was a bit of a hassle to setup and I just don't sleep well with earplugs.

When I came to chose the new boat, it had to have a cabin that didn't suffer from waveslap, or I wasn't getting it.

For sailing boats it is the stern that is the problem area, whereas I understand with Mobo's it's the bow that is a problem. So the rule is forecabin for raggies and aft cabin for stinkies.
