@ Fast Fred - I agree that engine noise transmission is mechanical as well as airborne. Is the Seatorque BOSS system the solution? I am hoping it might be. Tony Fleming was using them at one time - I don't know whether he still fits them or not.

@jmiele - Thanks for your very helpful reply. If it wasn't for the fact that I expect to spend time in the engine room under way I wouldn't bother with a sound enclosure for the engine for exactly the reasons you (and some of the other replies) have given. If the engine room is an uninhabited...

Just how much time do you plan to spend in the engine room with the engines running Depends on the length of the passage. Lymington to Bembridge = nil time in engine room (I hope). Azores to Bermuda - who knows? Depends what breaks. In there will be all the pumps, most of the Maretron sensors...

@WestVanHan Phew! I often think with my wacky ideas that I am the only one thinking outside (in this case inside) the box. So it's great to find someone else thinking the same way. How quiet is it in your engine room/compartment when the mains are running? Could you work in there if you had to?

With an engine on classic engine mounts, taking tons of thrust it is simply impossible to reach that level of soundproofing. OK, but..... I think you'll find that a lot of the big boats with big power being built these days have soft mounts and flexible couplings with thrust bearings. Very...

@CDK - thanks for your reply. OK, I get why it isn't done. But I have a reason why I would like to cut the sound down in the engine room: almost every pump and other mechanical device, and the workbench, is going to be in there so I'm going to have to work there sometimes when the main is...

@rasorinc Thanks for your reply but the genset manufacturers don't have any trouble doing it so it can't be too difficult. They have the same angles and projections to deal with - they just make a sound insulating box and cover the genset with it. Also the amount needed to insulate an entire...

Most generators on modern powerboats are installed inside sound enclosures - example: Northern Lights But I haven't seen a single example of a propulsion engine enclosed to reduce noise, even on the latest designs and even when there is plenty of room for a sound enclosure - example: FPB...
