Bluetooth jargon aside, I've been struggling to work out what 'combing' was; seriously thought it must be some sort of hi-fi term, then realised - I think - it's the cockpit coaming ?!

Maybe a recognised spelling I've simply not come across before...:)

I wish!!! The LOA is 11.1 meters and the stereo in the saloon is let's say in the middle of the boat (actually it's less from the cockpit).
Anyway, I wish had this problem in a 25+ meters super yacht......I believe I could live without the speakers!

My point was range AND line of sight. I dont think it will transmit from the saloon to the cockpit if there is anything solid in the way (including you). It isnt like Wifi.

Apologies, It was a particularly bad day. It is indeed coaming. :)

Oh come on. Sharing a bottle of Jack Daniels with mates in the cockpit after a good night out, playing old Motörhead tracks on a really good stereo. It's what anchoring is all about.
Mine's a Highland Park :D, ahh your the Motörhead fan :rolleyes: I'm more a 'The Corries' or 'Dick Gaughan' fan myself.

Not quite - it will depend on the device though ...

my iPhone will transmit and the speaker receive through both an internal wall and external wall ... I can even get in the way and it'll carry on - although there are a couple of dropouts ...

Given that I'm transmitting through brickwork (internal wall is structural & brick!) I wouldn't think that an iPod down below would have much of an issue transmitting to a wireless speaker on deck.

It is indeed just like WiFi!

In fact it's a bit more robust in a like for like situation. Both Bluetooth and WiFi use the 2.45GHz band. WiFi occupies fixed channels which are nominally 20MHz wide whereas Bluetooth hops rapidly over the full 80MHz of the band, occupying 1MHz instantaneously. Thus in fact Bluetooth is more robust in industrial situations.

The difference however is that people making WiFi access points bother using muliple antennas and good ones at that, whereas people making Bluetooth phones do a lousy job with the antennas because typically it only has to go round a human (some with larger circumference than others!). But the same carrier frequency is used, with the same propagation characteristics, and you certainly wont have a problem going from cabin to cockpit unless you've a superyacht or a cr**p& implementation.

Another way of looking at it is WiFi outputs +15dBm typically, and has a sensitivity of about -80dBm (depends on nominal rate, assuming 802.11g), so is only a little better on loss budget, not so much as to count if you have equal antennas.
