Sound Signalling Device for a RIB

[GaryC]

My understanding is that a RIB should carry a horn as a sound signalling device. Some come with an air can and some don't. [The air canister type seem to be prone to misuse on a jointly owned RIB]

I have been asked whether a simple whistle (plastic) will do. My feeling is that it won't but Annex III of the COLREGS where the sound device has it's specification, could indeed be a violin. I presume like the rest of the COLREGS, there is an interpretation somewhere.

Is there anything to say that a whislte is not up to the mark?

What do others use? (and where do you get them from?)

Many Thanks

A chandlers should be able to sell you one that you just blow into - they are plastic, so unlike the gas ones they don't run out of air or rust - perfect!

What Cookie said.

They're good enough to satisfy the coding regs on a small boat, provided it can make an efficient sound signal.

i dont think that in reality whistles of the lifejacket type dont travel the distance as a horn will ,though perhaps the ones with the pea in may be better ,
i have seen some really small ones that you blow which give out a really deep tone like a ship which seem ok ,
if you carry foot pump/bellows for topping up the tubes make an adapter to fit the end ,,saves getting a red face if having to use it for long periods ,

,i know one yachtie from our club that fitted a car tyre valve in the bottom of an empty fog horn canister ,,disposable type,, and he can top that up with his car foot pump if in prolonged periods of fog or sea fret,

i remember looking an angling boat which we were doing a brief equipment check on,,day launcher using our slip ,, and they had a toy plastic trumpet ,worked ok ,,,,though think it would have done me head in on that boat listening to that squark for a couple of hours in the fog ,,lol

I figure if I am ever broken down over a prolonged period, that The Missus will be shrieking at me in such a way that a horn, whistle, or a violin would be completely unnecessary...

We have the electric horn, and each PFD has a whistle attached. Can you get Fox40s over there? They're incredibly loud... and designed and sold by a client of mine~

I've got one of these-It's called an Attwood Bellow:-

Fantastic bit of kit-louder than all the ones you can buy that blow yourself in the UK. It wasn't much more to buy and ship from the US than a disposable aerosol horn and it's rebuildable.
It delivers a continuous tone too, rather than sounding like a duck call.
It works even after being submerged, though you do have to give it a shake to get the water out.

I realize that your UK regs may be different, but here in the US, a whistle is considered a legal signalling device. Actually, so is a cooking pot and a spoon to pound on it with. Basically anything that makes noise.

The problem I've seen with the can-powered horns is that invariable they get wet and rust and release the gas before the thing is needed. The problem with whistles (aside from the monster thing that Nos posted) is that they tend to migrate to places where they can't be found.

I've got an electric horn (an Ongaro all-stainless job) mounted on top of the A-Frame, augmented by a small can type in the console as a backup, and usually several whistles scattered about in various boxes on the boat (that usually end up in other divers' BC pockets.)

'snot a monster-it's smaller than carrying an aerosol horn.Works on a vibrating diaphragm.
Sounds like a fog horn too
