DeanS Posted August 28, 2013 Report Share Posted August 28, 2013 (edited) gday:) Can I install a new siren at the stern rather than at the bow? It would mean no need to run an extra 12metres of cable. It would mean less risk of voltage drop. It would be simpler to install. I know having a siren at the bow is commonplace, but I have seen some that arent. Surely a siren would be almost as loud at the stern as the bow......a slight decrease, but still audible?

by'eck Posted August 28, 2013 Report Share Posted August 28, 2013 I think you have answered all the questions yourself Dean. If you have a bowthruster with adjacent batteries it can take power from them via relay operated from the stern. Same for tunnel lamp. Link to comment Share on other sites More sharing options...
Nickhlx Posted August 28, 2013 Report Share Posted August 28, 2013 I guess it depends how loud it is and how long your boat is .... Personally I would always fit at the front as it would need to be very loud at the stern ( uncomfortable for you) for the oncoming boat's helmsman to hear it over his engine, and every little helps.. Cable isn't that expensive... Nick Link to comment Share on other sites More sharing options...

Some older ex-working boats have hand operated 'klaxon's mounted atop the rear cabin so I see no reason why not... Link to comment Share on other sites More sharing options...
Robbo Posted August 28, 2013 Report Share Posted August 28, 2013 I've seen plenty of boats with a horn at the rear. Do you have a bow thruster, you could use those batteries and a relay with a thin cable going to the switch. Link to comment Share on other sites More sharing options...
Québec Posted August 28, 2013 Report Share Posted August 28, 2013 Recently saw a wonderful,hand-operated brass klaxon at the stern of a nb. Evoked feelings of extreme envy! Now on the hunt for one. Link to comment Share on other sites More sharing options...
bizzard Posted August 28, 2013 Report Share Posted August 28, 2013 I think I'd position the siren, especially if topless, draped across the bows like a figurehead. 1 Link to comment Share on other sites More sharing options...

Athy Posted August 28, 2013 Report Share Posted August 28, 2013 Damned Bizzard, bear me to it! I was going to say that if a siren came on to my boat she could position herself where she pleased. Until Mrs. Athy spotted her, at any rate. Dean, I think what you refer to as the "siren" is generally known as the "horn"....though that could lead to merry quips, too. But to be serious, if I may, I have seen numerous boats with their horn towards the stern. It seems especially prevalent amongst those who have the two-tone air-horn jobs. The horn on ours is beside the slide, and it's not a very loud one. However, as I am always on the boat when it sounds, I couldn't tell you if the sound travels far or not.

Ok a horny siren then, Oh norty me. On second thoughts I think Hooter sounds nicer. Link to comment Share on other sites More sharing options...

Gingerbeer Posted August 28, 2013 Report Share Posted August 28, 2013 (edited) I think I'd position the siren, especially if topless, draped across the bows like a figurehead. That would certainly alert an oncoming boat and stop it in its tracks...as long as a man was at the helm.

mark99 Posted August 28, 2013 Report Share Posted August 28, 2013 I've had a 2 of people moan at me on blind bends "did you not hear my horn" Well no you tit, your horn is too quiet and situated next to your stern and I've got a non silent engine.

Nickhlx Posted August 28, 2013 Report Share Posted August 28, 2013 Errr ... my point exactly - a horn is to make people aware when necessary, not a bit of "bling"... That means as loud as reasonable and as close to where it's needed as possible ( i.e. the front) Some people can't even hear those on the towpath next to them over the noise of their engine - I couldn't ( semi-trad, Beta 43 with hospital silencer) until I soundproofed the engine compartment, and it's still difficult to hear those 60 feet in front of me...

Hawkmoth Posted August 28, 2013 Report Share Posted August 28, 2013 Some older ex-working boats have hand operated 'klaxon's mounted atop the rear cabin so I see no reason why not... Met one at a blind corner once. I hooted, didn't hear anything so carried on. Met the guy in an awkward place. He said he replied to my toot, but then hit his horn again and it became clear why I didn't hear it, it was pathetic. Link to comment Share on other sites More sharing options...
ditchcrawler Posted August 28, 2013 Report Share Posted August 28, 2013 Put it where you like is the answer. 95% can't be heard by other boaters over the sound of their engine. There was a nice looking solid (heavy) 12 volt brass one for sale in Ely Antique center for £200 Nice and shiny Link to comment Share on other sites More sharing options...
Nickhlx Posted August 28, 2013 Report Share Posted August 28, 2013 LOL ! .... rising to 99.5% if you put it near the stern of the boat Nick Link to comment Share on other sites More sharing options...
