Navigation Lights
« on: 14 Jan 2016, 18:43 »
Swallow Yachts have 'em built in, along with the slide-away kitchen sink and all the other mod cons, of course but is there anyone out there with a "proper" Swallow Boat (Ho, Ho!) who has found an answer to the emergency Nav Light problem?  You know what I mean. On the one occasion in a season when you find yourself at sea and in dire  need of them  the batteries will need replacing , the whole thing corroded beyond use (through being stored under wet mooring lines) or you dont have any way to get your illegal flashing lantern to the masthead - and here comes another powerboat - with tinted windows!
  I've tried a few things but nothing I'm happy with. Any bright ideas?

Led navlights by Boatlamps, £30.
Or head torch with red light on left side of head, head torch with green filter on right side of head.
 I actually did this in Cawsand bay very early one morning , but only had red filter!

I made this dodgy device to mount cheapy nav lights on the top of my mizzen. 

The black pole in the photos is an attempt to show how the top of the furled mizzen fits inside the 60mm pvc socket-tube  inside the white wooden box.  This only works with the mizzen furled and it has to taken down to fit the nav lights.  I've not tried it in practice - it may not be easy to fit on a rolling sea in failing light and definitely to be done with care to avoid falling overboard.

The upper bracket is for the white light to provide 360 degree anchor light.

I'm not sure how legal it is but with all due respect to Steve it will be higher than a head torch and maybe a little more directionally stable.

Modern LEDs will be a better option than the cheapy nav lights I've used.

If it works, I wonder if a radar reflector can be fitted in a similar way in the "rain-catcher" position on top of a furled mizzen.

I have been told by a coastguard type that "in extremis" a strong white light shone on the mainsail is an effective (if illegal) way of making sure one can be seen (assuming, of course, that the boat has white sails........).

Not entirely illegal... for those of us with "length challenged" Swallow Yachts the rule (25) says...

"A sailing vessel of less than 7 metres in length shall, if practicable, exhibit the lights prescribed in paragraph (a) or (b) of this Rule, but if she does not, she shall have ready at hand an electric torch or lighted lantern showing a white light which shall be exhibited in sufficient time to prevent collision."

(where the mentioned paragraph (a) stipulated "sidelights and a stern light", and paragraph (b) says they can be combined into a mast top tricolour light).

Seatern has LED side and stern lights and an alternate NASA tricolour/all round white at the mast top. I use a suitable combination of these depending if I am motoring or sailing and whether the mast is raised or lowered.  However seeing any nav lights in Southampton water against the background of shore lights is very difficult.  Shining a torch on the sails may well be the most effective way of making yourself visible.  In that respect, Seatern's tan sails are probably a bad idea! ...but don't tell Matt I said that!

Proper Nav lights as set out in Col Regs are a neither here nor there for  "Four Sisters" and, in fact, for any small boat.

 If the pilot of a LLPG carrier coming up Milford Haven with the flood tide actually saw the little twinkle we could manage there isn't a lot he could do about it.
Flood lights on the sails, a white flare, AIS transmitter, even firing a bazooka at the bridge, wouldn't make any difference......... He can't turn, stop or even slow down  even if he wanted to - which he don't!  A ship like that, aground, is a major story on the evening news.   
If I'm stupid/unlucky enough to be there in the first place (ignoring  all the warnings, Harbour Master's chase boats and the racket on Ch16 ) I'm going to cop it!
No, the real danger to a boat like mine doesn't come from professional mariners. It is other small boats, more specifically, high speed motor boats, that scare me witless. At anything between ten and thirty knots on a coastal run these guys are not expecting to find a small, slow sailing boat in their path.
("Whoops! Where did that little b***er come from? Nearly hit it! Shouldn't be allowed out here with proper boats!")
In my experience, they never slow down, or deviate from their course by more than a fraction and have no idea of the problems their wash can cause a small boat. 
Standard  Nav lights  are good to have. They convey a great deal of information - if they can be seen - but too often they are swamped by shore lights or even lost in the moon's reflection. The MCA should recognise that small boat sailors are the cyclists of the marine environment and lift the ban on flashing masthead lights. Riding a cycle in traffic on a wet winters night with a normal lighting set is suicidal. High intensity flashing LEDs give you a fighting chance of  being seen by approaching motorists, half dazzled by oncoming traffic (why do people insist on using fog lights all the time!) and all convinced that a bike is like a bollard and can be shaved as close as you like!  The latest LED cycle lights are incredibly bright and power efficient - if expensive - and I would rather have something like that at my mast head, flashing its head off, than some feeble MCA approved glim. In Greece this summer I noticed that many  new flotilla boats already  have flashing anchor lights. Who can blame them, but wouldn't it make sense to allocate rapid flashing masthead lights specifically for the use of small, slow vessels which, being unable to take avoiding action themselves, NEED to be seen by other mariners for what they  are as soon as possible?

Tony, I have to disagree with that!  If nothing else "proper nav lights" get you on the correct side of legality which might be important in case of a collision and subsequent insurance claim, or if facing prosecution for violating the colregs!

When I'm on the River Itchen in the dark, the main risk of collision is with people from canoe/rowing clubs training in kayaks and racing row boats.  Some of these carry a light, some have flashing red lights, some have no lights at all and some (if rowing) are facing backwards!  If I collide with any of those, or they collide with me, I prefer to be wearing a halo of legality with regard to my own nav lights.

Out on Southampton water, of course it's up to me to keep well out of the way of shipping.  In the event that a gear failure left me drifting into the shipping channel I would call up VTS (channel 12 in Southampton) and make sure they knew where I was.

I agree that high speed motor boats are a menace.  Fortunately they tend not to be around in the dark or, if they are, they stick to the main/smaller vessel channels which I steer clear of.  Also for them I hope that, if need be,  my AIS and/or radar transponder will trigger one of those red wreck symbols on their chart plotter and they will avoid me for fear of scratching their gel coat. By the way, I don't use a radar reflector because the size we can display is more or less useless!

I'm not sure flashing lights on lots of small boats are a good idea since they will make pilotage at night using lit navigational marks even more difficult. The flashing lights on the Itchen kayakers could easily be confused with the flashing lights on nav marks, particularly port hand or special purpose (yellow) buoys.  The more flashing lights there are, the harder it is to pick out the actual channel.

That said, I suspect flashing lights on small boats will come anyway, just as flashing lights on bikes have done (and indeed have aided safety for cyclists). The relevant rule (Part C rule 20b) says that "no other lights shall be exhibited except such lights as cannot be mistaken for the lights specified in these rules or do not impair their visibility or distinctive character" so a flashing white light carried in addition to standard nav lights might possibly be legal?

As I said, standard Nav Lights on the hull are good to have and I wouldn't be without them for choice but they are not  often visible on a small boat unless its dead calm. A tricolour light at the masthead is better - if you can have a permanent fitting. Otherwise you have problems with zones of visibility.
On my boats permanent fittings are not possible, neither is an AIS transponder (unless there is a pocket sized one on the market now.) I'd rather be seen, flashing illegally, than be legally dead and so I'll continue hoisting an all-round white flashing lantern to my mast head.  If MCA want to prosecute me, they are welcome to try. They've got to see me first ! ( which makes some sort of point, I suppose.)

Re. AIS transponder, not quite pocket size,  but the Digital Yacht GV30 combined AIS and GPS antenna is only about 190mm high and 75mm in diameter (photo attached). The transponder unit can be connected via USB to a laptop running suitable navigation software to give you a cheap* GPS/AIS enabled chartplotter.  It also has NMEA output.

For Mac computers there is Digital Yacht's own Navlink software for which you can get the up to date UKHO charts for around £10.  A Navlink app is available for iPad or iPhone.  The latter integrates with the built in compass and camera so you can point the iPhone/iPad at a buoy and have it identified on the chart!   I reckon that in emergency (e.g. Garmin chartplotter/echo sounder fails) I could use my iPhone for navigation, the only problem being the size of the screen and the capabilities of my eyesight!

*if you discount the cost of the AIS transponder that is!

Hi Peter - Crikey.
An AIS transponder and a SeaMe too?
I know the Solent is busy but isn't that a bit "belt and braces"?
Have you a secret mini nuclear decay source secreted on board providing you with more ballast and the required power? :)

All that electronic gear is a bit rich for my blood!  I spend too long staring at screens as it is and don't want to do it while sailing a small, often wet lugger. No doubt suitable electronic wizardry will soon be available and we will wonder at the foolhardiness of sailing without it.  Until then i'll just lurk in the shallows!

I purchased some months ago the following item: Navilight Tricolor , double magnetic System, superbright, waterproof: http://www.navisafe.com/project/3-navilight-tricolor-2nm-2/
I'm waiting for next season to try it out.

Probably!  But because my jetty is tidal, if I go out on the early tide for a day's sailing I'm often going out through part of Southampton Docks and along Southampton Water in the dark. I stay out of the shipping channel as much as possible, but if there is a "clear channel" ship on the move so does some of the shipping (including the high speed ferries doing 30kts).  There aren't that many small boats around at that time of day, so I'd rather they at least have a chance of knowing I'm there. As Tony has said, nav lights don't show up well, particularly with all the shore lights. Both AIS and a radar transponder can trigger a collision alarm on the Bridge and wake up whoever is on watch!  Larger ships probably have reception of Class B AIS units switched off, but I'd expect the fast ferries to receive class B signals.

In daytime in clear weather I tend to switch both off - although the power they consume is not huge.

Have you a secret mini nuclear decay source secreted on board providing you with more ballast and the required power? :)
Actually I do, but I keep it quiet to avoid the attention of terrorists (or GCHQ). I'll send a personal message!

Hi, Guy.
That looks like a neat bit of kit.
Once you have fixed it to the masthead at the right angle and put the mast up ....how do you switch it on? 
Or does it come with  a light sensing photo cell to do it automatically?

My neighbor  has a  security light like that. It only comes on at dusk. It has a movement sensor, too. Lights up the whole county when my cat walks past it.  Perhaps the same technology could be applied to battery operated mast head lights. 
(Not the movement sensor, obviously. That would be silly. My cat's not a good swimmer.)

Hi Tony,
no, it only comes with the yellow push button on top of the light. I thought one way to install the light would be on top of the mizzen, more easily taken down to switch it on.  Or lower on the boat, right at the bow attached to the SS ribbon. ??
