This will also be able to turn on just the anchor light but without interfering with the port and starboard as they are electrically isolated on the first switch. Sounds complicated, but really is quite simple. Suppose I could do a little diagram if anyone's interested. Works well on my boat anyway.
BP has a Carling switch that is on-off-on, the first on position puts on all 3 lights- alround white, port,stbd. The second on position just puts on the allround white. I haven't given much thought as to how it sorts it out internally, there might be a diode involved or multiple poles. I'll try & think it out, in one of my many moments of relaxation

Nav lights

I've got the Carling switch on Viper, works well and with all round white above the Echomax its pretty much 1m above the Navs too.

Really? My set up must be pretty close to legal if it is not (they are as far apart as I could get them) and I only have a 4m boat with no A frame.

One of the bigger problems with the 1m separation on Ribs is that once the boat is running & the bow has risen, the toobs can obscure the R/G from the front. I could easily get 1m if I park the R/G at top of toob level, but I know they won't be seen as soon as I get on the plane.

Right now mine are well too close. One of the winter projects is a second ARW on a pole, and replace the bulb in the current one with an LED.

Theory being if the main packs up, or I'm using it as an anchor light it won't guzzle the battery. (with aux there's no way I'll be doing 7 knots - or charging the battery!)

How many folk actually anchor the boat at night and need an anchor light?
I have only done it a couple of times and there was nobody about that would have seen it anyway?
Its not as if a boat being left on a mooring will be lit

Mine, as far as running lights are concerned, is legal with P&S lights well outboard visible from the front and an ARW 110cm above this....then again I set my lighting up to enable night running to be easily practicable as we do it regularly. (and dark up here does mean dark, no lit coastlines to see anything by)

However I agree most RIB's aren't set up to be able to do this and most A frames not high enough.

or this :

But even if not perfectly legal, would say that on a rib a round white + sidelights should be fine, it does not make that big difference in real life.

a lot of people mount a tricolour cluster on the top of the frame - these are intended for use on the top of a mast and are not legal for use on a rib. mine are not legal at the moment as there is only 600mm between lights, but is on the list of winter projects!

I have seen professionally owned RIBs use the Tricolour. I have also seen a yacht using the Tricolour at night without sail.

My RIB has about 900mm between lights. The Red and Green have a flat plate on the A frame about 300 mm below the top. Using a 600mm S/S pole this takes the distance between all round white and R/G to 900mm. Just short.

I did have a bigger plastic pole on it but one lunch time in Seahouses harbour, I came back to find it dangling by the wires. I never did find out how it happened.

Is an RYA examiner going to be pedantic about the exact distance on a RIB?
