A small craft is not authorised to initiate a starboard-to-starboard passing manoeuvre, but there is nothing to stop a >20m one doing so even if it is used for leisure. We've several times found it convenient to be closer to the right bank of a river when travelling upstream round a bend to port - this puts us on the "wrong" side of course. This is probably one of the most common scenarios for use of the blueboard and/or associated light, and we've never had any problems when meeting commercials coming downstream while doing so.

My recollection is that the visibility range for the scintillating light without a blue board is pretty demanding. My Aquasignal strobe does not meet the requirements.

Yes, one metre is not a lot on a 3,000 tonne ship, but it all depends how the board is mounted. There seems to be no specification but logically it should extend fully above the wheelhouse and be clearly visible as an aberration in the visual profile, a bit like the logo I drew in early Blue Flag’s.

A scintillating strobe light might not be recognised for what it is on a bright sunny day. It could be mistaken for a reflection, but an “incongruous” board will stand out against many backgrounds.

However, as small fry we do not usually (and possibly are not allowed) to instigate a blue board manoeuvre. We simply need to acknowledge receipt of the signal from another, so a flashing light alone might suffice. We have however had occasions on lock approaches etc. where we have made our intentions clear with the blue board, so I would commend the slightly more difficult course of having the board as well, providing it can be incongruous to the profile.

Balliol.

I can certainly see the practicalities of a light rather than a board. I was momentarily nonplussed to have a 120m ship that was coming towards us slide across the river to my starboard side on one occasion before lights became mandatory for day use as well as night; it was very difficult to notice a 1m square board on a vessel of that size.

Thanks everyone. We passed our certificate last year with zero checks on nav lights. Seems it's a highly flexible test! We have a blue board so I'm reinstating it with a light for good measure.

What I find interesting is that not that many people just have a scintillating light, rather than the blue board which seems a lot more difficult to construct than just having the light? My barge used to have a blue flag, now it just has the light and it did pass its community certificate in Belgium without any issues, hopefully it will do the same again with this method this year.

I used a car flasher can for the flash and a pair of waterproof LED lights back to back from the chandler. They are used by the those wishing to be high profile to light the water at the under water of the transom to make mid-night swimmers more attractive to the preditors.

Mine isn't an Aquasignal 25, just something similar from the local chandler when I made the board. It's about 11cm high and 9cm diam in a 70cm board, made in the same way as Colin's.

Thanks Pete,

I struggle to find the dimensions of the aqua signal light. I'd like to know that it fits in my blue board before I commit. How big is yours?

I used a cheap car flasher unit like this with a small all-round lamp like the Aqua-signal 25 .

Hi DBA,

I'm reinstating our ship's blue board. I'm struggling to find a scintillating 360 light. (Knipperlicht in Dutch). Could anyone offer any advice? We're moored in Gouda though can easily shop in the UK. Heading back next month. Despite learning Dutch, I still get great advice from the DBA. The Dutch seem very happy to pay through the nose for things!

My blue board is home-made 60 x 60cm. 50mm aluminium angle welded to make a frame and perforated aluminium panel pop riveted on. Hinge mechanism of 20mm tube inside 30mm tube with nylon bushes. Held down by shock cord, raised by cycle gear cable and sleeving. Very bright scintillating light.
Passed 2 ES-TRIN surveys.

Sorry, the specification for the SRF Blue Board is 70x70cm (not 30x30cm)

Blue boards made of steel can be obtained from SRF Shipbuilding, Harlingen. They are fully automatic, one switch controlling the position and the flashing light. They measure 30x30cm, ideal for a recreational barge, and, according to SRF, acceptable to surveyors. They can be either wheelhouse or pole mounted (preferable if your wheelhouse is either wooden or collapsible).
See attached photograph. Price is quoted as Euros 1,113.20 incl. VAT.

The latest (v5) of CEVNI has yet to be adopted by most countries, but it does still give the same circumspect definition of size at 3.03.3 which is explicitly applied to a board or flag. However at 6.04 (Meeting - Normal Rules) it only allows for a scintillating light with optional board day and night - i.e. there is no mention of a flag there. That is also where the 5cm white border is stated.

That Article also says (to paraphrase) that these sections are not applicable to small craft when meeting a normal vessel or other small craft - i.e they may not initiate a "blue board" scenario - but as Art 3.03.3 specifically defines acceptable size for them it is obviously assumed that a small craft may respond to the intentions of the normal vessel with a board of its own.

Mine is a blue flag on a pole that you slide under the wheelhouse roof (which requires someone to go out and shove it in there).

Doesnt sound like it meets requriements however Ive a year old TRIWV that would suggest otherwise. Used it twice on our trip back from Buzet.

I realise I didn't describe the construction of the one I made for Friesland as you ask in your post, but it is not disimilar to yours - it is shown in use at the top of the link I gave. Mine too had to be 80cm x 80cm to avoid fouling on locksides. I put a lead weight in the angle at the bottom when activated; it is kept in the horizontal position by bungey cord and the weight allows the board to drop into position unaided when the cord is released. It has survived severe winds without damage when in either position as the cord allows a certain amount of movement. It is held on the corner of the wheelhouse roof by stainless bolts with wing-nuts, and the whole thing can be easily detached and put on the roof of the accommodation if necessary on Freycinet waterways with tunnels. I only bothered to do that if the board was on the non-towpath side of the tunnel.

The rules do say that the board should be activated from within the wheelhouse. Mine requires the operator to lean out to release the bungey and then again to refix it, but Peter Voormann accepted that as OK for the Community Certificate.

Blue Boards come within CEVNI at Art 3.03.3 which says they should be "large enough to be easily visible". It quantifies this by saying “this condition shall be considered to be satisfied in all cases if neither the length nor the width is less than 1m, or in the case of a small craft less than 0.60".

I’ve not looked to remind myself of the Article and exact wording but it also says they shall be blue with a 5cm? white border.

As far as usage is concerned my link might help:
