Night diving

[cool_running]

A friend has suggested there should be a light set up for my boat to indicate divers in the water at night, i have a diving flag but cannot find any reference to light configurations, any help/ideas would be much appreciated.

There is no set signal for diver down at night,that I am aware of. but surggest you put a working light similar to the ones the fishing vessels use to shine down on the boat that also shines on the flag.This would probably work. /forums/images/icons/smile.gif

During night diving a boat should show the International lights to indicate that "a vessel is restricted in her ability to manoeuvre". These are three lights in a vertical line, the top and bottom are red and the middle one is white.

(Technically speaking, dive boats should show day signals ball, diamond, ball as well as the flag, but only pro boats seem to do this)

Isn't there something in C.E.V.N.I that mentions a board with three lamps arranged in a triangular configuration, used for night diving, or am I getting confused with something else?

Brendan has given you the correct answer.

BUT you do not state what sort of vessel you will be using for your night dive , because a 6.5 mt RhIB does not have to show any lights at all , apart from a ALL ROUND WHITE light.

ps, basically a lot of rib's just fly the 'A' flag when divers are down... When i have divers down on our club boat which is a hard boat of 45 ft , we do fly a RIGID 1 meter sqaure 'A' flag,, we do not conduct night dives .

My charter vessel on night dives show RAM lights as well as normal Nav lights , as boat patrols area of the dive site.

All i have in my book,says 2 red with white in middle shows in ability to manoeurve but still under way.......the whole think is mind blowing, but i would really like to show something. What about anchor lights and 2 red lights(all round) in a vertical line...(vessel aground)
Just guessing really,please keep thinking......
Really need to do something....pitch dark here 24 hours a day........

Uhhhmmm! which book are you looking in?
Red white red is correct international signal

If you look on the internet, the red white red lights at night are mentioned in many diving clubs websites

-------------------
Signals for dredging or underwater operations

4.1 Vessels engaged in dredging or underwater operations, when restricted in their ability to manoeuvre, are required to

display the lights and shapes as described in Rule 27(b) and (d).

4.2 A rigid replica of the International Code Flag "A" is an acceptable alternative to the shapes specified in Rule 27 (d). This

provision only applies to small vessels restricted in their ability to manoeuvre and that are engaged in diving operations.

Vessels engaged in dredging and underwater operations, other than diving, are not permitted to use this signal.

4.3 This rigid replica is to be displayed on board the vessel to ensure its all-round visibility and is to be not less than 1 metre

in height to ensure that mariners in the vicinity can clearly see it and take appropriate action.

4.4 In waters where small vessels frequently operate, mariners will often see the "Div er Down" flag on floats or buoys. This

flag is red with a diagonal white stripe running from the top of the hoist to the bottom of the fly and indicates an area

where scuba diving or other diving activity is in progress. Vessels should keep well clear and proceed at slow speed.

4.5 Despite its general use, the "Diver Down" flag is not a substitute for the "A" flag, required by these regulations

If there's any diving at night on my boat ..... the lights will be out. Mr B is shy

[cool_running]

Ok, so what we are saying is i should go with the red,white,red config, high up the mast below the mast light or incorporating the mast light, it would be know problem to fit a red light above and below the mast light with a seperate switch,........What say you to that !!!!!!

Ps Where on internet?

[BrendanS]

Should be seperate to normal anchor or steaming lights.

when I type in diving signals night into google, this is the first site that appears., Show the lights clearly. <A target="_blank" HREF=http://www.dpi.wa.gov.au/imarine/rec_boating/regulations/diving.htm>http://www.dpi.wa.gov.au/imarine/rec_boating/regulations/diving.htm</A>

Did you see DeepAndy's response by the way - he's a diver.

[cool_running]

Yes,got andys message,it would not matter surely if it incorporated mast light while anchored,have anchor light aswell on stern, during normal running only nav lights would be on not 2 additional red ones.......
Will take alook at internet aswell
Thanks

You should technically have normal anchor lights showing as well as red white red, though I don't suppose anyone's going to be too bothered (unless there is an accident and investigation)

If you have divers in the water I would not recommend anchoring. You need to act as a mother hen guarding her clutch (or should that be flock?). All divers should have smbs (surface marker buoys) unless on a shot line, all should have lights or light sticks attached.

Nite diving is great fun but needs to be properly organised and everyone needs to be properly instructed as to what will happen when they surface and in case of an emergency. It is magical to see the phosphorescence and the fish life and different colours in the torch lite.

A vessel engaged in underwater work would not show any other lights other than red whte red and safe side and danger side lights if showing red white red and anchor light this could be mistaken for a fishing vessle depends on size of your vessle and where the all round light is placed if you are showing the wrong lights and an accedent occurs then you could be liable. you could go for masthead all round white at anchor and deck lights, it all depends how busy the area is how far away the divers are from the dive boat, if they are showing an smb, it wont be much good showing divers down if they surface 1000mtrs away or more! in a busy lane. probably the safe bet is to cover with small rib or tender following a smb.

Or if in area where strong current then a line leading back to anchor or shot line should be used then they will have the safety of the dive vessel, when returning to the surface.

[BrendanS]

You're complicating things. Doesn't need to show safe and danger side. See e. Does need to show steaming lights
(d) A vessel engaged in dredging or underwater operations, when restricted in her ability to manoeuvre, shall exhibit the lights and shapes prescribed in sub-paragraphs (b)(i), (ii) and (iii) of this Rule and shall in addition, when an obstruction exists, exhibit:
(i) two all-round red lights or two balls in a vertical line to indicate the side on which the obstruction exists;
(ii) two all-round green lights or two diamonds in a vertical line to indicate the side on which another vessel may pass;
(iii) when at anchor, the lights or shapes prescribed in this paragraph instead of the lights or shape prescribed in Rule 30.

(e) Whenever the size of a vessel engaged in diving operations makes it impracticable to exhibit all lights and shapes prescribed in paragraph (d) of this Rule, the following shall be exhibited:
(i) three all-round lights in a vertical line where they can best be seen. The highest and lowest of these lights shall be red and the middle light shall be white;
(ii) a rigid replica of the International Code flag "A" not less than 1 metre in height. Measures shall be taken to ensure its all-round visibility.

you'll notice the reference to section b which states

(b) A vessel restricted in her ability to manoeuvre, except a vessel engaged in mine-clearance operations, shall exhibit:
(i) three all-round lights in a vertical line where they can best be seen. The highest and lowest of these lights shall be red and the middle light shall be white;
(ii) three shapes in a vertical line where they can best be seen. The highest and lowest of these shapes shall be balls and the middle one a diamond;
(iii) when making way through the water, a masthead light or lights, sidelights and a sternlight, in addition to the lights prescribed in sub-paragraph (i);
(iv) when at anchor, in addition to the lights or shapes prescribed in sub-paragraphs (i) and (ii), the light, lights or shape prescribed in Rule 30.

But showing the steaming light means she is under way, this dive boat is at anchor!
a non commercial dive boat at anchor is not restrited in her ability to manoeuvre, what is the size of boat? a small pleasure craft would not need to show complicated signals and would not be equiped to display them. I was just explaing the use of boat that is undertaking underwater activities, This could be a dredger.

[BrendanS]

Red over white over red are the lights you display if divers down at night. Doesn't matter if commercial or not. Nothing complicated about it. CoolRunning asked what he needs to display. Red over white over red is the answer.

Where did dredging come into it? Cool Running isn't planning on doing any dredging.

As Duncan stated, boat shouldn't be at anchor but following divers - in which case steaming lights are needed
