Hi,

I have (another!) question for the group...

I'd like to be able to get into the water to watch the national firework
competition here in Plymouth in August.

Can I get away with a bi-colour nav light on the bow and an all-round white
light on the stern?

My boat is a 14ft Plancraft Stingray.

From the ColRegs: (Rule 23, or thereabouts :-)

Any vessel of less than 7 metres and not capable of exceeding 7 knots
may display an all-round white light, but if possible should also
display side lights (i.e. red/port & green/starboard)

So you're under 7 metres; but if you can do more than 7 knots (or about
9 statute mph) you /must/ have coloured side lights.

My boat is only 5 metres, but has one all-round white on the stub mast
and red/green as appropriate. If nothing else, /I/ feel a damn sight
more secure after sunset :-)

And I would imagine that the waters off Plymouth are a little busier
than here in the Clyde...

Do a search on 'International Regulations for Prevention of Collisions
at Sea'.

Or alternatively sign up for an RYA day skipper or coastal skipper
course. Well worth the effort, IMO.
(But you're not likely to get one before August ;-)
