Option 1: a vessel not under command, carrying a pilot.

three vert reds is Restricted by Draft, but normal steaming lights needed. Could be RBD at anchor ?

A vessel constrained by her draft needs to be following a course (definitions). It can't be at anchor therefore.
A vessel not under command does not show mastlights - only sidelights and sternlight, when making way through the water, and there is no mention of sidelights or sternlight, so its not making way.
A pilot vessel when unable top manouevre as required by the rules, due to some exceptional circumstance, could possibly be NUC. She's not making way through the water, so switches out her sidelights and sternlight.
Its not one I've ever seen before, but I'd go with the pilot vessel NUC - they break down sometimes too.

I thought at first it was a stern view of a vessel constrained by her draft but the white stern light would not be above the 3 reds.

Pretty sure its Vessel constrained by draft, less than 50 meters in length
I just look on the sticker on the door when not sure.

If you mean the white masthead light - that is not visible from astern

Is it not a vessel that is NUC underway under power, viewed from the port side?

So what would the white light be if that was the case ? NUC does not show mastlights.

I think it must be a vessel constrained by draft seen from so close in front that the port and starboard lights are obscured by the hull and the two masthead whites are in line.

I've got it 
It's a sailing ship under 20m, with a pilot on board, carrying explosives, underway. Seen from port for'd.
Do I get the beer ?

Sailing vessel constricted by draught <12m from stern with masthead tricolour

Its a large yellow cabin RIB, looks like a pilot vessel, was on www.rib.net , so not CBD or over 50m.
white over red = pilot,
Would it show these as well as NUC?
This seems possible solution.
White + 2 reds = aground, but its also showing a third red.

Vessel constrained by her draught
Power-driven vessel restricted to a narrow channel by her draught and thus unable to deviate from course.
Lights for power-driven vessel under way and three all-round red lights.

The picture on the link you posted doesn't show any lights (that I can see, perhaps my eyes need testing ;-) )
