    Well, my own boat is under 7 metres (around 6.7) but she doesn't carry
    batteries, mostly because I have no way to keep them charged when she is
    on her mooring, and there is no practical way to mount kerosene lamps so
    that the colours show in their appropriate sectors. I'm not about to
    undertake offshore passages at night in her but we do get fog here (when
    the ColRegs require nav lights) and I can operate into the dusk. An
    all-round white light, supplemented with a flashlight in time to avoid a
    collision, as per the ColRegs, seems sensible to me.
    
    At under 7 metres, hull speed tops out at about 6 knots but we mostly
    plod along at 2 or 3. If some passing powerboat chooses to interpret our
    white light as an anchor light or a stern light, it wouldn't make much
    difference. Either way, we form a near-static obstacle that the
    powerboat is supposed to avoid.
