Is the Portland Light that flashes differently at different angles a type of Vector Light? I have seen (on the west side of the Atlantic) vector approach lights that replaced range lights and show different colors depending on the angles. Perhaps you could explain vector lights sometime(?)
Portland Bill LH has various sectors in angles, such that you see 4 flashes when perpendicular to the coast. As your angle to the coast gets less, the number of flashes gets less.

Update: No Condor high-speed ferries operate from Weymouth now.
So sad, the cross channel ferries made Weymouth the gateway to the UK
@@CoastalSafety yes, it is more than sad. I love your presentation, it's so informative.
