Question: What is the blue and yellow light ahead?
Bill and Rose are on board
Emma, a 13m cruising yacht.
They are on passage from Falmouth to southern Ireland.
Although Bill and Rose both took an RYA Coastal Skipper/Yachtmaster shorebased course about 20 years ago, they are cautious navigators.
The passage plan is to set off from Falmouth in the evening and leave the Isles of Scilly to starboard.
