As you say N.E. a very brave couple, in the dim and distant past I have crossed the Atlantic numerous times on vessels larger than the Delux Bathtub featured and not without some "concerns" I must admit
I don't blame them for not mooring in the Marina, the last time I moored there I got a Parking Ticket/Charge as they had changed the free half hour to fifteen minutes, something I had not noticed along with many others apparently. Harriman must need the money to keep his rather nice Motor Yacht (Whisperer?) in Majorca
Stan, when I get all this money from the Government I will have to treat myself to a new iPad as this Steam Driven one is refusing to pick up the item you mention.
