I went to the piers again today. In particular I searched Bankside pier, as it's the fourth pier along from the 'Kemble' end, and it's on the
right hand side of the river. It's hard to look for anything in London without looking like a terrorist, but I've done my best here! It's definitely not at the bank pier.
After a tiresome wait spent piering[sic] into dustbins and behind signs, the Typhoon finally arrived and I 'embarked'. It was my third search of the boat itself, I was very thorough, and I hope Lodgecrest will agree that it is almost certainly not on board.
I was unfortunate enough to be one of the ones who travelled all the way to the IOW, on more than one occasion, only to return home empty handed, and I have to say that being on the piers and the catamaran didn't feel the same. On the IOW search there was a (justified!) feeling that I was so close; with this it feels like a wrong turn.
I'm living in London so I'll keep scouring the boat/piers till kingdom come if needs be, but I think an extra line to the clue would hot the search up.
