A painted yacht on a silver sea

On our way back, somewhere near Frinton, no wind, tide just turning in our favour and 6 hours to go.
We put our sails up 10 minutes ago - didn't do any good - but this guy saw what we did and followed suit.
Didn't do him any good either.
By golly the rattle of a single cylinder diesel can really get on your wits after a bit.
