Looks like another weekend isn't going to go ahead !
Spoke to the guys at Yarmouth yacht station and worked out that getting back from Surligham to Yarmouth for best bridge clearance would mean leaving at about 05.00hrs.
The weather forecast is pretty grim, I've got a bit of a cold and I don't fancy navigating in the dark and damp whilst blowing my nose every two minutes
I'm hatching a plan B as I type this!
