As Alun mentioned Tigerfish can't make it, currently there is no sign of the repaired prop shafts, with it being a bank holiday Monday there is no chance to get the boat ready in time even if they arrived on Tuesday, unlikely by the sound of it so I've had to cancel. Jerry kindly offered me to go with him as he had room for one more.
So it seems there are just 2 boats going. I will be looking to take Tigerfish over with the same crew later in the year if possible.
Just checked the forecast and it looks good!
