There is no Sandbanks ferry service during November.
The vessel is being towed to Southampton for a refit.
There appears to be no alternative crossing available. Wilts & Dorset has an temporary timetable for the 50 route which is running from Bournemouth Square to Studland via Wareham and Swanage. Note that the bus is not starting at Bournemouth Station during November.
