The Isle of Wight Council issued a press release on 27th July 2017 regarding the Lendy Cowes Week floating bridge / Chain Ferry service:
During Lendy Cowes Week 2017, the Cowes floating bridge will offer an extended service during the early hours of the morning, throughout the week.
While over the past fortnight, the floating bridge has ceased operation at 10.30pm, due to the volumes of anticipated users during Lendy Cowes Week, extra sailings have been scheduled.
From Friday, 28th July to Friday, 4th August, the floating bridge will operate daily from 5am (from Cowes) until 1.50am the following morning on a constant basis. There will be extra crossings at 20 minute intervals from each side of the River Medina each night, with the final sailing from Cowes 3.10am.
As usual, on fireworks night (Friday, 4th August) the floating bridge will also operate as a foot passenger only service between 6 and 11pm. Due to the high levels of demand on fireworks night, the Council advises that people purchase their tickets to travel on the floating bridge in advance to ensure the smooth sailing of the bridge at peak travel time between 6 and 11pm.
