Cross-Solent operator, Red Funnel, has announced changes to its timetable which will affect customers heading to and from Southampton today (Friday).
Ten of its crossings will be withdrawn for passengers and will operate as freight only sailings.
From Southampton, they include the 5.15am, 8.15am and 11.15am crossings. From East Cowes, the 6.40am, 9.40am and 12.40pm sailings will be disrupted.
Later on in the day, more crossings have been cancelled. Red Funnel says the problems have been caused by ongoing essential maintenance on one of its fleet.
This afternoon, the 2.15pm and 5.15pm sailings from Southampton and the 3.45pm and 6.45pm sailings from East Cowes have been withdrawn.
