I live in Stevenage, Hertfordshire, England. I travelled to the Isle of Wight by train and catamaran. My journey was train to Kings Cross, then tube to Waterloo and train again to Portsmouth harbour; from there a catamaran whisks you over to Ryde in no time at all.
Car ferries go from Lymington - Yarmouth, Southampton - Cowes, Portsmouth - Fishbourne, or passenger only hovercraft Southsea - Ryde.
