"Three crossing points from the mainland - Lymington to Yarmouth, Portsmouth to Fishbourne (both vehicular and 30-35 minutes) and Portsmouth to Ryan (foot pax catamaran in 15 minutes)."
Plus the red funnel car service Southampton to Cowes, plus iirc, a passenger cat service on the same route, plus of course, my personal favourite, the hovertravel passenger hovercraft from Portsmouth & Southsea to Ryde Esplanade
Is there a reason why you have to travel on Wightlink rather than any other?
