The best bit about travelling to a destination by boat is the travelling by boat! However I’ve never experienced a rough boat trip, so it may not always be the case. The first of our voyages during our 48 hours in Lymington was the round trip to Yarmouth on the Isle of Wight.

You should! Also, Yarmouth is a very charming little town (village?) with coastal walks and bus connections to the rest of the island.
