Highway Marine is a boatyard and access point situated on the River Stour above the swing bridge at Sandwich, Kent.

It serves as a useful resource for visiting boaters navigating this stretch of the river, and mariners are encouraged to contact the yard directly for local guidance — including the location of the winding hole above the town, a long unobstructed section of river suitable for turning.

The yard can be reached by phone at 01304 613925. As with other facilities on the Stour, conditions are tide-dependent, so advance contact is advisable before arrival.
