The slipway at Martham Boat Building & Development Company — known locally as Martham Boats — sits on the River Thurne at Cess Road in the heart of the Norfolk Broads.

Founded in 1946, the boatyard has long served as a practical access point to the river, supporting the launch and recovery of the traditional wooden cruisers, sailing yachts, and day launches that the yard is known for.

The site on Cess Road provides direct river access to the Thurne, placing boaters within easy reach of the broader Broads waterway network.

The boatyard's quay heading and riverbank also offer mooring for visiting craft, making the slipway a useful facility for both the yard's own hire fleet and those arriving independently by water.
