The Ferryman 6.4m wide tunnel is one of the strongest polytunnels available in the United Kingdom. The hoops are made from 60mm Z35 structural steel tube which compares with other tunnels using 50mm diameter tube. The ridge and bracing tubes are in 44.45mm (1¾") diameter tube. All the frame components are made from pre-galvanised steel tube which offers outstanding protection. The 2m hoop spacing gives unrivalled strength and ensures easy cladding with a tight, smooth cover.

The Ferryman tunnel has a number of unique features. Among these are the sleeve fit hoop connectors which eliminate awkward bolted clamps leaving a smooth hoop surface. The door frame 'goal posts' at each end are already rebated to make the positioning of the door frames a simple, accurate and strong job. Double hinged doors can be supplied as an extra item, the ready to build kit comes pre-jointed with polythene to cover the doors and infills.

The curved shape of the 6.4m tunnel adds to its windcheating design, however the whole floor are is usable and the short straight side ensures that cultivation is possible (with care) right up to the polythene. 6' height is available just 760mm (30") in from the base, and the height at the ridge is 3m (10').

The 7.3m wide tunnel has a 1m straight side and is of similar construction and dimension to the 6.4m tunnel with the following exception : Width 7.3m (24' 0")
