Weltonfield Narrowboats is based at Welton Hythe marina on the Leicester Section of the Grand Union Canal, roughly half a mile from the main line at Norton Junction near Daventry, Northamptonshire.

The company was founded in 1975 and operates two rural marinas — Welton Hythe and Welton Haven — set in open English countryside.

The location sits at the heart of the canal network, giving boaters access to eight cruising routes and placing them within a day's travel of major junctions at Gayton, Braunston, and Napton.

Marina facilities include non-slip staging walkways, gated access, car parking, toilet blocks, and metered electricity.

A boatyard at Welton Hythe provides a full range of services including engine servicing, electrical and gas work, pump-outs, diesel, and blacking.
