High Line Yachting is a long-established boating company operating three boatyards west of London on the Grand Union Canal and its arms.

Founded in the early 1970s, the company runs facilities at Iver on the Slough Arm, Northolt on the Paddington Arm, and Cowley Peachey near Uxbridge.

The yards offer a comprehensive range of services for inland waterways boat owners, including engineering workshops, hull gritblasting, chandlery, moorings, and dry storage.

Boat sales are also available, operated in conjunction with Virginia Currer Marine at the Iver site.

The company has grown from a small canal hire fleet to a full-service boatyard operation spanning multiple locations across the waterway network west of London.
