Narrowboat Welding, Plating and Stretching


As your narrowboat becomes older, the steel work is subject to corrosion and wear which leads to thinning of the metal, which may at some stage need overplating.

Overplating is a way of increasing your narrowboat’s life span to get many more year’s of fun out of it.

At Swanley Bridge marina we have a dedicated welding and engineering workshop, which has a unique plating table system and lifting equipment, all designed and built by Danny,D and J Engineering, our narrowboat engineer who has over thirty years of welding and engineering experience in both industrial and marine. The plating table gives correct support when welding and also has tooling for clamping the narrowboat sides to stop them from spreading and correct re-alignment when stretching boats.

The welding processes we use are correct “v” joints to gain full penetration and high current fillet joints with top of the range welding equipment.

When plating a narrowboat whether it’s a new bottom, sides or both, attention to the extra weight added (which makes it sit lower in the water) has to be paid to the hull opening and outlets so they maintain the correct height above the water line (free board) so re-ballasting, lifting sink outlets, raising weed hatch trunks etc is all taken into account to keep your boat correct for the insurance company.

Here at Swanley we prides ourselves on the excellent standard of narrowboat welding, whether it is replating a narrowboat, general welding repairs or new fabrication work, the attention to detail is second to none.

We also offer a narrowboat stretching service if you want to to keep your boat, but would like to have a bit more room, either steel work only, or a full fit out or re-paint can be organised through our independent team who work out of Swanley Bridge Marina.

So if you have any welding work, whether plating work for surveys, alterations or cosmetics, come and discuss your needs with Danny – his motto is “if man made it, man can fix it”
