Very interesting, thanks for making this video.

I worked in Wilton marina this morning.great place nicely kept.

Hi Simon, Thank you for your comment. Glad you enjoyed the marina.

Good job

How much weight does overplating add to a typical fifty-footer?

[@robertbaxter4021]

Do you have to strip the interior to overplate? Just thinking due to the heat created

[@kyrreforland9466]

Very interesting. Thanks.

Forgive my limited knowledge, but why is the hull overplated and the dead metal not completely cut out and replaced flush with a butt weld instead? Does overplating not produce a capillary joint and the chance of rust creep behind the plate should the weld later rust causing a hidden rust issue over a greater area between the two surfaces?

[@skysurferuk]

Yes.

[@frankiepitt9135]

No, large water tanks have welded joints all round, there is no reason for it to leak if it is done properly. Why should it have a capillary joint leak if it’s a continuous weld. Not a bodge job!

[@gregmark319]

It's just a bodge fix to extend the life of the boat. It's still corroding and they weld onto metal which is being hidden. Many boats get structural failure on the stringer welds because the boat has flexed and then stiffened with new plate, when lifted the stress is then opposite. This continues in the water, but you don't see it until the interior is removed. Over plating is just hiding failure and adding a few years to the boat. Avoid buying one.

how thick do's the hull need to be for it to be insurable?

[@WhiltonMarina]

+marcus klem A narrowboat hull should be at least 4mm thick throughout to be insurable.

Hmmmm how thick is a springer made is that not taken into account

[@julast6658]

@@johnsadler7184 Springers are normally 6 mm and dont rust as fast as other boats as the steel is from cooling/gas storage towers. Premium you might say.

Not impressed by the quality of the welding. Reminds me of my first attempt to weld when I was 11.
