20 tonnes
The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.
Canal narrowboat
A defined 17.7 m cruising narrowboat displacing 18 tonnes and travelling at 1.8 m/s. Bow-to-stern hull length excludes removable fenders; fit-out, loading and waterway dimensions vary.
Canal & River Trust — Boats and boating
The marked defined displacement mass is calibrated. Unmeasured illustration details are representative.

Why these numbers?
The visual compares mass with defined displacement mass. The records below preserve each value’s basis and caveats.

- Comparing
- Mass ↔ Defined displacement mass
- Relative size
- 20 tonnes is larger on this measurement by a factor of about 1.11. 20 tonnes's selected measurement is approximately 11.1% greater than Canal narrowboat's.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Canal narrowboat uses a 18 t central value within a recorded range of 14 t–22 t.
- Canal narrowboat is labelled defined specimen; treat the displayed value as a comparison anchor rather than false precision.
- The recorded ranges overlap, so the ordering can vary even though the central values differ.
