Six-person rowing shell

Defined rigged mass: 100 kg; defined specimen; range 85 kg–120 kg.

A defined six-person sweep-rowing shell 13.4 m long and 100 kg when rigged but without crew or oars. Sixes are not an Olympic standard class, so builders, coxing layouts and shell dimensions vary.

How to read the visual

The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.

  • We use 100 kg for the rigged mass of a six-person rowing shell; the recorded range is 85 kg–120 kg.
  • The rigged mass of a six-person rowing shell: This is an illustrative comparison value, not a claim that every example is the same.
  • The recorded ranges overlap, so the ordering can vary even though the central values differ.

Mass is distinct from weight: an object’s mass stays the same as gravity changes.
