Peter Price gives a lengthy argument that the the reels in Pelorus Jack and
as described in the Manual are not 'tandem' based on a single dictionary
definition starting "in a single line, one behind another;". I was not
involved in the writing of the Manual but in defence of the description, I
note that my current version of the Concise Oxford Dictionary also offers a
definition of tandem as
"a group of two people or machines working together".
