The mainmast step is on the lower deck, the reason for notcontinuing the mast down into the hold being that it is considereddesirable that the passage between the engine and boiler roomsshould be kept clear. The details of the step are given in eleva-tion and athwartship view in Fig. 227. In order to strengthenthe deck-framing in wake of the step, middle-line carlings, c, c, arefitted between the beams, and a deep longitudinal girder a, formed 286 Miscellaneo
