    The Gray Sea Scout listed in The Rudder had a 2:1 reduction gear, but Wm. Atkin specified the engine without reduction gear. That explains the 35 lb.

      The Gray Sea Scout listed in The Rudder had a 2:1 reduction gear, but Wm.
      Atkin specified the engine without reduction gear. That explains the 35
      lb. difference in weight, and of course a reduction gear wouldn't get
      along with RM's small propeller. The reduction gear on those Grays just
      bolts onto the tail end of the reverse gear, so supplying an engine with,
      or without, the reduction was no big deal.

      Heaven, as conventionally conceived, is a place so inane, so
      dull, so useless, so miserable, that nobody has ever ventured to
      describe a whole day in heaven, though plenty of people have
      described a day at the seashore. <G. B. Shaw>
