Sub-para.  (d).  —  If  the  crew  are  not  berthed  in  the  bridge-
house,  and  the  arrangements  to  enable  them  to  get  backwards
and  forwards  from  their  quarters  are  not  satisfactory,  an  ad-
dition should  be  made  to  the  freeboard  of  1  per  cent  of  the
moulded  depth  of  the  ship  in  the  case  of  vessels  180  feet  or
more  in  length  and  having  wells  70  feet  or  less  in  length.  If
the  vessel's  length  does  not  exceed  150  feet,  or  if  the  well  is  80
feet  or  more  in  length,  the  foregoing  addition  will  not  be  re-
quired.   In  the  case  of  vessels  between  150  and  180  feet  in

length,  or  having  wells  between  70  and  80  feet  in  length,  the
addition  is  to  be  found  by  interpolation.
Planks  secured  in  position  by  lashings  are  not  to  be  regarded
as  satisfactory  arrangements;  and  a  gangway  providing  access
between  the  bridge-house  and  forecastle  cannot  be  considered
satisfactory,  unless  the  following  requirements  at  least  are
complied  with:

The  gangway  to  be  not  less  than  18  inches  wide  and  to  be
efficiently  supported  at  suitable  intervals.  The  ends  to  be
strongly  bolted  to  lugs  riveted  to  the  bulkheads  of  bridge  and
forecastle,  or  to  the  hatch  coamings,  or  to  iron  standards  bolted
to  the  deck  or  to  be  secured  in  some  equally  efficient  manner.
The  top  of  the  gangway  to  be  not  less  than  2  feet  6  inches
above  the  top  of  the  deck  at  any  part.  A  life-line  or  rail  to  be
fitted  for  the  entire  length  of  the  gangway  and  to  be  supported
by  wrought-iron  stanchions  suitably  spaced  and  not  less  than
2  feet  6  inches  in  height.
