All the bulkheads, except one, are perpendicular to!
centre line and should be drawn accordingly.!
Double check for perpendicularity by measuring the!
distance between bulkheads at each end. The one that!
is at an angle is also critical since it determines!
the space available in the head, and the length of!
the forward berth. The bulkheads are set!
perpendicular to the waterline. .!
The location of the bulkheads need not be marked!
on the hull since they can be properly located by!
dropping a plumb line or using a level.!
The level, plumb line, chalk line and square are!
all tools required for the above work.!
