This Coastworker 30 (semi displacement) is being built by Graham in Queensland, Australia. On page 1 you will note that the inside of the hull plating has already all blasted and primed which, when building upside down, is a good thing to have done before turning the hull the right way up. The deck can then be made from plates blasted and primed on one side and then the entire outside can be done as one lot after all the welding is finished.
Building the Hull
Stringers notched into frames. Also shown in this shot is the skeg that
has been designed to protect the prop and rudder from damage.
Working first one side then the other The hull plates are
laid and tacked onto the stringers
Fully plated up bow section. Be sure to only tack weld plates
until entire hull is plated
Last plate waiting to be laid on
Fully plated. Notice split pipe rubbing strake, a good thing
to incorporate at this stage.
Turning the Hull
Wheels welded to strongback and entire hull wheeled out of garage.
Rolling the hull over. Plenty of old tyres required here.
Nearly there. Hull weight approx two ton at this stage.
Placed back on strongback in level position for wheeling back inside shed.
