the main superstructure has now been filled and sanded to my satisfaction and have started building up the upper wheelhouse ready for moulding. the top part of it which has been added since the other photos were taken is purely the wind break on the top of the wheel house, but I thought it easier to make this as one with the grp mould and then just add a top deck of ply, than to get a thin plastic( or Ply) wind break made to contour to all the curves and shapes.
this will all be sanded, filled, sanded again and then clad in card to pick out the windows and door ways before moulding.
