is necessary structurally (fore-aft strength for the mast step), plus
the entire flat front serves to encase the wooden truss that serves to
provide vertical support for the mast step, and bilateral strength &
stiffness connecting the hulls together and resisting the vertical
force vector caused by the mast stays..
(This truss could be open air but...) I am guessing that PCB figured
that being that the purpose of this design concept was "a cruiser" and
that staying dry is key towards comfortable cruising, that enclosing
the front wall would serve as an effective spray screen. Certainly,
the sponsons would be raising splashes and wind spray while sailing
