Boat Forum / Building / July 2005

Hi William,

the laminated ribs should provide the shape of the hull, just the same
as traditional plank on frame construction.

Hi.
With small hulls you most often can rely on the panel strength , you
hardly need any ribs and having no ribs also mean that you can't make
the most important part in terms of creating structural strength, --
the stringer.
But at some point with just some size boat hull, you will need the box
structure at some point you can not rely on only the "strength" of the
panels, you need a few stringers ,an extreme strong part of the boats
structure , then the box structure follow the shape of the hull as it
is made panel-rib-stringer. A 3D-H framework are making it all into a
box structure.
Now if you are not to build the hull anyway, you can say whatever you
want, --- but if you realy want to do reliable works drawings, you need
to know and understand the feature that nomatter what modern material,
are the fundamental part of it -- the box structure created as soon you
strongly attach a stringer. Now you can make all the most fancy
drawings you please, but fact is, that when you understand the
fundamentals , what make the hull, from a shivering collection of
panels, into a rugid structure ;--  with the 3D-Honeycomb you both
avoid the lofting and get a set of frames that will form just any shape
keep that shape while you slot assemble the frames so each frame are
allready from the basics , supporting and supported by all other
frames, one huge collection of ready to cover cubes, and at the same
time, when you cover inside and outside with panels, you get a boat
hull capable of twisting , something that only add speed btw. a sort of
strength that is very important for a boat hull ,
The most important issue building from panels and frames are, to have a
reliable framework to attach the panels, a framework that will not bend
or move, a 3D-Honeycomb framework produce just that, produce an extreme
strong framework for any shape hull.  ------ insert a 3D model of the
engine ,subtract that from the 3D model and when frames are cut and
assembled, the engine bed are there allready.
