Has gone through several stages over a number of
years: Why set up a full frame shape, when much of
the information and control of the shape can be in
the part from which the hull is shaped? Today, we
take a flat panel, lay it onto 11 simple frames which
are positioned to locations marked on the panel and with
the addition of a few short cuts and grooves, we pull it
to the final hull shape. We have replaced miles of strip
with a few short cuts to achieve the same effect. Even the
largest hulls are completed without the boat builder moving
off the shop floor
I describe the start of KSS, in 1991, as the time we moved away
from conventional thinking for hull making. We eliminated the
need for a full hull mould shape to work on and we put some of
the hull shaping control into the panel itself. We made hulls
in a lot less time than we previously spent on getting the shape
set up. However, we have just made an important step in the
refinement of KSS shaping.
We now design for half hull shells to be shaped before bringing
together to form the full hull. We think of a hull as a unit and
the idea that it might be made more efficiently in two halves just
did not occur to me till now.
There are a number of advantages to the half shell. Better
accessibility is the most important. I see it as the perfect
compliment to KSS Modular Assembly - which is also based on arranging that all
tasks can be done when easily accessible.
We have no particular plans to change our hull shapes. Yet,
this shaping process is more versatile and does open up a few options
that we will make use of in the future. This does make KSS available
to monos, but not sure when we will find the time.
NO TORTURING.
Torture ply and KSS hull shaping have nothing in common. The compound
curvature is achieved by using short dart cuts and nothing is forced or
stretched unduely. Allow the shape to take place. Open up the dart
cuts if they close down hard. This way there are no built in stresses in
the final hull. The other misconception is that the panel is only part
cured while shaping. Allow to fully cure before shaping. One point to
appreciate here is that there is some tendency for the bend to extend into
the topside area. We encourage this by the placement of the inside skin
before shaping and by the length and position of the dart cuts.
