DETAIL DESIGN
The design team at CLD now finalise all details as defined in the design
agreement in order to furnish the chosen yard with information to ‘build’
the boat. A typical package includes comprehensive drawings covering structures,
systems, interior/exterior fit out and custom items. The actual design
is still relatively fluid within the confines of the preliminary design
and it is possible to make minor alterations to layouts and systems.
Generally the package contains the following:
1. A 50~200 page specification detailing
every aspect of the vessel, its construction, systems, fit-out, finish
and classification requirements.
2. A detailed weight study listing the
weight and location of all structure and onboard components to predict
the position of the longitudinal, vertical and transverse centre of gravity
for the vessel.
3. A hydrostatics report and stability
booklet giving floatation etc for different loading conditions based on
a 3D computer generated surface model.
4. Powering and speed estimates based
on accurate data and prediction methods combined with model testing where
appropriate.
5. 3D visualisation renderings that
give an idea of the aesthetics before the vessel is built.
6. A thorough drawing package detailing
geometry, structures, arrangements and systems.
The following images represent a typical drawing package submitted for
the ‘build’ phase. This particular vessel
is a 14m crew boat, built in aluminium alloy and has a full set of cut
files generated and nested for CNC cutting. Actual drawings are provided
to scale in both A1 and A3 format as required.
