CONSTRUCTION
METHODS
HASB custom
build:
- to any
international classification and
survey
- to ABS
standards for racing yachts
- to any
length
The success of
high profile racers such as 1991 BOC place
winners Innkeeper and Buttercup and more
recently Bobsled, Frantic, Hammer of Queensland
and Animal Farm have gained HASB a reputation
for the highest standards, building fast,
strong, safe boats able to withstand the
toughest conditions.
ALUMINUM
- is a low
density, light but strong material that can
be used in all types of vessels - even very
light displacement vessels.
- is very easy
to shape which gives the designer much more
scope to create a work of art - flowing lines
and radius's
- extrusions
come in all shapes, profiles and sizes which
can save money in the construction and add
strength to the structural members.
- does not
require painting.
- is very
corrosion resistant and only requires
antifouling.
- does not
require sandblasting, is recyclable and
environmently friendly.
- is far
superior to GRP, traditional wood hull or
cold moulded vessels when it comes to impact
and abrasion damage control.
STEEL
The contemporary
steel boat is a very different proposition to
those in past times. Modern technology produces:
- hulls with
rounded bilges, soft shapes, NACA section
keels and performance underbodies protected
by low maintenance marine coatings
- weight
reduction by building deck and cabin
structures from aluminium, fibreglass or
composite materials.
- polished
stainless steel deck fittings.
There are many
challenges to face in ocean sailing. When the
hazards of floating debris, half submerged
containers and weather patterns that defy
prediction are considered, the advantages of
building a very tough steel boat are obvious.
The hull, deck
and keel are all one integrated structure. This
entirely eliminates leaks and adds strength.
Because of the
added strength, bulkheads are reduced which
gives greater scope for the interior design and
fit out.
ALUMINIUM &
STEEL
The combination
of a steel hull and aluminium superstructure
provides strength and toughness below water as
well as light weight strength above. Special
techniques for joining the aluminium deck to the
steel hull, normally associated with Naval
vessels, are required.
The technique is
referred to as a structural transition joint
(STJ). It's cross section consists of an
explosion bonded composite of seawater resistant
aluminium alloy and C-steel and is usually
applied in the form of strips or pads when
welding together steel and aluminium
structures.

HASB is noted
for their ability to interpret and implement
naval architects and engineers requirements. We
enjoy a close relationship with the designers;
the combined efforts of HASB and the designer
ensure an outstanding finished
product.
