3.0 CONSTRUCTION
3.1 Hull
The hull of the Tartan 4000 is a single unit fiberglass molding which incorporates a
specially developed NPG/ISO gelcoated hull with a resin infused modified epoxy laminate.
Alternating layers of strand mat and mulit-‐axial glass in modified epoxy resin are locally
reinforced and cored with closed cell synthetic foam in order to achieve an optimum
balance of strength, stiffness and weight in the laminate composite.
The construction process ensures the complete weaning of the laminate complex with
minimal voids or bubbles. Extra laminate is used in any area that would be subject to
additional stresses. The exterior finish consists of gelcoat molded into the fiberglass.
The boot stripe is applied using PPG Concept Acrylic Urethane while the cove stripe is
a premium vinyl film. A synthetic foam core is sandwiched between the laminate
layers to add significant strength and stiffness properties to the hull, and yet ensuring
that overall weight is kept to a minimum. The strength/weight characteristic of the
sandwich composite as well as resistance to impact and abrasion is magnified by the use
of multi-‐axial glass in the laminate.
3.2 Deck
The deck and cockpit, like the hull, is a single unit fiberglass molding with a gelcoat
surface. A balsa core is incorporated into the structure between the laminate layers for
additional stiffness. A non-‐skid finish is molded into the working areas of the deck.
3.3 Hull / Deck Joint
The top flange of the hull is capped with marine adhesive sealant. The deck is then
fitted and fastened through the Teak or Aluminum toerail by means of stainless steel
bolts. As the bolts are tightened, the sealant is forced into exposed crevices. If a leak
should ever develop in the hull / deck joint, the through bolts may be tightened
accordingly.
3.4 Rudder & Steering
The rudder is constructed of two molded composite shells, which are bonded together
and injected with two-‐part foam for added strength. The rudderpost is carbon fiber
with a reinforcing web positioned within the rudder.
Wheel steering is standard. The steering system is a smooth operating wire rope; Edson
steering system. The steering manufacturer has provided maintenance instructions
