Hull
The hull is built in a
sandwich construction of multiaxial glass fibre reinforced ISO polyester. The
hull is extra shielded with Twaron (with guarantee certificate). The surface
layer is of NGA gelcoat for maximum protection against water penetration. A
core of balsa for strength and insulation. At the stern there is an integral
swimming platform with a bathing and safety ladder. The bilge is reinforced
with a longitudinal and transverse floor plate construction. This supports keel
fittings, mast, engineframe, tank and cabin soles. Additional reinforcements
longitudinal in the hull as stringers. All main bulkheads are laminated and
bolted on both sides to the hull. Transverse chain plate fittings laminated to
the hull. The rubbing strake colour is white with carmine red trim line and water
lines laid in the gelcoat. Below the waterline the hull is treated with epoxy
primer and antifouling paint. The hull is topcoated internally. Extra
watertight bulkhead between cargo hold and forward cabins. Stainless steel
through hull exhaust fittings for engine and generator. Earthplate 3 sqm
equivalent stern portside.
Keel
The entire keel is built by
NACA profiles. The lead keel is bolted on with 14 x 20 mm acid resistant
stainless steel bolts. A small wing at the bottom of the keel reduces the water
flow beneath the keel, which results in less drag.
Rudder and Steering
Rudder and skeg in NACA
profile. Semi-balanced rudder in glass fibre reinforced polyester with 60 nm
acid resistant stainless steel rudder post. Rudder fitting in stainless steel, bolted
to the skeg. Steering pedestral (by solimar) in glass fibre reinforced
polyester with leather covered stainless steel wheel of diameter 1200 mm.
Compass and top-fitted single lever control for the engine and engine board.
Friction brake on the wheel. Stainless steel chain and wire cable to a large
quadrant. Rudder post scaled with greased stuffing box. Emergency steering on
rudder post by tiller.
Tanks

resistant stainless steel installed between floor plate construction to port
and starboard sides. The tanks are fitted with inspection hatches. Fuel tanks
in stainless steel installed between floor plate construction amidships
inclusive lever gauge. Suction pipe with manual pump to the tank bottom for
evacuation of dirt and condensation. Each tank has its own electric fuel pump.
Holding tank in acid resistant stainless steel installed in engine room. Manual
pump in the toilet compartment for drainage via through hull fitting. Connected
to deck fitting for evacuation ashore. All hoses to the tank are gas tight.
Volume of tanks
Fuel capacity: 1.190 liter in 4 stainless steel tanks
Fuel Dickinson heater: 120 liter
