CONSTRUCTION
HULL
WASA YACHTS has designed a special moulding technique, unique in boat construction, which allows us to mold the hull in one piece.
To achieve a first rate product, WASA YACHTS is using a special selected polyester with supreme test result regarding:
- Stretch/break factor
- Pliability ratio factor
- Water saturation factor
- Adhesive factor
- Strength factor
- Material fatigue
- Polyester density
All these factors are very important in combination with the environmentally controlled moulding area. During the molding process it is very important to keep temperature and humidity at a predetermined controlled level.
The hull is made in GRP sandwich construction, using end grain balsa core and fibre-glass mats of different specifications.
All stress areas are specially strengthened with unidirectional rowing reinforcement in the direction of the stress. All through hull fittings are in solid GRP. Structural bulkheads are of marine grade waterproof plywood, laminated to hull and deck.
Transverse floor beams and longitudinal stringers are built up of GRP, unidirectional rowing using a high density core. There are limber holes in the floors to allow drainage.
Specially designed KEVLAR combination mat,in hull and deck (option)
DECK
The deck is made in GRP balsa core sandwich construction. All high stress areas are specially reenforced with selected material using the same technique as in the hull.
The deck has a high strength / weight ratio and is through-bolted with stainless steel (AISI 316) to the hull. The mountings for the deck fittings and have been extra reinforced.
BALLAST
A new keel shape has been developed based on extensive tank testing and practical test on ONE-OFF WASA Racing yachts.
The keel shape has the following advantages in comparison with an conventional keel:
- Higher lift - drag ratio.
- Lower centre gravity, increasing stability without adding ballast weight.
- Shorter cord length at top and tip, improving laminar flow and lower drag.
- The increased stability gives better performance and seaworthiness.
The fin keel, casted to high accuracy in lead with added antimony. The keel is through bolted to the hull with 6 cast in stainless steel keel bolts, (1 1/4" x approx 2' AISI 329).
RUDDER
The cantilevered balanced spade rudder is made of GRP filled with high density foam. The 60 mm solid stainless steel shaft (Special ordered Swedish stainless steel with three times tensile strength of AISI 316) passes through a low friction, non water absorbent bearing, mounted and strongly bonded to the hull.
The rudder was originally developed for our racing yachts, design the Swedish Royal Technical Institute. It has an impact zone, with external forces above 2 tons, the lower part of the rudder
will give away, still possible to navigate the yacht.
ENGINE BED
Originally designed by VOLVO PENTA is incorporated into the hull.
Special care is taken to ensure a rigid foundation and correct bonding.
