Solid Foundations
The hull of Raja Laut was built of exceptionally hard and resistant timber (a type of ironwood known as Belian or Ulin). Belian is second to none in durability and solidity. 
The hull is exceedingly strong and watertight, all fastenings are '304' stainless.
A persistent emphasis on timber quality and symmetry of construction mean the hull lines provide for a smooth flow of water and great stability. In addition the midsection lines are taken from the famous Spray design, a design renowned as for its stability and suitability as an oceangoing cruiser. The calculations indicated a hull speed of 10.8 knots and this has been confirmed by trial runs. 
The stability calculations confirm that the fully rigged schooner will have a positive stability of 90 degrees.
The keel is construed of one continuous length of ironwood 30cm wide x 35cm high x 21.5m long, free of holes or defects.
The planking (ironwood) varies in thickness from 7cm for the bottom hull to 6cm at the turn of the bilge and 5cm for the topsides.
Longitudinal stringers run the whole length at 17 cm spacing, from keel to deck. The keelson is 20cm x 20cm, deck beams 10cm x 15cm.
The deck itself is built of 2 layers of hardwood, with a layer of 
fiberglass in between insuring water tightness, caulked and sealed with pitch.
The frames are from sawn branches of ironwood, selected to fit the curvature of the hull. They are construed of 2 pieces, each 15cm thick by 10 cm wide, bolted together with a minimum of 50 cm overlap where joined.
