The first tug could be completed within 2 years , the second one within 29 months. In September 1951 was the discussion still not ended. The price for a 1.800bhp tug was ƒ3.195.000 each, of which 50% was fixed. The first tug could be delivered end 1953, the second one early 1954. Earlier in May was calculated that the costs for a hull included 20%profit were ƒ 1.500.270,0, 15% more compared with 1950.
Dimensions 51,00 (between perpendiculars)-57,60 (over all) x 9,30 (on waterline)-9,50 (moulded) x 5,40 (moulded depth) x 4,40 (mean draught in sea water with 260 tons deadweight) metres. Camber of the main deck 1,9cm. Deadweight with maximum loaded 260 tons of 1.000 kilo included 200 tons fuel oil, 30 tons fresh water (excluded spare water tank), 8 tons lubricating oil, 12 tons for provisions and crew and 10 tons equipment delivered by owner. Trial speed in loaded condition with a deadweight of 260 tons was to be 14-14,5 knots in smooth water and maximum Beaufort 3 wind force. Horsepower at this speed was to be 1.800bhp at 225 rpm and a mean draught of 4,40 metres. Bollard pull with a speed of 5 knots at least 13 tons of 1.000 kilo. The fuel oil bunker capacity was with an economic speed of 12 knots to be sufficient for a range of 12.000 miles. The horsepower could vary between 1.800, 2.400T and even 3.300 bhp. The hull had to have a soft nose and a cruiser type shaped stern and was with 8 watertight/oil tight bulkheads divided into 8 compartments. The tugs were however never built.
