Back to Vancouver Again
European 200cm X 160cm mattress on the bed and require only an additional 10cm total length for heads and master cabin. We now need to claim 80cm from the engineering spaces.
The SRF engineer, Wychard Raadsveld came and measured our engine room and machinery spaces to see how much room we could liberate by installing a smaller engine. Nieuwe Zorg currently has a six-cylinder Perkins, which is rated at 86 kW. Besides being nearly half a century old, the engine is much more powerful than the 50 or 60 kW that the skûtsje requires. A smaller engine will allow us to reduce the length of the machinery spaces and to lengthen the living spaces.
Wychard proposed the Perkins-Sabre M92B with a PRM 5000 gearbox. At the propeller shaft, it develops 50 kW at 1500 rpm and 62 kW at 2400 rpm. The engine is a normally aspirated, low revolution unit with its maximum torque of 320 Nm produced at 1400 rpm. At that speed, the fuel consumption is 4.5 litres per hour. With these specifications, it appears to be the ideal power unit for our 18.5 ton skûtsje.
The first step in determining the amount of living space we will have available is to plan the space required by the mechanical installations. Wychard took more measurements in the after spaces as he gathered information to begin designing the layout of the equipment. The engine and transmission, the fuel tanks, the generator, the battery banks, the isolation transformer, the inverter/ charger, the water heating and the central-heating systems all need to be laid-out in the most compact arrangement that is consistent with easy inspection and maintenance access.
On Tuesday the 9th we went up to the office to meet Wychard. He had offered to drive us to the train station so we could catch a train into Leeuwarden to pick-up a reserved car from Hertz. Wychard instead drove us the 25 kilometres to the Hertz office in Leeuwarden, offering the excuse that he had an errand in the area.
We got up at 0400 on Wednesday, packed the bedding, towels and the last bits of stuff into our luggage and drove the 325 kilometres to the airport in Brussels for our 1040 flight. We made the flight and then had a long wait in Montreal for the connection onward to Vancouver, where we arrived near midnight. Fortunately, our 69 kilograms of checked luggage didn't make the flight, and after an easy registration with the baggage agent, we walked our carry-on to the SkyTrain and to our loft without the huge encumbrance of heavy luggage. The wayward luggage was delivered to our door the following day.
We are back ashore in Vancouver, now with two boats. The nearer one is 4100 kilometres away, the further one is 7700 kilometres.
