Storebro Royal Cruiser 465 Biscay

Information

The Storebro 465 Biscay was one of the new models developed within the Nimbus Group from 2000. Although the shape was reminiscent of the SRC 430 Biscay and the SRC 465 Biscay also took over the flybridge from the SRC 430 Biscay, the ship was to a large extent a new development. The design was strongly oriented on the previous Nimbus design line. After 11 boats had been produced, production was discontinued in favour of the successor model, the SRC 475 Commander.

Compared to the SRC 430 Biscay, the side windows were cut narrower and the stairway to the flybridge was now a fixed staircase. These stairs at the same time reduced the width of the aft sliding door and so took the inside of the ship quite a bit of light.

Although the hull resembled in its design the SRC 420/430, it had a completely different propeller/rudder design. The long propeller shafts associated with a small angle of inclination reached almost up to the transom. The rudders were stern-mounted. The exhaust pipes no longer ended under water at the transom but now on aft side of the hull.

Overall, with the construction of the ship it was a development of an exceptionally quiet ship.

Unlike its predecessor, the SRC 430 Biscay, only Volvo Penta engines were used. The previously used Scania DI9s were no longer used. Compared to the Scania engines, the Volvo Penta TAMD74 engines were about 50 kg lighter. With 353 kW/480 hp at the crankshaft, TAMD74 were only marginally less powerful than the Scania DI9 with 355 kW/483 hp. The modified hull with flatter angled shafts, however, ensured a top speed that was about 2.5 kn higher.

All ships were equipped with the ZF IRM 280A intended for the Volvo Penta TAMD74. However, after the first ship, which was equipped with a gear ratio of 1.48:1, the other ships were equipped with a gear ratio of 1.77:1.

What is striking about this ship is the large number of combinations of shaft diameters and cones. While the first ships were delivered with a shaft diameter of 50 mm, the diameter was later reduced to 45 mm. The standard 1:10 cone used until then also changed to 1:16, with both 50 mm shafts with a 1:16 cone and 45 mm shafts with a 1:16 cone.
