The Storebro Royal Cruiser 470 was the top model of the new design line that started with the SRC 340 Biscay. The layout of the ship was based on the layout of the 1985/86 presented SRC 52. Also, from the SRC 52 draft the SRC 470 inherited the flybridge.
DesignThe SRC 470 continued the SRC 340 design. In particular the narrow side windows stretched the voluminous ship and made it very elegant. Visually, the front view of the SRC 470 is reminiscent of the Royal Cruiser 47, which likewise had three single front windows. Originally the ship was projected as SRC 44. Compared to the original SRC 44 design, the radar arch of the SRC 470 moved to the aft edge of the flybridge. The first brochure of 1998 shows a drawing of the ship with a rounded side window of the deckhouse. This feature was never used with the SRC 470, but only with the sister model SRC 500 within the scope of a smaller facelift, from about 1992 onwards. This is similar to the air inlet of the engine room. This design was realized in 1997 for the first time with the SRC 430 Biscay and the SRC 430 Baltic and later in 2001 also with the SRC 515.
LayoutThe SRC 470 offered a three-cabin layout, although there was still room for the typical Storebro dinette opposite the Pentry. The berth in the underfloor cabin was correspondingly more cramped. The toilet room provided for the guests was generously dimensioned. The original layout envisaged a circular sofa instead of the U-shaped dinette opposite the pentry. During the detailed development phase, however, it turned out that the shape of the hull did not allow for this layout.
The deck saloon offered a large U-shaped sofa and at the same time a fixed driver's and navigator's bench seat. Conversion measures prior to departure were therefore unnecessary. This solution was only made possible during the project planning phase by increasing the length from 44 to 47 feet.
The layout of the owner's cabin corresponded to that of the SRC 40.
Engines
The first brochure from 1988 lists the Volvo Penta TAMD 71A (263kW/357hp) as standard engine. This was then installed in the first four ships. The fifth ship was the only one with the Volvo Penta TAMD 121D (310kW/422hp), but these were changed three years later against TAMD 122D. From 1989, the Volvo Penta TAMD 122D was fitted as the standard engine.
The effort to accommodate the TAMD 122D instead of the originally planned TAMD 71A in the engine compartment was considerable. Extensive investigations concerning the dimensions were required from both the shipyard and Volvo Penta.
Various changes were made, particularly after the prototype was built. This concerned, for example, the layout of the side windows and the inclination of the aft railing supports.
With the 1989 model year, the shipyard changed the windows to new aluminium frames. The previously angled profile was replaced with a flat profile. This measure was carried out at the same time on the SRC 340 and SRC 400.
Further measures can be found in the "Technical development" section.
MiscellaneousAt least five SRC 470s were retrofitted with a new stern using the original SRC 500 (or even SRC 515) attachment. These ships are now often offered as SRC 500. Only the view in the delivery lists reveals the actual type of the ship.
