As part of the detail development, however, it turned out that the hull shape did not allow this layout. The original layout provided a circular sofa instead of the U-Dinette. 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. This is similar to the air inlet of the engine room. 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. The first brochure of 1998 shows a drawing of the ship with a rounded side window of the deckhouse. Compared to the original SRC 44 design, the radar arch of the SRC 470 moved to the aft edge of the flybridge. Originally the ship was projected as SRC 44. Visually, the front view of the SRC 470 is reminiscent of the Royal Cruiser 47, which likewise had three single front windows. In particular the narrow side windows stretched the voluminous ship and made it very elegant. The SRC 470 continued the SRC 340 design. Also, from the SRC 52 draft the SRC 470 inherited the flybridge. The layout of the ship was based on the layout of the 1985/86 presented SRC 52.

Built into the EDC system is an engine monitoring capability which alerts the operator in the event of a malfunction.The Storebro Royal Cruiser 470 was the top model of the new design line that started with the SRC 340 Biscay. Conventional push-pull control cables are eliminated by a fully electronic gear shift and throttle remote control. Improved engine acceleration, lower and more stable idling and lower smoke and exhaust emissions are some of the benefits claimed by the system. It uses a mechanical fuel injection pump that is electronically regulated, reacting to various parameters fed from sensors. Volvo's EDC, Electronic Diesel Control system was introduced in 1996, and was specially developed as a marine system. Its weight to power ratio of 2.98 kg/kW places it as one of the heavier engines in its class as shown in fig 1.

This rating includes light planing vessels in commercial use, patrol and rescue craft. Now an electronic regulated model has been introduced as the TAMD 122P EDC with a Special Light Duty Commercial rating of 455 kW (618 PS) at 2,250. The TAMD 122 engine with standard fuel injection pump has been around for several years, and last year an uprated TAMD 122P version developing 441 kW (600 PS) at 2,250 rpm was announced. Bore and stroke are 130 x 150 mm and uses a in-line six cylinder configuration, giving a total displacement of 12 ltrs. The four stroke direct injected diesel engine is turbocharged and intercooled. Volvo Penta are introducing for model year 1997 a new electronic regulated model in the 450 kW class designated TAMD 122P EDC.
