| These were of course excellent conditions in which to review the sea-keeping abilities of this latest Sports Cruiser. For those familiar with Redbay Boats you will know that these boats are always built based upon an uncompromising deep 'V' hull, no airy fairy stepped hulls here, and they are robust just like the proverbial brick outhouse. This new Sports Cruiser is built to the same formula. You can see the Cushendall works and learn how Redbay do the construction from our article 'behind the brochure'. Hard Nosed Four jockey seats and a full beam rear bench seat provide seating for up to seven on board. The deck space between the jockey seats and the rear bench seating is generous and would permit the fitting of a table quite easily. The jockey seat pods provide good storage areas. They did however require the seat cushions clipping down as they tended to move about when driving the RIB hard. My preference however would be for the cushions to be cut out forward to make standing up more comfortable and the addition of the latest 'winged' backrests which are now appearing on many new RIB models. The rear bench seating was very good on top of a huge rear locker, although I must say that access to the locker space was somewhat disappointing. The current design limits the locker opening to just some 12-16" which means you have to be on hands and knees to access the space. Within the rear locker is a single battery and isolator switch, my preference here would be for a twin battery installation. The freeboard was quite high with 21” diameter tubes and a moulded GRP deck on top. Indeed access from water level would require the use of a step ladder to get onboard. |

The Cuddy Cabin Storage space inside the cabin is remarkable. Five lockers/stowage areas comprising a bow and port & starboard deck lockers, plus two further open bow storage compartments. Enough space for almost everything including the proverbial kitchen sink. With a slightly larger cabin area though, provision for a small heads and hand wash basin would be possible. How Did She Perform? On 16 miles or so crossing in a gale force 8 three growlers caught us out on the port beam. Large beam seas are always one of the most difficult to tackle, but on each occasion the hull and tubes responded well as we were pushed sideways and tilted by the side swipe from the wave. The RIB responded quickly and was easily brought head to sea and back into control. One technique is to ride the top of a wave surfing along the crest until it's safe to drop off it and then to pick-up another. It's remarkable what speed can be made with an exhilarating ride at the same time! In quieter waters the max speed, with two crew and a full fuel tank, was virtually on the 40 kt mark at almost full throttle. The engine revs and stainless steel prop had been matched up very well indeed. Tight high speed turns to port & starboard proved the stability and the grip of the hull was exceptional. No slip or skidding even as the power was increased. A very good hull performance and a craft of exceptional sea-keeping ability. |

Bring On The Power The DF250hp has 3614cc displacement and 69hp per litre power to displacement ratio, the greatest ever seen in the 4-stroke category. The DF250 is also the lightest and most compact outboard in its class and a winner of the prestigious NMMA (National Marine Manufacturers Association) Innovation Award, a genuine custom built marine 4-stroke. It is based on a new 55-degree V6 configuration giving a slim more compact design; has a dual overhead cam 24-valve power head; electronic fuel injection; a tuned multi stage intake manifold to enhance engine performance by changing the way the engine breathes at different speeds; variable valve timing (Suzuki exclusive) which continually adjusts intake timing for more low and mid range torque, improved fuel efficiency and reduced emissions; offset drive shaft providing a big 2.26:1 gear ratio giving fast acceleration and top speed. There was no hesitation in getting the boat on to the plane and the throttle response was found to be very quick as proved in the challenging seas we encountered. The 250hp unit was an unbelievably quiet running outboard. One had to continually check the cooling water 'tell tale' and the engine rev counter to confirm that the outboard was still running. Yes, it really was that quiet! The overall weight of the boat is 2050kg plus fuel. The fuel tank holds 70 gallons (320kg) and with the DF 250hp gives a range of approx 300 miles. |
