Sport 420

The Sport 420 - Luxury redefined

The Highfield SPORT 420 combines the durability of a performance aluminum hull with high-end luxury features, making it the perfect medium sized RIB

The all new Highfield Sport 420 is similar but a big step up in size and power to the SP390. The perfect combination of luxury features and a dry riding heavy-duty aluminum hull mean the Sport 420 is the best of both worlds in a small tender RIB. The twenty-degree hull with welded lift strakes with the built-in fuel system located under the deck will take you through the roughest conditions and can be brought up on rocky beach with peace of mind, while the luxury diamond stitch cushions make for a comfortable day on the water. The deep rear seat and ergonomic console offer more leg room any other RIB its size and the console includes a tinted windscreen, grab rail and the optional carbon dash. The dash has room for a 7” chartplotter to help with navigation. The bow step is designed to be extra wide for easy boarding, using split double bow nav lights and folding cleats so no tripping hazards. There are four dry storage compartments including an extra deep rear seat area, and all include hydraulic pistons to hold up lids for easy stowing. Rated for 8 persons and 70hp, and incorporating a built in 10.5 gallon fuel system, the New Sport 420 has everything you need in a deluxe tender RIB.
