Manufacturer Info



  Established in 1972, Sealine is all about the design and production of GRP power cruisers for the recreational market - and the key design intent behind its craft has always been to use every spare inch of space as usefully as possible. From its first boat, the 23 Continental, the company’s focus however has shifted up in size. The current range comprises eight craft across three main product lines ranging in length from 38 to 60 feet. It starts with the S380, one of two S Series Sports Cruisers. Next comes the F Series with three Flybridge Cruisers in hull lengths of 38, 45 and 49 feet. The single 49-foot ‘C’ Series Cruiser shares the same underpinnings as the new F490 but as a non-fly, it is more commonly considered among the S Series boats. And finally, at the pinnacle of the Sealine range comes the Yacht Series, with two traditionally styled luxury craft in lengths of either 50 or 60 feet.

Boat Description

The S450 is a bold and innovative new design offering more social space than on any other cruiser of this size.  The craft features a unique full length, soft top convertible roof system and large opening side windows which let in the light and the fresh air.

One of the most significant design features of the S450 is the cockpit layout which makes maximum use of the full beam width of the boat for seating and entertaining. There are four wide forward facing seats at the helm, a fully integrated dashboard, plus a wet bar behind the seats. To the rear the flexible seating and dining arrangement offers comfortable dining for 8. This space can easily be transformed into rear or forward facing sunbathing areas with optional hi lo private bathing platform.  

The luxurious forward master cabin will have separate shower and toilet compartments, whilst the three berth mid cabin offers five different sleeping options plus an ensuite shower and head. The saloon has space for 5 to dine in comfort.

There is ample storage throughout the boat. Engine options include Stern Drive or Full IPS.
