Details and Specifications of Reef Inspector

Our Sea Cat Ships team have been busy at work on our latest custom design and construction project, our 22.3 metre (SeaCat 74’) long-range cruising catamaran ‘Reef Inspector’. This ‘state of the art’ high-performance catamaran launched at Ocean Marina Yacht Club in June 2022.

This expedition catamaran is ideal for luxury offshore cruising and is also suited for VIP day and overnight charter operations. She is fitted out for scuba and snorkeling trips out to the Great Barrier Reef with a dive compressor and scuba gear thus the name ‘Reef Inspector’.

This version features three levels of comfort: The main deck has three VIP cabins all with king double beds and ensuites, a lounge area which converts to a four berth cabin plus a large custom built aluminiun galley and a dining area. The aft’ main dive deck has a large outdoor entertainment/dining area with dive bottle storage, davit and dive tender.

On the upper deck there are walk-around sides with large forward area, featuring a jacuzzi pool which converts to a large day bed and aft’ decks that have a seating area for alfresco dining. The helm position is situated forward with lounge area/two double berths aft of this. The sunroof has an outdoor control station and area for both deck chairs and solar panels. All internal spaces are fully air-conditioned. The exterior finish is fully faired and painted professionally to give that sleek “Motor Yachtt” look.

Powered by twin Volvo diesel marine engines (2 x 800 h.p.) and IPS 1050 drives her sprint speed is around 30 Knots with an economical long range cruising speed of 10 knots with total fuel consumption of only 46 litres per hour. Large fuel capacity matched with fuel efficient hulls give extended range of over 3000 Nautical Miles. This slightly raked bow (to maximize the waterline length) Sea Speed design is based on a proven hull and high-performance vessel. She is very fuel efficient, cutting though the water with a great sea keeping and low wake motion. The Sea Cat designed slightly raked bow (to maximize the waterline length) ensures a high-performance hull and vessel.

The vessel has been built in accordance with Australian commercial vessel standards 1C (80 passengers plus 5 crew) and Class 2B for 12 Passengers plus 4 crew (Overnight) criteria with hull and deckhouse to Lloyds Register SSC standard for offshore operations.

This model can be custom designed to suit a broad range of customer requirements. Sea Cat is looking at diversifying into the Motor Yacht market building aluminium catamarans based on their range of proven hulls up to 42Metres (135 ft).
