The Insark Marine 45 is a semi-displacement, long-range motor yacht designed by Du Toit Yacht Design in close collaboration with Insark Marine. Built in aluminium and classified to CE Category A for ocean service, this robust vessel was conceived as a true go-anywhere cruiser, combining seakeeping, autonomy, and onboard comfort.
Commissioned by experienced yachtsman and builder Krasni Sutic, Beleza—the first Insark Marine 45—was custom-built to suit extended cruising in the Mediterranean, particularly along the Croatian coast. Designed to be operated by a couple, the yacht prioritises simplicity, safety, and smart ergonomics throughout.
At 45 feet, the Insark Marine 45 offers a surprisingly generous interior volume. Below deck, three comfortable double cabins (including a master suite with queen bed and en-suite) and two bathrooms provide a spacious and private accommodation layout. Above, the open-plan upper deck houses the helm, saloon, and L-shaped galley—blending function and sociability with 360° views and direct access to the side decks.
The hull form was developed for efficient passage-making at 8–10 knots, with a clean entry, moderate flare, and broad aft sections for improved stability and fuel economy. The full-length keel aids directional tracking and protects the running gear, including twin five-blade propellers in protected tunnels and a large rudder for added control. Power is provided by twin John Deere 300HP engines, enabling transoceanic range at low consumption. Fuel efficiency reaches as low as 1.5 litres per nautical mile, offering nearly 2,700 nm of range.
Notable features include:
- Aluminium construction for strength, safety, and longevity
- Wheelhouse with vertical windows for visibility and solar control
- Secure aft deck and all-round bulwarks for safe offshore movement
- Solid teak finishes and maple interiors for a warm, refined aesthetic
-
Integrated systems for owner-operator simplicity, including bow thruster, electric davit crane, central vacuum system, and advanced power management
The Insark Marine 45 delivers the rugged reliability of an expedition yacht with the gracious proportions and livability of a larger vessel. For those seeking a capable, elegant long-range motor yacht under 50 feet, it offers a rare combination of performance, practicality, and design integrity.
