Innovations are at the core of Marell, and our purpose and culture, where our ambition is to design and perfect the next generation high-speed interceptors.
We are proud of many of our unique innovations that will enhance our crafts further, in important areas like sustainability, performance and safety. Below we have included 10 examples of our unique innovations.
Signature center steering console
The center steering console is a unique Marell signature innovation across our M17, M15, M12 and M9 series. The center console enables optimum sight, most secure experience and highest comfort for the helmsman and crew during both boarding and sharp turns. The helmsman is always in full control with perfect sight along both sides of the vessel, independent of turning direction, heel, or speed. The position and height of the shock absorbing driver’s seat and the railings on fore deck are thoroughly lined out, to maintain an open view and sightline. All dashboards are designed to avoid reflection and are covered with black anti-reflex mats. Even smaller vessels like the M9 are equipped with three large screens creating an unrivalled center steering cock pit experience for optimized helmsman control, visibility, and safety.
Hybrid-ready and lightweight hulls
Marell has launched an effort with the aim to become the most renowned shipyard for high-speed interceptors in contributions to CO2 reductions. In order to achieve this, we have designed and created an industry unique hybrid-ready and lightweight hull for high-speed interceptors. The hulls are optimized for energy and emission savings and are therefore the perfect platform for hybrid and electric propulsion systems. The lightweight and strong hull, with a perfectly balanced dynamic lift, reduces hull friction and wave resistance across the whole speed range, which results in lowest possible energy consumption. The EV / hybrid engines, battery packs, fuel tanks and technology deployments are positioned in an innovative and a unique way, to keep the balance and secure low resistance of the craft across all speeds.
Hull design delivering low waves and high-speed
The Marell hull design has proven to stand out against competition as a main source of differentiation, through extensive testing and real-life experience in heavy seas. The negative angled chines and lifting strakes parallel to the keel line creates a dynamic lift which reduces hull resistance and gives higher speed and better grip in water during turns. The balance between the strakes and the deadrise assures no disturbing hump for the driver and minimizes the bow and stern waves at all speed. The sides of the hull are slanted to reduce dynamic wave friction and create a course stable hull also during sharp turns without any risk for chine tripping. The hull design leverages insight and experiences from winning offshore racing design and from high-speed aluminum law enforcements crafts.
Unique low and open aft deck design
The aft deck is formed as an easily accessible platform without obstructions, which makes the vessel suitable for special equipment, bulky cargo, and SAR operations. The air- and watertight access panels and doors to the engine and technical rooms support ease of maintenance and service. The air intakes to the engine room are inside the bulwark, positioned at aft wall of wheelhouse which secures the air flow without ingress of water spray and maximizes the aft deck space without any obstructions. The low platform can be used as storage and launch area for smaller RIBs and Watercrafts with rollers fitted to the aft gunwale, as the deck is open to the aft without bulwark. Due to the open design, the drainage of the aft deck will be instantly, no need for scuppers or other means of drainage.
Vacuum formed GRP roof design
The roof design and its integration to the rest of the vessel can also be innovated. We introduced and launched 2020 the first vacuum formed Glass Reinforced Plastic (GRP) roof with sliding hatch and glass roof, when we delivered the first M15 Patrol to the Stockholm Sea Police. This construction reduces weight and lower the vertical center of gravity of the craft. Moreover, it creates a craft that is lighter and more stable at sea in slow and high-speed operations. The tinted glass roof creates an open and light atmosphere in the wheelhouse together with the sliding roof. The roof is bonded and sealed to the wheelhouse framing leveraging industry leading bonding techniques.
Recessed bollards and railings
The sturdy design of the bollards and railings creates a secure sensation for the crew when walking on deck, boarding other vessels, or mooring the craft. From a safety perspective, this is in particularly important during cold and bad weather, when carrying large gloves and the crew is exposed to higher risks. All bollards and railings are all nicely recessed in narrow passages along the bulwark and wheelhouse cabin to avoid the risk of getting material or gear caught accidentally. All bollards and railings are made of the same aluminum material as the hull and they are welded to the hull and to the vessel superstructure, which forms a solid and durable construction that extends the vessel life length.
