HOLLD 74 carbon catamaran, architecture and technical choices for the open sea

On the horizon, some units announce their program from the outset. The HOLLD 74 is one of these catamarans, designed to last at sea. Between technical mastery and the art of living on board, it charts a course towards the open sea.

With the HOLLD 74, the shipyard offers a long-distance cruising catamaran designed for long crossings with a reduced crew, based on carbon construction and a technical approach focused on consistency at sea.

A monolithic carbon structure to enhance marine performance

The platform is based on a carbon fiber and epoxy resin construction produced by single-phase infusion. This method limits the need for secondary assemblies and greatly reduces the need for manual lamination.

On the water, this structural continuity provides a high level of rigidity. The catamaran retains its shape under load, which favors precise helming and sail trim. This rigidity also helps limit vibrations and deformations in choppy waters or when sailing downwind.

Weight management extended to the entire rim

The project is based on a discipline of mass applied to all levels, including the interior. The furniture, too, is made of carbon, enabling the overall displacement to be contained despite the volumes of a 74-footer.

This approach has a direct impact on cruising performance. A lighter boat accelerates more easily and maintains high average speeds without putting excessive strain on the rig or engine. In offshore sailing, this allows you to optimize passage times and fine-tune weather routes.

Design for reliability and long-distance navigation

The engineering of the HOLLD 74 is based on a logic of sustainability and constancy at sea. On-board systems are designed for continuous operation, with particular attention to redundancy.

This choice concerns both technical circuits and equipment essential to life on board. The aim is to limit interruptions during navigation and ensure continuity of service during long crossings. This organization meets the requirements of an ocean-going program with a limited crew.

Habitability structured around cruising life

With a beam of 10.20 m, the catamaran develops a large volume on the main deck. The saloon adopts an open layout, linking the galley, saloon and dining room in a single space. Glazed openings ensure visual continuity with the exterior and facilitate circulation.

The layout of the cabins clearly distinguishes between different uses. The port hull houses an owner's suite forward, complemented by an aft cabin for guests or crew. To starboard, an aft double cabin features a private lounge area, while another double cabin is located forward.

This layout is designed for a family program with accommodation capacity, while preserving separate areas for privacy on board.

Tailor-made solutions to marine constraints

Each unit has its own specific layout, developed in collaboration with designer Linda Chevallerau. The choice of materials, finishes and interior layout are all part of a personalized approach.

But this freedom is limited by the constraints of a carbon multihull. Respecting the centering of masses and longitudinal balance imposes limits on the choice of layout. Materials must also remain compatible with the structure to maintain the overall coherence of the boat.

A cruising catamaran built in Holland by Holld Yachts

The HOLLD 74 is designed for sailors engaged in long-distance cruising, with a focus on efficiency at sea. Here, average speed becomes a tool for managing distances and weather conditions.

Based in Zwartsluis in the Netherlands, Holld Yachts follows in the tradition of Dutch shipyards focused on technical precision and custom construction. The shipyard focuses on carbon units, with a mastery of composite processes designed to produce platforms that are both rigid and light, suitable for ocean cruising. The organization is based on a workshop approach, without mass production, where each boat is developed as a unique project in close collaboration with its owner. This approach enables us to explore complex shapes and advanced technical solutions, while maintaining overall consistency between architecture, construction and use at sea.
