Nordkyn Design is presently the home of two featured marine design projects: the 13-metre (43′) alloy sloop Nordkyn and the 11.2-metre (37′) cruising launch Wild South.

Both these projects embed the key guiding concepts on this site:

  • Exceptional attention to hull design
  • Seaworthiness
  • Purpose
  • Efficiency
  • Simplicity

The sloop Nordkyn was designed as a high-performance offshore expedition cruising yacht, specifically with the intent of voyaging in remote latitudes. It is spacious, comfortable, extensively insulated and easily heated. It is light, strong, extremely resilient with multiple watertight bulkheads and phenomenal under sail.
The underlying philosophy is travelling far, staying and exploring there before finally getting back out.
It was a personal project and no effort or time were spared to obtain an exceptional result throughout design and construction.

The launch Wild South was designed for coastal cruising, going fishing and living aboard at the bottom end of New Zealand, a relatively cold, windy and rough part of the world. An accent was placed on effective usability: it is a boat that goes out a lot.
It is a boat to enjoy the voyage as much as the destination, a boat for spending time at sea with a huge steaming range and excellent fuel economy. It is not an expensive boat to build either.

Both vessels were designed to go to sea before anything else. They have been extremely successful.

Over time, those interested will also find here various resources related to the dynamics of small vessels at sea, seakeeping, efficiency and propulsion considerations for power craft, the dynamics of small craft in heavy weather, marine electrical engineering, construction in aluminium and foam core as well as other technical matters.

Besides projects such as above, Nordkyn Design operates as a design office and consultancy in the fields of:

  • New designs for series production and development of ranges for commercial boatbuilding firms
  • Development and optimisation of manufacturing processes and shop floor practices in aluminium boatbuilding
  • Refits and transformations of commercial crafts: design, planning and project management as required
  • Stability analysis and other requirements for commercial operation under survey
  • Hull optimisation and propulsion efficiency improvements

Electrical Design For a Marine Lithium Battery Bank

Electrical Design For a Marine Lithium Battery Bank

This article is part of a series dealing with building best-in-class lithium battery systems from bare cells, primarily for marine use, but a lot of this material finds relevance for low-voltage off-grid systems as well. Integrating a lithium battery bank on board a vessel introduces a few additional constraints and challenges that don’t exist with lead-acid […]

Assembling a Lithium Iron Phosphate Marine House Bank

This article is part of a series dealing with building best-in-class lithium battery systems from bare cells, primarily for marine use, but a lot of this material finds relevance for low-voltage off-grid systems as well. Here, we detail the hands-on process of building a lithium battery bank from individual single prismatic cells. There is more to […]

Practical Characteristics of Lithium Iron Phosphate Battery Cells

This article is part of a series dealing with building best-in-class lithium battery systems from bare cells, primarily for marine use, but a lot of this material finds relevance for low-voltage off-grid systems as well. Batteries are about voltage, current and capacity first and foremost. This article discusses the performance characteristics of lithium iron phosphate cells […]

From Lead-Acid to Lithium: New Battery Technology for Power on Board

This article is part of a series dealing with building best-in-class lithium battery systems from bare cells, primarily for marine use, but a lot of this material finds relevance for low-voltage off-grid systems as well. The development and mass-manufacturing in recent years of large-size lithium-ion battery cells for electric vehicles and grid-tied electricity storage has made […]

Heavy Weather Dynamics: Upwind Sailing, Windage and Resistance

Heavy Weather Dynamics: Upwind Sailing, Windage and Resistance

With tropical cruising becoming increasingly popular and accessible in the last 2-3 decades, trends have developed in outfitting yachts for ocean cruising. Some of these trends that originated from sailing in moderate settled weather areas have resulted in significantly increased risks when a vessel is caught in severe conditions. Many of today’s cruising yachts, whether […]

Collision Avoidance at Sea: AIS Alarm Project

Collision Avoidance at Sea: AIS Alarm Project

AIS, for Automated Identification System, is probably the most remarkable safety improvement in decades for small craft offshore. The little project presented here involved designing and building a simple, very low power alarm system to keep an AIS watch at sea. Collision Avoidance at Sea Avoiding undesirable encounters with ships in mid-ocean has always been a […]

LED Lighting on Board

LED Lighting on Board

One of the largest technological differences between fitting out the sloop Yarra in the early 1990s and launching the Nordkyn design in 2010 was the transition from halogen to LED lighting. The performance and quality of LED lights was evolving so rapidly that I literally deferred purchasing light fittings until the last moment.The following sums […]
