What is Clinker Construction?

Clinker construction, also known as lapstrake, is a method of boat building where the edges of the hull planks overlap. This technique originated in Northern Europe and was notably used by the Vikings, Anglo-Saxons, Frisians, and Scandinavians. Klinker construction is characterized by its overlapping seams, contrasting with the seamless joints of carvel construction.

Key Features of Clinker Construction:

1. Overlapping Planks: In Clinker construction, the planks of the hull overlap each other, creating a strong and watertight structure.
2. Traditional Usage: Clinker-built boats have been used since ancient times and were particularly common during the Viking Age and the era of the Hanseatic League.
3. Distinctive Design: The overlapping planks give Clinker-built boats a characteristic appearance, which is distinguishable from other construction methods like carvel.

Construction Process:

1. Planking: Planks are laid with their edges overlapping, and copper rivets are used to secure them together.
2. Framework: Once the hull planking is assembled, cross beams and longitudinal members are added to strengthen the structure.
3. Fittings: Various fittings such as swivels, plates, keels, and bands are mounted on the boat’s hull to complete the construction.

Comparison with Carvel Construction:

Clinker construction differs from carvel construction in that it utilizes overlapping planks instead of flush seams. While carvel boats have a smoother surface, Clinker boats are known for their strength and resilience. Despite its perceived hydrodynamic disadvantages, Clinker construction offers advantages in terms of weight and flexibility, particularly in challenging sea conditions.

Conclusion:

Clinker construction, with its long history and distinctive design, remains a valuable technique in boat building, especially for small wooden vessels. Understanding the principles and techniques of Clinker construction provides insights into traditional maritime craftsmanship and the evolution of boat building technologies.

Although its a tiny bit commercial: I would recommend the 42 lessons for clinker plywood construction at the http://www.offcenterharbor.com website!
Its such a good way of learning from a professional builder in his very ‘slow’ teachings.
There are more courses on that site: among others there is building a strip plank way, lofting and even navigation as I recall ….

Thank you for that piece of information! These kinds of courses are not that easily found.
