What is a lapstrake hull design?
Clinker built (also known as lapstrake) is a method of boat building where the edges of hull planks overlap each other originating in Scandinavia.
What is lapstrake planking?
Lapstrake planking refers to the method of attaching planks to the frames and to themselves. The planks actually “lap” one. edge over another as opposed to butting together at their edges as in standard batten-seam or straight-carvel construction.
What are the advantages of clinker construction?
Most believe carvel planking is stronger than clinker-built and therefore less flexible. However, clinker-built construction allows for some wiggle between the planks, making these boats more adaptable to wave and weather conditions.
What is clinker plywood?
CONSTRUCTING A CLINKER PLY (LAPSTRAKE) BOAT. Back to Boat Building Methods Main Page. INTRODUCTION. Clinker (or lapstrake) construction involves the planking of the hull with adjacent planks slightly overlapping one another (in a stepped fashion).
What kind of boat is a clinker?
Clinker built (or lapstrake) vessels are lighter as they have less internal framing – with the planks overlapping along their edges. As they’re lighter, they displace less water allowing them to move faster. Clinker vessels are less rigid than carvel constructions, limiting the type of sailing rigs the vessel can take.
What was the clinker technique?
Clinker or Lapstrake is a method of attaching planks to a boat where the plank edges overlap each other. Overlapping planks are then fastened to each other and then to the frames. This age old method of planking, sometimes referred to as clinker planking, has been in use for hundreds of years.

What is the lapstrake method of construction?
Construction Methods — Lapstrake or Clinker A description of the lapstrake, or clinker, method of boat construction Lapstrake/Clinker One of the very first boats I built as a teenager, was one using narrow overlapping solid-wood boards (attached with copper rivets and roves) and at the time it was called ‘clinker’ construction.
What boats have we made glued lapstrake kits for?
With the word having spread that we had successfully kitted the Oughtred designs, the phone started ringing with requests to kit other designers boats, so we have now made up glued lapstrake kits for Duck Trap’s Christmas Wherry and Duck Trap Wherry, the Whisstock 074, and Paul Fisher’s 9 & 15ft Northumbrian Cobles.
