Design No. 073 – 3.150m (10'4") gaff sailing dinghy

design 073
Design 73 is a really versatile sailing and rowing dinghy and is one of the most popular of our designs. To the best of our knowledge, over 40 of these boats have been built to date.
design 073

The standard design is for ply epoxy lapstrake construction which is very straightforward to build and produces a strong, stable and lightweight boat. The hull is built on four simple temporary moulds, set up on a jig base. When the hull skin is completed, these temporary moulds are removed, giving a clean interior.

Forward there is a bulkhead in way of the mast, with a small foredeck, through which the mast steps. As well as adding structural rigidity to the hull, this provides a watertight compartment forward.

The side-benches aft also provide two watertight compartments, which, together with the forward compartment, give the boat the necessary built-in permanent buoyancy to stay well afloat if flooded or capsized. They also contribute to the structural stiffness of the hull.

The boat is built using modern materials and WEST system (or similar) boat-building epoxies. The construction gives high structural strength and rigidity, with light weight. The boat can be clear finished (varnished) or she can be painted. In either case you will have a long-lasting low-maintenance structure, so you’ll spend you time having fun with the boat rather than maintaining it.

Plans for traditional clinker construction (pictured here – click images to enlarge) and cold-moulded construction on laminated frames are also included in the design package. The boat has also been built in cold-moulded frameless construction on a plug and plans for that can be made available upon request.

Read a very nice article in Watercraft magazine about the clinker-built "Anemone" (opens as a new PDF window).

The detailed and accurate plans together with true step-by-step building instructions carry builders, professional and non-professional alike, through the building process simply and easily. And for larger boats particularly, they allow a managed build to be carried out very successfully. Plans are fully dimensioned; no scaling or lofting is required. The plans and instructions are practical, clear and detailed, containing everything required to build and complete the vessel. Where CNC cutting files are included, or available, they can be sent directly to a CNC facility as required. Professional technical support throughout the build, is available by email, via the forum or by regular mail. More plan info

A couple of comments by 073 builders:

"The dinghy exceeded all my expectations.... and a real bonus to find her such an excellent rowboat ..." – Stephen Dobson.

"... she sails like a dream and is well seaworthy (launch day was blustery and lumpy at sea!)." – Peter Jady.
