This is a smaller version of the Avon 22 multi role boat for a client who wants a light easily transported boat for use around the coast of Anglesey which is efficient under outboard power but which will also show a clean pair of heels under sail. She can be easily adapted to take what ever rig you choose (the unstayed sprit boom rig is shown on the drawings) or she may be made purely for motoring. A small cuddy can be fitted and a centre or dagger board fitted instead of the leeboard (the leeboard acts in an external slot formed at the gunwale and chine). Construction like her sister is from simple pre-shaped ply panels using the stitch and tape method and 5 sheets of 6mm are required for the basic boat. LOD 12’; Beam 4’8’’; Draft 5’’/2’; Weight approx. 100 lbs. The drawings also include the panel shapes for a 14’ version.
Duncan Curtis, who suffers from MS, has used the Avon 12 hull as the basis for a boat that will take him safely sailing. His modifications and the rig he has used help him to control the boat and sail in shallow waters - look out for his description of the MOBI project in various magazine articles that will be published soon. Below are some photos of his modified Avon 12 taken by Suzanne Grala.
