Wharram Shop

Wharram Study Plans are intended to provide more detail than is available in the Design Book. In particular, they will help you decide if a particular boat design is for you.

The most important part of the Study Plan is the Materials List, which will list the major boat building materials requirements so you can cost your project in your own area.

We feel sure that after studying these plans you will appreciate the quality and detail of the Building Plans, which, for the more recent designs, are more like a course in wooden boat building than just a plan set.

Digital Downloads of all our Study Plans are available. They are available in hard copy format or as a digital download. The downloads are instant access and have the benefit of eliminating costly postal charges for international customers.

The Classic Designs were the first range of Wharram catamarans, designed in the 1960s and 70s, based on the sea experience of James Wharram's pioneering ocean crossings. They are sturdy, very stable, but relatively basic in design. They are built using simple plywood construction over a backbone and bulkhead frame. The Building Plans for these designs are not as detailed as for the later designs, but as the construction is simple are still easy to follow.
