Find the right boat for you
Wharram Study Plans are intended to help you decide if a particular boat design is for you. They provide more detail than is available in the Design Book. 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.
Study Plans are only available as digital downloads. Downloads are instant access and eliminate postage costs, which is particularly beneficial for international customers.

The Tiki 21 was designed in 1981 as an easy to build Coastal Trek catamaran, using new epoxy/glass stitch & glue techniques. In 1982 the new and then quite radical Tiki 21 was given first prize by Cruising World magazine (USA) in their design competition for a ‘Trailable Gunkholer’. Since then nearly 1000 Tiki 21 Plans have been sold (2015).
In 1991-97 Rory McDougall sailed his self-built Tiki 21 'Cooking Fat' around the world, sometimes alone, sometimes with a companion. She was, and still is, the smallest catamaran to have circumnavigated. In 2010 Rory entered 'Cooking Fat' in the Jester Challenge (single handed 'race' across the Atlantic for small boats - under 30ft) and came into Newport, Rhode Island a close second after 34 days.
The Tiki 21 has stayed popular as a simple, easy to trail Coastal Trekker all over the world. Her unique soft Wharram Wingsail Rig has been used on all subsequent Tiki and other Wharram designs (30ft - 65ft) and is very popular with the owners of these boats.
