Unique self-build sailing catamarans, inspired by the double canoes of the Polynesians

Find the Right Boat for You

The Wharram Design Book is the best starting point if you are still exploring the full design range. It gives an overview of each self-build model, introduces the Wharram boat builder’s mindset, and helps you narrow down which boats may suit your needs, dreams and sailing plans. It is available as a digital download.

A Study Plan then takes you deeper into a particular design. With large plan sheets, design notes, photographs, performance information, article extracts, FAQs and a materials list to help estimate local building costs, it gives you a clearer sense of the boat before you move on to the full Boat Building Plans.

Study Plans are only available as digital downloads. You can print them at home if you wish.

The Mana 24 design does not have a Study Plan, comprehensive design information is freely available.

Description

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.
