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 NARAI design is a direct descendant of the 40ft RONGO on which James made his pioneering voyage across the North Atlantic in 1959. NARAIs have been rigged as junks, Polynesian sprits, Bermudan ketch, Bermudan cutter or gaff schooners – powered by deck mounted diesels or outboard engines, the NARAIs attract the pioneering type. Now also available with the Wharram Wingsail rig (extra package).

The Mk I is the basic design. The Mk II has an extended centre cabin, giving more accommodation space. Drawings for both included.
