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 delivery costs, which is particularly beneficial for international customers. They can also be printed if you wish.
The Mana 24 design does not have a study plan, comprehensive design information is available on our site.

Narai Mk I & II Study Plan
The Narai Mk I & II Study Plan is intended to help you decide if this design is for you.
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.
