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.

The Mana 24 design does not have a study plan, comprehensive design information is available on our site.

Item Details: 

Based on the 1960s TANE design with more beam and higher freeboard, she can be built in foam/GRP sandwich or in plywood.

The Classic hull seaworthiness of the TANE encouraged many people to make ocean passages on her. We designed the TANENUI in 1973 to give these people on a low budget a sturdy, seaworthy basic boat with just that bit more internal space than the Spartan TANE.

By popular demand, we later drew her for building in the standard Classic plywood construction.
