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 Tahiti Wayfarer hull shape is derived from traditional dug-out canoes from Tahiti and Samoa, but built in stitch & glue ply/epoxy. All other components of the boat are constructed from materials found in nature. Crossbeams and spars are made from small trees and saplings with natural forks for jaws, stripped of bark and sculpturally finished, all parts are lashed together.

As she is likely to be used in the open sea she has a self-draining floor (large enough to sleep on) and watertight bow and stern compartments. This hull shape has only 8″ – 20cm draft; her lateral resistance comes from a fine forefoot combined with the area of the steering-paddle/side-rudder.

She can be built as a Double Canoe with two same-sized hulls and a platform big enough to erect a two man tent on, or as an Outrigger Canoe using just one hull and a light weight log as outrigger float. She is rigged with a crab claw sail, using rope standing rigging. Tahiti Wayfarer with her very shallow draft is a perfect boat for exploring, a great boat for use by scouts and youth groups or to be taken on a ‘Raid’. Auxiliary propulsion is by paddle, oars or Yuloh.

By self-making everything: natural spars, sails and even hand carved deadeye blocks, her building cost is very low (the Plans give all details). This is a boat that needs NO hardware! The aim of the Wharram new Ethnic Design range is to study and understand by practical experience aspects of the design of canoe form craft from the ancient sailing world.
