From 14ft out-riggers up to 63ft community living spaces. Wharram designs fulfil your boat building dreams.

Building your own boat with Wharram Designs is the easiest and most cost effective way to fulfil your sailing dreams. Wharram Self-build boat plans start from only £145. 

We recommended you follow the tried and trusted Wharram process to ensure the boat you build is both the right type of boat for your needs and also one that will match your building skills and expenditure.

1. Read the Wharram Design Book and familiarise yourself with the various designs and their unique qualities.

2. Order one or more sets of our boat building study plans and immerse yourself into the boat builder's mindset; evaluate the costs; the amount of time required to build your boat; where you will build it and where you will eventually launch it.

3. Once you have decided on the boat that is right for YOU to build, order the boat builder's plans and become a real life member of the Wharram boat builder community.

Eric de Bisschop and James Wharram - Catamaran pioneers

One man above all has kept the memory and achievements of the French pioneer of modern catamarans, Eric de Bisschop, alive. This is James Wharram, who in 1944, at the age of 16 bought the English translation of Eric de Bisschop’s book ‘The voyage of the Kaimiloa’ (published in English in 1940).

The voyage of the KonTiki raft, in 1948, to prove the theory of the settlement of the Central Pacific islands from South America (East-to-West theory), achieved worldwide fame for Thor Heyerdahl.

In contrast, because of the post war political situation in France, Eric de Bisschop’s pioneering voyage from Hawaii to France on ‘Kaimiloa’ in 1937-39, proving the seaworthiness of the raft stable double canoe, was forgotten.

New opportunity to work with Hanneke Boon on Spirit of Gaia

Spirit of GaiaDue to Hanneke breaking her leg in March the work trip to Greece had to be postponed and will now take place during September 2012.

Hanneke will be taking Spirit of Gaia to Messolonghi Marina/boatyard (a new marina under Dutch management), just West of the Gulf of Corinth in Greece. She will be doing renovating work on her to make her again the ocean-going Wharram Flagship she should be. We are looking for anyone who would like to help with this work.

Pahi 63 Self-build Boat Plans

Wharram eyes logo

Pahi 63

The Pahi 63 is a tribal boat, suitable for expedition sailing and for larger groups of people to cruise or eco-charter.

The deck/accommodation layout resembles a village, with a central public area including ‘well’ and (optional) ‘hearth’, surrounded by private cabins. This centre deck and the separate aft and fore deck areas give three large emotionally different spaces, enabling people to have hours in seeming solitude.
Length Overall:
63'
19.20 m
Beam Overall:
28'
8.53 m
Waterline Length:
51'
 15.5m
Draft:
3' - 5'
 0.9m - 1.5m
Weight:
   8 tons
Loading Capacity:   4.5 tons
Sail area: 1400sqft 130sqm
Building time estimate: 4000 hours  



This deck layout combined with the 'Flexi Space' hull cabins (all with their own entrance) enables 8-10 people to live peacefully together for weeks at a time.

The Pahi 63, based on traditional Polynesian double canoe principles, is most suitable for use in warmer climates.
