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. This book reviews each self-build boat model and offers a detailed introduction and understanding of the world of self-build catamarans.
  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. You can build a Wharram with very little experience. Our Building Plans present quality instruction, guidance and advice for both novice and professional alike. A Wharram can be built in 130 hours - or you can indulge four years of your life into one.

HUI Wharram 2016 - Event Details

Well, it’s getting closer to May 20 - The big day for our annual Hui Wharram. I have refrained from sending too many emails; however, I would like to remind everyone that it really helps to have an attendance count to better prepare. The Web page on Facebook does work, but due to my ‘tech’ deficiencies it is a bit clunky. Maybe some of our Wharram communities members could help establish a simpler means to collaborate in the future.

So far: I have had indications that there will,be a number of Wharrams, and perhaps a few other multihull designs present. Pahi 31, Nari Mk V, Tiki 31, Tiki 21, (2 or maybe 3), Tangarhoa (?), and hopefully others. (if you can bring your boat(s).

Sixty years since trans-Atlantic trip

Sixty years since trans-Atlantic trip

On 27th September it will be 60 years since James Wharram, with Ruth and Jutta set sail from Falmouth on 23'6" Tangaroa, to become the first people to sail a multihull both ways across the Atlantic. The "Falmouth Packet' newspaper has been the first to publish an excellent article about this important event in the history of multihulls.

Spirit of Gaia renovation (Part 6)

James is proud of what has been achieved.

Another year and still more work. We have had to face up to the fact that the renovation of our flagship Spirit of Gaia is taking much longer than originally planned, but at last the end is in sight. We are aiming for perfection.

Oceanswatch to aid Cyclone Pam survivors


OceanWatch, a small and robust New Zealand NGO, will soon head to the Solomon islands to give aid in the ongoing aftermath of Cyclone Pam. Two Tama Moana designs were donated to the islands following the Lapita Voyage in 2008, and their work will include the repair of one of these that sustained damage during the storm.

More information can be found here:

Hanneke Boon at Pecha Kucha in Amsterdam

We have had a long friendship with Carl Cramer, publisher for 25 years of the American ‘Wooden Boat’ and ‘Professional Boatbuilder’ magazines. Last year Carl retired as publisher, but is continuing with other boat related enterprises. Last month he organized a Symposium on yachting in Amsterdam, called ‘Boatbuilding Live’ held on 17th November, the day before the opening of ‘Mets’, the European marine trade show.

James and Hanneke were invited to speak at ‘Boatbuilding Live’ in a 90 minute time slot, so got to work on writing a paper with the title ‘Integrating Philosophy with Boat design’. Unfortunately the symposium was cancelled, but instead Carl asked them to speak at a Pecha Kucha event, also in Amsterdam. This is a new lecture concept originating in Japan where every speaker can show 20 slides to which he/she can talk for 20 seconds each, i.e. a total of 6 minutes 40 seconds presentation.

We had to make a fresh start, for writing for a Pecha Kucha is more like writing poetry than a lecture. From a wordy concept to the minimum, so we saw the time slot of 6 minutes as an illustrated poem of Hanneke, from a young girl sailing with her father, ending up as a boatbuilder, ocean sailor and designer.

Storm Tactics on Wharram Catamarans

Wharram Cat on stormy seas

Wharram catamarans are well known for their seaworthiness and hundreds have been cruising the oceans of the World for nearly 50 years. As can be expected, many encountered storms during their voyaging, some were unlucky enough to encounter very severe ones and even cyclones and hurricanes.

Don Brazier, Wharram agent in New Zealand and owner/builder of a beautiful 41 foot Narai Mk IV, has been collecting accounts from many Wharram sailors who have experienced severe weather at sea. He himself has made a number of voyages in the Pacific and encountered severe weather, in which he deployed drogue and parachute.
