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. We have published it on Youtube so everyone can see it.

James Wharram’s vision for this new design:

At any one time there are always two or three design ideas floating around in my design consciousness. Social, political or personal events will bring a particular design to the forefront for a new launching (my staff call them my obsessions!)

Due to the present tight financial situation a large number of would-be sailors are having a hard time financing their dream sailing boat. You can buy good small second hand boats at a reasonable price, but the problem is where do you keep them? All over Europe high marina/mooring costs make it impossible for many would-be sailors to own a boat.

The most economical way to enjoy sailing is to build your own small lightweight boat, to keep it at home and trail it to the waters you want to sail in. This gives opportunity to explore many more sailing areas than if based on a permanent mooring and at much lower cost.

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.

Don’s collection of severe weather experiences on Wharram Catamarans is now available to read online. It is a work in progress and more anecdotes will be added over time. Go and read it now, and come back in the future to see what’s new.

If you have experienced severe weather on a Wharram Catamaran, we would like to hear your story. Please contact us.

The ideal low budget self build ocean cruiser.

With a sleeping capacity of 6 (two doubles in the hulls) and spacious level deck area, TIKI 30 makes an excellent low cost charter boat.

It is our largest self-build boat design that is capable of being towed behind a vehicle. This means keeping the build weight down, and simple but adequate accommodation. This is not a high cost, luxury boat, but an elegant, versatile, 'double canoe' sailing boat, providing basic comfort for 'Living on the Sea'.

The Tiki 21 was designed in 1981 as an easy to build Coastal Trek catamaran, using new epoxy/glass stitch & glue techniques. In 1982 the new and then quite radical Tiki 21 was given first prize by Cruising World magazine (USA) in their design competition for a ‘Trailable Gunkholer’. Since then, 925 Tiki 21 Plans have been sold (June 2010).

In 1991-97 Rory McDougall sailed his self-built Tiki 21 'Cooking Fat' around the world, sometimes alone, sometimes with a companion. She was, and still is, the smallest catamaran to have circumnavigated. In 2010 Rory entered 'Cooking Fat' in the Jester Challenge (single handed 'race' across the Atlantic for small boats - under 30ft) and came into Newport, Rhode Island a close second after 34 days.

The Tiki 21 has stayed popular as a simple, easy to trail Coastal Trekker all over the world. Her unique soft Wharram Wingsail Rig has been used on all subsequent Tiki and other Wharram designs (30ft - 65ft) and is very popular with the owners of these boats.
