Catamarans and Trimarans

Catamaran and Trimaran Boat Plans make it a reality to build your own catamaran or trimaran. Multi-hulled sailing vessels are a special class of boat. A very different mind set is required when thinking about sailing a multi hull, let alone getting your head around building one.

There are some unique challenges building a multi-hull sail boat, the extra beam added by each hull for instance can create storage issues while under construction. Hartley boat plans make the build process straight forward for even amateur builders. However with all things considered, building a multi can be an amazing journey.

CRUISING NEWS

Never too young to enjoy a nice sunset.

Then and now

The seafront of Cartagena in Colombia is the backdrop for two sailing vessels of different epochs and sharply contrasting character.

Against the sea wall  Galeon Bucanero , a replica of a Spanish galleon of the seventeenth century is totally at home against the fortifications of this historically significant Spanish port city.

In the foreground Chincogan 52  Sole currently circumnavigating the globe stops over en route to Panama and the Society Islands.

Over the years I've received many wonderful photos of our boats from around the world. This one is an absolute classic. Many thanks to Mike and Sarah Mason for the shot.

Study Plans

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.

The Wharram Design Book reviews each self-build boat model and offers a detailed introduction and understanding of the world of self-build catamarans. Also available is James’ signature book, ‘Two Girls, Two Catamarans’, and his latest book, ‘People of the Sea’, in addition to a selection of books by other seafaring authors.

Films on DVD about adventures made on Wharram catamarans, building documentaries, and marine archaeology.

Merchandise

Merchandise of all things Wharram – T-shirts, customisable crew T-shirts, tank tops, pendants, mugs, hats, decals.

Papers and Articles

Technical articles about Wharram boats and their ascendants, philosophical and archaeological articles about seagoing communities, stone age sailors and pacific migrations. Adventure story collections by Ruth Wharram.

Limited Edition

To celebrate the 60th anniversary of James’ pioneering voyage west across across the Atlantic on Rongo, the first catamaran to do so, we are reprinting the original Building Plans of this design, which come in a presentation box-set including a photo book, stories of further voyages, plus a signed copy of James’ book ‘Two Girls Two Catamarans’.
