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

Amatasi was designed for the 2010 Design Competition in Classic Boat magazine for a Fishing boat under 30ft/10m that would not need a licence for fishing under sail or oar. She won First Prize!

The design is modelled on the hullshape of fishing canoes of Samoa, but built in ply/epoxy/glass stitch & glue construction. Beams and spars are constructed from naturally grown roundwood (i.e. whole tree trunks). Hulls, beams and platform are all lashed together in Ethnic fashion. Running rigging uses hand carved dead-eye blocks. The Plans explain how to make all these components in detail.

The hulls of Amatasi can be open-topped and self-draining, or can be fitted with a lift-off cuddy (on one hull or on both hulls). The large planked platform between the hulls easily fits a standard camping tent to give extra sleeping accommodation for 2-3 people.

Amatasi has a Cat Yawl rig, with a gaff mainsail and small spritsail mizzen. Without a jib the standing rigging can be rope. The small mizzen is used for manoeuvring and tacking. She has Indonesian style side rudders.

By self-making almost everything, including natural spars and hand carved deadeye blocks, her building cost is low. This is a boat that needs NO expensive yachting hardware! If you are skilled at sewing you can even make the sails as well.

In 2011 we built the prototype, which we test sailed in Cornwall and in the Traditional Boat festivals in Brest and Douarnenez in 2012. She fulfilled all our expectations.

Amatasi is an ideal boat for youth groups, Raids and Coastal Trekking.
