Amatasi 27 Study Plan (Digital Download)

Find the right boat for you

Wharram Study Plans are intended to provide more detail than is available in the Design Book. In particular, they will help you decide if a particular boat design is for you.

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.

We feel sure that after studying these plans you will appreciate the quality and detail of the Building Plans, which, for the more recent designs, are more like a course in wooden boat building than just a plan set.

Study Plans are available as a Hard Copy or Digital Download. Downloads are instant access and eliminate postage costs, which is particularly beneficial for international customers. Digital download customers will receive an email with download instructions upon checkout completion.

Hard Copy Study Plans are being phased out and will no longer be available after stock has sold out, at which point they will be digital only. Get your hard copies while you can.

Winner of Classic Boat Design Competition 2010. 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. Watch video here.

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