The Tangaroa Mk IV was a design that evolved from the Tangaroa Mk I, James’ first design for which he drew Self-building Plans in 1965.

The Mk IV has more graceful hull lines, wider hull beam, more freeboard over the bunks and a longer cabin with standing headroom, so it is not to be mistaken for the Tangaroa Mk I of which many are still sailing.

Self-build boats - Tiki Range

From the car trailable TIKI 21 - Winner of the 1982 Cruising World Design Competition, to the TIKI 46, a spacious ocean cruiser or charter boat.

The TIKI range offers car trailable Coastal Trekkers to long term live aboards. On the larger TIKIs the 'Deckpod' offers sheltered steering and the 'Stern Ramp' provides easy access to and from the water. The TIKIs are boats you can work and live on.

All TIKI building Plans are very detailed, supplying a building sequence as a book of 3-D sketches, which some builders have described as a course in boat building.

The Wharram approach goes beyond simple boat design - the concept of 'Flexispace' puts emphasis on not just the physical living area, but also the 'mind space' of those on board.

Self-build boats - Pahi range

From the Coastal Trekking Pahi 26 to the impressive 63' flagship of the Wharram fleet 'Spirit of Gaia' - the PAHI shape is more evocatively 'Female' than the Classic Wharram designs.

Constructively, they are simpler to build, using epoxy fillets instead of more difficult wood joints. They are designed to use quick growing softwood plys, coated and glassed with epoxy to achieve a durable finish.

The PAHI designs were the first to use rope lashings to attach the crossbeams, giving a shock absorbing effect, without the need for metal fittings.

The Pahi 42 'Captain Cook' design set fresh ocean cruising standards when she was designed in 1979.

The Pahi 63 was designed in 1986 and launched in 1992 to become the new ocean going flagship for the Wharram family. During the construction of 'Spirit of Gaia' many unique new solutions to plywood and epoxy building methods were developed, which were later incorporated in the larger TIKI and ISLANDER designs.
