Self Build Boats

"A philosophic attitude behind the Wharram designs is that 'urban man' can, with a little financial saving and some handcraft work, create an object of beauty. This object of beauty can then, for a period of hours, days, weeks or months, carry him/her out of the urban world into a natural never-never land; the seas and oceans; to a time when the world was young; when Mankind was directly and intimately interacting with the beauty and power of nature. There are hundreds/thousands of Wharram builders or, as I prefer to call them, "Sea People", who have done or are now doing that!"

- James Wharram

Tiki / Coastal Trek Designs

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.

Hitia 17

Hitia 17

Hitia 17 is the perfect beach catamaran, but also capable for use as a micro Coastal Trekker. Her wingsail sprit rig with low centre of effort gives good drive and great stability. The sail can be reefed and hence the boat can always be sailed safely without the risk of capsize, which most other beach cats are prone to. She has skegs and rudders that do not project below the V-eed hull, hence she can be sailed straight off the beach without lifting rudders or daggerboards.

She has stowage space within the hulls and the two self draining 'cockpits' are big enough to sit in, or stow camping gear for a longer Trek. The boat can carry four adults. The deck is designed to take a standard two-man dome or pop-up tent, or you can make your own decktent to drawing supplied. Can be carried on the car roof of a bigger car or is easily trailed. A lovely minimalist coastal explorer.

Tiki 21

Tiki 21

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 nearly 1000 Tiki 21 Plans have been sold (2015).

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.

Winner of the Cruising World Design Competition.

Mana 24

Mana 24

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.

Whilst exploring this idea we look sideways into the world of camping and the living equipment you need for a camping holiday bought at a reasonable price, as against highly priced yachting equipment.

All these ideas have come together, resulting in the new MANA 24 design, a catamaran specifically designed for trailer sailing and designed to be built from a CNC cut plywood kit.

Building Method: Ply/Glass/Epoxy/Laminate
Length Overall: 23' 6" 7.16 m
Beam Overall: 12' 8" 3.85 m
Waterline length: 20' 10" 6.35 m
Beam of each hull: 3' 2" 0.97 m
Max draft: 18.5" 0.47m
Headroom over seat/bunk: 3' 0.90 m
Sleeping capacity: 2 single bunks in hulls, double birth under decktent
Dry weight (approx): 1190 lbs 540 kg
Maximum displacement (Approx): 2510 lbs 1140 kg
Sail area: 216 sqft 19.6 sqm

In trailer/sailer design every increase in length equals harder launching and recovery work. At 23’6”- 7.15m hull length MANA 24 sits between our TIKI 21 and TIKI 26 designs (both very popular trailer sailers), with easier launching and handling like the smaller TIKI 21, but an interior space close to that of the Tiki 26. Her new chined hullshape gives more width for the bunks, which are placed aft where the hulls are widest.

Mana will not be available as Plans, only as a CNC cut plywood kit. Building from such a kit takes away the worry of measuring and cutting all the boat parts, which can be quite daunting to many first time builders and saves a lot of time in the early stages of building. The ply parts will have a first smooth coat of epoxy already applied, cutting down time in coating and sanding, so within a short time you will be able to assemble the hulls and see the boat you are building. As she is built from a pre-cut kit, we have been able to give the Mana more complex and beautiful shaping, giving her more interior volume than the Tiki designs. During construction all the kit parts slot together and are locked with wooden wedges, so no room for error. Even all the stitch holes (for fastening joints with cable ties) are drilled and lines scribed where to glue on bearers and stringers.

The Mana prototype was launched at our HQ in Cornwall on 20th August 2016 and is being sail tested during 2017.

Pahi Designs

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.

Pahi 31 - Areoi

Pahi 31 Areoi

The first of the Pahis, designed in 1979 after the building of a 35ft prototype, which successfully sailed the 1978 Round Britain Race.

The PAHI shape has proven itself in rough weather conditions, in speed potential and ease of motion. At only 31' she is still capable of ocean voyages. Standing headroom is under a large raised hatch.

The original Pahi 31 rig is a Bermudan cutter, with low cut, anti-twist, loose footed mainsail, but now she is also available with the Wharram Wingsail Rig, giving more clear centre deck space as the mast is placed further forward.

Pahi 42 - Captain Cook

Pahi 42 Captain Cook

The Pahi 42 is a good size for family long distance cruising.

The deck pod was a new venture for James Wharram Designs in 1980. Not only does it provide shelter for the steering / watch crew, but a sleeping cabin for the skipper or navigator to be on instant call and has been appreciated by the many builders.

Pahi 63 - Gaia

Pahi 63 Gaia

The Pahi 63 is a tribal boat, suitable for expedition sailing and for larger groups of people to cruise or eco-charter.

The deck/accommodation layout resembles a village, with a central public area including ‘well’ and (optional) ‘hearth’, surrounded by private cabins. This centre deck and the separate aft and fore deck areas give three large emotionally different spaces, enabling people to have hours in seeming solitude.

This deck layout combined with the 'Flexi Space' hull cabins (all with their own entrance) enables 8-10 people to live peacefully together for weeks at a time.

The Pahi 63, based on traditional Polynesian double canoe principles, is most suitable for use in warmer climates.

Ethnic Designs

The Ethnic designs have been a new development at James Wharram Designs since James and Hanneke sailed extensively in the Pacific. With everything self-made these boats are lower cost to build.

Ethnic Designs cater for those who want a "traditional" Pacific sailing craft, built using appropriate modern materials and methods, but without trying to Westernise them. These designs arose after requests from Pacific Island peoples for James to design craft to overcome shortages of "traditional" building materials, but which closely reflect the cultural and ethnic origins of these craft.

Melanesia

Melanesia

The Melanesians have been building outrigger canoes for thousands of years. The 16ft Wharram MELANESIA design is a very simple and economical to build outrigger canoe, based on the original Pacific canoes.

Designed in 1997 for a small island in Vanuatu where trees for the native dugout canoes were getting scarce.

The main canoe hull is built from just two sheets of plywood, stitched and glued together with epoxy and glass tape. All other parts are constructed from naturally grown saplings/timber. She is steered with a steering paddle and uses a traditional hand made 'crabclaw' sail.

The paddling version uses a more curved laminated float and two shorter laminated crossbeams.

The plans contain drawings for both sailing and paddling versions.

Building Method: Ply/Glass/Epoxy Stitch & Glue
Length Overall: 16' 4.90 m
Length of Float: 12' 3.65 m
Weight of Hull: 46 lbs 21 kg
Overall Weight (sailing version): 110 lbs 50 kg
Overall Weight (paddling version): 75 lbs 34 kg
Sail area: 58 sqft 5.35 sqm
Building Time Estimate: 115 hrs

Tahiti Wayfarer

Tahiti Wayfarer

The Tahiti Wayfarer hull shape is derived from traditional dug-out canoes from Tahiti and Samoa, but built in stitch & glue ply/epoxy. All other components of the boat are constructed from materials found in nature. Crossbeams and spars are made from small trees and saplings with natural forks for jaws, stripped of bark and sculpturally finished, all parts are lashed together.

As she is likely to be used in the open sea she has a self-draining floor (large enough to sleep on) and watertight bow and stern compartments. This hull shape has only 8" - 20cm draft; her lateral resistance comes from a fine forefoot combined with the area of the steering-paddle/side-rudder.

Building Method: Ply/Glass/Epoxy Stitch & Glue
Length Overall: 21' 6.40 m
Beam overall: 10' 3.00 m
Waterline length: 17' 9" 5.40 m
Draft: 8" 0.20 m
Weight (Double Canoe): 485 lbs 220 kg
Weight (Outrigger Canoe): 330 lbs 150 kg
Loading capacity (Double Canoe): 790 lbs 360 kg
Loading capacity (Outrigger Canoe): 395 lbs 180 kg
Sail area (Small): 84 sqft 7.6 sqm
Sail area (Big): 143 sqft 13 sqm
Building Time Estimate: 300 hours

She can be built as a Double Canoe with two same-sized hulls and a platform big enough to erect a two man tent on, or as an Outrigger Canoe using just one hull and a light weight log as outrigger float. She is rigged with a crab claw sail, using rope standing rigging. Tahiti Wayfarer with her very shallow draft is a perfect boat for exploring, a great boat for use by scouts and youth groups or to be taken on a ‘Raid’. Auxiliary propulsion is by paddle, oars or Yuloh.

By self-making everything: natural spars, sails and even hand carved deadeye blocks, her building cost is very low (the Plans give all details). This is a boat that needs NO hardware! The aim of the Wharram new Ethnic Design range is to study and understand by practical experience aspects of the design of canoe form craft from the ancient sailing world.

Amatasi

Amatasi

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. 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.

Building Method: Ply/Glass/Epoxy/Laminate
Length Overall: 27' 7" 8.4 m
Beam overall: 13' 10" 4.2 m
Waterline length: 23' 4" 7.1 m
Draft (Max): 1' 2" 0.36 m
Weight (Approx): 990 lbs 450 kg
Loading capacity: 1540 lbs 700 kg
Sail area: 242 sqft 22 sqm
Building Time Estimate: 650 hours

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!

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.

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

Tama Moana

Tama Moana - Child of the Sea

The Tama Moana (Child of the Sea) has the traditional hullshape of the islands of Tikopia and Anuta. She is built in strip planking over plywood backbone and bulkheads. Her rig is traditional crabclaw and she is steered with steering paddles/side rudders.

Ethnic Designs as Canoe Craft have a basic design principle of maximum boat for minimum cost. Building and sailing one you can be a research participant in a major attempt to recover and preserve the practical, design, handling aspects of Man's first offshore sailing vessels.

Two Tama Moana designs sailed the Lapita Voyage from the Philippines to Tikopia and Anuta in 2008-9, where they were donated to the island populations who are now using them as their autonomous transport.

Due to its simplicity this design is also a very economical boat to have ready-built.

Building Method: Strip Plank/Epoxy/Glass
Length Overall: 37' 9" 11.5 m
Beam overall: 14' 11" 4.55 m
Waterline length: 28' 5" 8.65 m

Classic Designs

The early 'Wharrams', now known as the Classic Designs, are recognised as beautiful, safe boats - easy to build, and easy to sail. Many anchorages around the world are graced by these Classic Designs, and of the seventeen drawn between 1957 and 1976, nine are still available, from the 16ft Maui to the 51ft Tehini.

They were the first range of Wharram catamarans, designed in the 1960s and 70s, based on the sea experience of James Wharram's pioneering ocean crossings. They are sturdy, very stable, but relatively basic in design. They are built using simple plywood construction over a backbone and bulkhead frame.

Tanenui

Tanenui

Based on the 1960s 27' TANE design with more beam and higher freeboard, she can be built in foam/GRP sandwich or in plywood.

The Classic hull seaworthiness of the TANE encouraged many people to make ocean passages on her. We designed the TANENUI in 1973 to give these people on a low budget a sturdy, seaworthy basic boat with just that bit more internal space than the Spartan TANE.

Narai Mk I & Mk II

Narai Mk I and Mk II

The NARAI design is a direct descendant of the 40ft RONGO on which James made his pioneering voyage across the North Atlantic in 1959.

NARAIs have been rigged as junks, Polynesian sprits, Bermudan ketch, Bermudan cutter or gaff schooners - powered by deck mounted diesels or outboard engines, the NARAIs attract the pioneering type. Now also available with the Wharram Wingsail rig (extra package).

The Mk I is the basic design. The Mk II has an extended centre cabin, giving more accommodation space. Drawings for both included.

Narai Mk IV

Narai Mk IV

After considerable experience with the Narai Mk I and II we brought out a new design to get more volume on the same length. The Narai Mk IV has wider individual hulls and increased headroom by raising the decks to the level of the gunnels and placing the cross beams in beam troughs. This is a very sturdy ocean cruiser with many ocean crossings and circumnavigations to its name.

Read 'Katipo Voyage' by Don Brazier - A story of a Narai Mk IV sailing 5,500 miles from New Zealand to some of the South Pacific islands and back.

Tehini

Tehini

The TEHINI is breathtakingly beautiful. She has a timeless look about her and dominates any harbour with her rakish, piratical looking lines. James built this boat as his own and spent 10 years living on her with five others.

The Plans include a design update, increasing accommodation space and overall beam.
