The Wētā 4.4 Trimaran is a 4.4 metre (14 foot) sailing dinghy conceived and developed in New Zealand from 2001-2006 by Roger and Chris Kitchen and others with original drawings by TC Design's Tim Clissold.
Design
[edit]The boat is constructed from fibreglass and carbon fibre, and is popular as a racing boat or for recreational sailing.[2] It has added stability and righting moment from the trimaran amas or floats.
Recognition
[edit]The Wētā Trimaran is recognized as one design class by Yachting New Zealand,[3] the French Sailing Federation,[4] and the Royal Yachting Association in the UK.[5] It has been approved for the Paralympics[6] and World Masters Games.[7]
Awards
[edit]In 2010 the Wētā Trimaran was awarded Boat of the Year by Sailing World magazine.[8]
Builds
[edit]There are two distinct builds of the Wētā Trimaran, the 'original build' and the '2015 Wētā' which was created from a new mold and included (mostly internal) hull revisions. In April 2017, Wētā announced the availability of a foam-core Wētā which as well as being stiffer is right on the minimum weight of 120Kg in the class rules.
Original build
[edit]Early prototypes were produced in New Zealand but from 2006 to 2014 the 'original build' was manufactured in China for Wētā Marine and sold internationally.[9] In 2020, 1300+ boats have been sold to date with the largest fleets in France and the USA.[10][11] The original sails were manufactured by Dutch windsurfing sail-maker, Gaastra.
The design evolved over time:
- Color changes (Most boats were produced to four RAL color codes: Red (3020), Yellow (1018), Green (6018), Light Grey (7035). Some very early boats featured alternative red and yellow hues). Current 2020 colours are White, Grey, Blue, Yellow or Orange.[12]
- Three rudders
- New deeper daggerboard
- Mylar sails (dacron optional)
- Minor modifications to forestay tack fitting
- Optional furling jib
- Optional mainsails:
- Small training mainsail
- Heavy weather mainsail
- 'Resort' mainsail (Dacron)
2015 Wētā
[edit]In 2014 the new 2015 Wētā was announced with a switch to a new manufacturer,[14] Xtreme Sailing Products (XSP), based in Singapore (with the factory in nearby Batam, Indonesia). XSP produced a new mould and made structural and cosmetic improvements, including:
- Deck (screecher furler cleat on cockpit side, swaged stays, Liros ropes and optional hiking strap, enhanced grip, new raised foredeck detail for enhanced strength and durability)
- Floats (Change to seamless construction and removal of rear lip. Switch to Nairn hatches.)
- Sails (Switch of manufacturer to North Sails)
- Centrecase (precision fit via nylon pile)
- Trampoline (improved alignment via custom carbon pads)
- Rudder bar and gudgeons (strength and durability enhancement)
In September 2014 the first of the new '2015 Wētā' build were shipped to customers in the US.
2017 Foam Core Wētā & Square Top Sail
[edit]In April 2017, Wētā announced the availability of a foam-core hull (right on the class weight limit of 120Kg) and bi-radial cut 9.3 m square top mainsail (compared to the original Pin-head 8.3 m mainsail. Nearly all Wētā built since 2018 have been foam core and the Square Top sail has been adopted as the standard sail for racing in most regions.
2020 Self-tacking jib kit
[edit]In February 2020,[15] Wētā announced the availability of a Self-Tacking Jib kit designed to be retrofitted to existing hulls or as an addition to new boats. The kit allows tacking without adjusting the jib sheets and includes a slightly smaller jib which is 3.0sqm. Around 6% less sail area than the standard jib at 3.2sqm.
2020 Twin Tiller Extension kit
[edit]In August 2020, a twin tiller extension kit was announced. The kit consists of a second tiller extension, bolts to attach both extensions to the tiller and a shock-cord and ring system to prevent the inactive tiller dragging in the water. The benefit is that you no longer have to pass the tiller around the stern when tacking.[16]
2022 Branding Revision
[edit]In April 2022, the branding was changed from "Weta: Fun. Fast. Easy" to "Wētā: Life's Better". The addition of the macrons was made to properly align with the Māori language definition.
