The Wētā 4.4 Trimaran is a 4.4-metre (14-foot) sailing dinghy conceived and developed in New Zealand from 2001 to 2006 by Roger and Chris Kitchen and others with original drawings by TC Design's Tim Clissold.

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.

The design evolved over time: [13] 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: In September 2014 the first of the new '2015 Wētā' build were shipped to customers in the US.

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

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.
