It is 14 feet long, sporting a large sail area, single trapeze and asymmetrical spinnaker.

The Javelin is a development class, meaning that boats vary in shape within a framework of rules, rather than being all built to the same design.

Its lightweight 70 kg (150 lb) hull, and powerful, efficient sail plan allow it to exceed speeds of 25 knots and provide an exhilarating "ride" with exciting fleet racing.

The two countries race each other every second year in the Javelin Class South Pacific Championships, sailing for the "Air New Zealand Trophy".

The Javelin class sail each year for the Sanders Cup, with only one entry from each region in New Zealand allowed.
