Introduction to the OK-Dinghy


Technical Overview

By Donald Andrews

Technically speaking, the OK Dinghy is :

  • a single handed dinghy
  • 4 m long
  • 1.5 m wide
  • 72 kg hull weight
  • hard chine construction
  • built of wood, grp or 'composite'
  • home built or professionally built
  • sailed by men or women between 60 - 95 kg (or less or more!)
  • a mast of carbon fibre - though this may be of wood or aluminium
  • foils of wood, which may be sheathed with grp (metal centreboard is permitted)
  • a sail of 8.5 square m
  • comfortable side decks and 'sitting out' position
  • rig, sail and controls chosen to suit the owner's physique and personal preferences
  • controls which effectively control sail shape
  • full and reliable buoyancy arrangements

The OK is inexpensive to campaign : new home built boats, competitive at any level, have been put on the water for less than 2,500 Euro.

Even this price could be reduced if previously owned equipment, such as a cut down Finn mast, were used.

The very top of the range, ready to sail, new boat would cost about 8,000 Euro.
Competitive, previously owned boats can be acquired for as little as 1,500 Euro.

Trim guide

Nick Craig wrote a brief trimming guide, older guides are not much help anymore as the class went for carbon masts in 2003.
The guide is in pdf format, for easy print out.
