Class Rules & Guidance



The International Topper is a strict One-Design single-handed dinghy designed in 1977 by Ian Proctor to promote racing in a simple, low cost boat suitable for all ages and skill levels.

The fundamental objective of these Class Rules is to protect the One-Design nature by ensuring that International Toppers are as alike as possible so that racing success shall depend only on the skill of the crew and not be a test of the boat or its equipment.

The Class Rules are also intended to ensure that the boat's characteristics of simplicity of rig, safety, suitability for sailing by inexperienced as well as experienced helmsmen, constructional strength, ease of maintenance and moderate cost shall be maintained.
