Part 4 — When Boats Meet

Section A — Right Of Way

A boat has right of way over another boat when the other boat is required to keep clear of her. However, some rules in Sections B, C and D limit the actions of a right-of-way boat.

42.1

Basic Rule

Except when permitted in rule 42.3 or 45, a boat shall compete by using only the wind and water to increase, maintain or decrease her speed. Her crew may adjust the trim of sails and hull, and perform other acts of seamanship, but shall not otherwise move their bodies to propel the boat.

Definitions in Context

Rule
  • (a) The rules in this book, including the Definitions, Race Signals, Introduction, preambles and the rules of relevant appendices, but not the Basic Principles or titles;
  • (b) World Sailing Regulations that have been designated by World Sailing as having the status of a rule and are published on the World Sailing website;
  • (c) the prescriptions of the national authority, unless they are changed by the notice of race or sailing instructions in compliance with the national authority’s prescription, if any, to rule 88.2;
  • (d) the class rules (for a boat racing under a handicap or rating system, the rules of that system are ‘class rules’);
  • (e) the notice of race;
  • (f) the sailing instructions; and
  • (g) any other documents that govern the event.

Case 8
