We will now review at a few cases looking at how the new Rule 19 works. 

Yellow, Blue and Green were sailing on a run with Yellow and Blue approximately a boat length apart. At position 1 Green is clear astern of both Yellow and Blue. At position 2 Green, sailing faster, obtains an overlap with both Yellow and Blue. When the overlap starts there is not adequate space for Green to pass between Yellow and Blue. After the boats travel approximately 2 hull lengths Yellow must alter course to keep clear of Green. At no time does either Green of Blue alter course. 

Questions: 
1. At position 1, who has right of way Yellow or Green? 
2. At position 2, who has right of way Green or Blue? 
3. At position 3, what Rule(s) were broken by Green? 
4. At position 3, what rule(s) were broken by Yellow?
