RRS 14 and the Lee Bow manouevre
Created: 18-Apr-13 13:03
A recent protest which involved a consideration of RRS 14 led me to an issue not included in that protest.
The question is how does RRS14 affect a starboard tacker when a port tacker who if they continued would hit at the stays of the starboard tacker decides to lee bow the starboard tacker? in a practical sense when does the starboard tacker lose the protection of 14 a "However, a right-of-way boat or one entitled to room or mark-room (a) need not act to avoid contact until it is clear that the other boat is not keeping clear..."
Assume you are the protest committee with great video of the situation and witnesses that prove the scenario.
When is the first time S can tack away and successfully protest P for not keeping clear? (please answer in boat lengths)
When is the last time that S can hold course and, if a collision results, still have taken action when it first becomes clear that the other boat is not keeping clear? (please answer in boat lengths)
So how long is the distance in which S can tack away and protest successfully and avoid a collision?
Is the difference between P just keeping clear and causing contact which S failed to avoid so fine that it is a catch 22 situation where S cannot win a protest if they (S) tacks away tack away?
If P decides to establish a lee bow situation against S (given that the otherwise contact point is at, but not behind, the stays) will there be a time before P starts to turn and when S can tack away and successfully protest?
Are the answers different depending on the wind speed, boat speed and sea state?
Are the answers different if the boats are not on roughly perpendicular courses? Eg S boat heading 270 (W) with P boat heading 45 (NE)?
