Facts Found

In continuation of yesterdays post a new TSS-diagram.
A little different than usual, because the appropriate rules are included in each position, and I'll give you the decision: Yellow is DSQ for breaking rule 11
Here is the animated and static picture:









The purpose of this exercise is to write the facts found and draw a conclusion which matches this decision.

When you are in a real protest-hearing this is something which you should never do! It is called "cooking the books". When you have a conclusion and/or decision, you can always find a way to write the appropriate facts. And it should be the other way round. However, for the purpose of this exercise - it is allowed.
Try to write a list of facts covering each position, without drawing any conclusions in that list.
Use the comments button to publish your view on facts found and then draw a conclusion.

  1. Facts found

    Yellow and Blue were on Port tack

    Yellow sailing faster, obtained an windward overlap within 2 hull lengths of blue

    Blue slowly change course to windward

    Yellow kept cleaer by changing course to windward

    Overlap was broken, yellow was clear ahead

    Blue obtained overlap within 2 HL to leeward of Yellow as result of Yellow changing course

    Blue changed course to sail in the direction of the next mark

    After sailing 4 boat lengths contact occured with no damage

    Conclusion
    Yellow as windward boat failed to keep clear of Blue.

    Yellow is DSQ
    RRS 11

  2. I've made a few suggestions how to improve:

    Facts found
    Yellow and Blue were on Port tack
    I would also add: ……, sailing on a beam reach on downwind leg, with Blue 2 meters in front and half a boat-length to leeward of Yellow

    Yellow sailing faster, obtained an windward overlap within 2 hull lengths of blue
    Better: Yellow sailing faster, obtained a windward overlap, with a distance between the hulls of half a boat length; (within 2 BL is already a conclusion)

    Blue slowly change course to windward
    Fine

    Yellow kept clear by changing course to windward
    Better: Yellow luffed also, there was no decrease in distance between the boats. (kept clear is a conclusion)

    Overlap was broken, yellow was clear ahead
    Or: Yellow sailing faster on the inside track, luffed to close hauled, and became clear ahead.

    Blue obtained overlap within 2 HL to leeward of Yellow as result of Yellow changing course.
    Better: Yellow bore off and Blue became overlapped to leeward at a distance of half a boat length

    Blue changed course to sail in the direction of the next mark
    Fine but add: Yellow also bore off on a slightly lower course.

    After sailing 4 boat lengths contact occurred with no damage
    Fine and add: Neither boat did any penalty turns and finished the race

    Conclusion and rules that apply:
    Yellow as windward boat failed to keep clear of Blue.
    Better: Yellow to windward did not keep clear of Blue to leeward, RRS 11.

    Decision:
    Protest is upheld, and Yellow is DSQ

    Key in this process is to avoid drawing conclusions in you facts found.
