Other information:

Boats that have not won a 1st ,2nd or 3rd prize in any of the three Friday series or pursuit series of the current year are eligible.

In future years,  3rd prize winners could be eligible at the committee’s discretion.

Scoring:

The scores of all eligible boats that have raced in PY and GH classes in the Friday and Pursuit series is re-calculated using a DNC (did not come to the starting area) score equal to the total number of eligible boats + one.  All discards stand as in the original series scoring.

The boat with the lowest score wins.

Ties will be broken by the greatest number of race starts, then (if necessary) by comparing best race scores, then by comparing scores in the last/penultimate race.

The shackle holds a significant place as a yacht racing prize, probably the first occasion being last century in Antigua, where the ‘Rusty Shackle Trophy’ is still competed for.
