According to the MCA extended rules and occasional plays, this occurrence "… can only be completed when each of the UK shipping areas has been used."
The player failing to play an available UK ocean area must pay the penalty by surrendering his/her home station and all prime colour line usage for a further 15 moves.
Failure to follow this imposed penalty will mean the offending player must not use a station with the letter 'i' in it for the remainder of those 15 moves, plus a further 15.
Failure to comply with this further penalty will automatically allow the opposing player/team to play the winning move, but only if that move is made directly after the penalty breaking move is made.
This is top rank play that has only been seen at Olympic Exhibition match play and the occasional stray friendly.
