No harm in one of you locals phoning the CG to tell them, with some details including boat name if someone has got that. It may well be that the owner is blissfully unaware.Hope so! You can probably see it from the West Mersea Lifeboat Station...
If the owner knows about it, but is abroad, why doesn't he get the yard or someone to attend to itThe owner often works abroad so probably unable to take action before the storm. As I understand it he does know the situation.
