Same thing happened to me with that ball about 4 years ago...some boat came and said it was reserved and I said prove it and they couldnt. I believe it was a Coco Loco ball and they came out as well. He finally relented.

Leaving the next day it was windy and the field has lots of boats. Long story short although I have plenty of time on the 514 PC the pendant drifted and I clipped the line and it wrapped the prop so limped out on on one engine dodging boats to open water where we dove and untangled the prop with no damage to the boat

The boat passed us on the way with dirty looks in to get their ball (sans pendant)....

The pendant hangs in my basement as reminder to stay humble and hungry....not a proud captain moment but karma is a bitch
