Our group was sitting on the beach in front of SD. The loose sheet had been flapping in the wind for at least 15 - 20 minutes prior to being knocked into gear , which had many people looking around the West side beach for the Captain, as it was causing quite a bit of noise. My understanding is that Captain was down at Ivan's.

Hats off to the several other boaters who reacted pretty quickly, boarded the stray boat, brought it under control and re- anchored well away from the busy part of the anchorage!
