Years ago, had a 65' Trumpy I ran for dinner charters out of Little River, SC. Standing rule
for all customers-"Do not do anything unless I tell you what to do!" We tied alongside parallel to a pretty strong current
. Use to run a spring line around a piling when leaving to allow the bow to swing into the current
. Had a passenger who saw the bow start to swing out and the line around the piling and thought we were still tied to the dock
. He did not say anything, just put on foot on the dock
, one on the boat, grabbed the line and fell in as we were pulled into the current. The only thing for him to grab was a barnacle encrusted piling! Not a pretty sight.
