Interesting post. I was on a Ventura sportboat last year and we whacked the seabass. The report that night showed only a couple caught on the boat that day. I called the landing and asked why and they said it keeps the smaller private boats away from chasing them all day.
Interesting post and comments. May I suggest you call or visit him. Explain your side on what you think happened. If that holds no resolution than simply file a coast guard report for unsafe boat operation.
