Yes I sailed right by, and that was many years ago and to my shame you weren't the only one I did that too. At that time I was a bit ignorant about the risks of our game.
Reading about the many close calls and some tragic events on open water and bouy races I don't sail right by anyone anymore.

If I'm in the proximity of a down boat, I'll stop and at a minimum get a verbal acknowledgement that they are okay (even if it's you Todd) regardless if it's an open water event or bouy race on a closed body of water.

Granted I've had a bit of a wake up call of my own that has given me a sharper focus on this so I'm probably in a different place than you are regarding this issue.

For me things are a little different now.
