I also had the opportunity to dive with Dave on the Seagull and it was always fun. I remember seeing Dave get mad at something one day, tear out his VHF radio and throw it overboard. On another occasion, our dive became a salvage dive when the mate through the hook over and then realized that the anchor line was not attached to the boat. Dave was a character and also one of the sweetest guys that I knew. Here is a photo of him with a scooter taken on the Spartan many moons ago. God rest your soul, Dave! We will miss you.
