I am not upset with any of the folks who were on the boat. Should they have come for us? Yes. OTOH, I can see why they did what they did. I didn't hang on the surface for confirmation. I couldn't, but they didn't know that. Everything about this dive was unusual. I've never seen sharks act like this except around spearfishing and this was more extreme than anything I've experienced even then. Denial is common in us all. When one person gives a quick distress signal and immediately disappears, a very experienced diver might think, that looks extremely unusual, I'd better get there ASAP. OTOH, I'm sure most divers with Tracy's experience level would have acted in a similar manner. Asking for confirmation of the distress signal, makes sense, getting an OK in response means sit tight. I can't fault them at all. OTOH, I know everyone on the boat, including Lil Sis with her 5 dives of experience, would react differently today to any distress signal. Every dive is a learning experience and everyone (3 in the water and 3 on the boat) learned from this one.
