First of all, that a video camera was in use is a symptom of the world today. wow. I too have experienced being under a turtled boat and tangled in lines and rigging. It is the event that made me realize that a sheath knife accessible with either hand is essential, not a folding knife.
Have a safe and happy thanksgiving. I guess thanksgiving is a holiday where we reflect on family and friends. I hope you are all able to have a moment of reflection.
