I would analyse what was happening to make an assessment of what was happening . This would enable me to be focused on the task and reduce my stress. In the past I have had to deal with major accidents on the water. The worst being when a chentleman fell over board with a rope around his leg. This was dragging him face down. If I had panic he would of drowned instead I stopped the boat and got his head above water. Then checking his legs dealt with the major bleeding that had happened.
