We had an out of water survey done on the boat in August. The following is one item that was flagged for correction: “The following conditions were found that are violation of US law or regulations. The seven fire extinguishers aboard are due for inspection/recharge by a licenced technician. Tags/log should be noted when completed. All should be mounted and readily available.” Questions: Is the requirement for licenced technician a real requirement? If so how often do you need to get it done? If you purchase new extinguishers how long are they good for? Is self-inspection acceptable? Comments: We had one extinguisher loose in the forward cabin all others were mounted. The reason for 7 I have one in each area of the boat. Each year I look at them and if the needle is in the green I assume they are fine.
