I have owned a 12 year Beneteau for the past 8 years, it has an electric bilge pump which can be operated by either forcing on or selecting a float sensor in the bilge. The boat is kept in a marina on shore power, when I leave I always switch the main isolators to off, both to protect the batteries & a fear that live panels could be a fire hazard. What has recently occurred to me is that because this de activates the bilge pump I may be taking a greater risk of sinking if there was a seacock failure, would I be better to leave the power on? Which is the greater risk fire or sinking? What do other people do?
