Unthinking enforcement of rules can have some unfortunate side effects. When some bunch of desk bound bureaucrats start enforcing life jacket wearing (and/or carrying) on every short dinghy trip they are increasing the exposure of the jackets to sand, salt water, UV, theft, and more importantly, when things do go wrong instead of the jackets being in the emergency grab bag, or some other specific location, the life jackets will be who knows where - in the dinghy, on someone's bunk, in a bag somewhere.... After 40 years in aviation I'm pretty sure that safety is not something that is achieved
