I dont mean to be pedantic FlyingKiwi but you are all but correct. Life jacket worn (and life rafts carried) if exceeding 10Nm beyond gliding distance from shore if its a commercial operation. Private ops you dont have to wear a life jacket at all but it must be carried (one for each POB) if you are beyond 50Nm from shore. Private ops/single engine beyond 100Nm require liferafts (or beyond 200Nm if multi engine)
