Over water scheds are a must and cost nothing, at 3000' you are never out of sight of land via Cliffy, Hogan, Deal, Flinders. Life jackets must be worn in a single and carried in a twin, life raft not req'd
Now I think I better brush up on the CAR's and O's, but my memory is they need to be worn when operating below 2000ft when over water, and not approaching or departing an aerodrome.
