To be serious, I wear my lifejacket / harness every time I go to and from my boat in the dinghy to and from the mooring.
However the most useful bit by far is having a harness point.
I wear a buoyancy aid in the dinghy, because if I fall in then I want to be able to swim. On the boat I clip on whenever the boat's under way and I'm on deck. By a convenient coincidence, by harness has a lifejacket attached.
