1. You can be disabled and anchored or disabled and adrift (see below). Disabled means unable
to proceed under your own power and/or control.
Adrift = not under power/control and not attached to a fixed point.
You can be adrift and still be stationary if there is no wind
or they are in opposition.
Drifting = moving solely under the influence of wind
You can be drifting without being disabled. (It's dead calm. I could fire up the motor
if I needed to, but I don't want the noise
, I don't want to use diesel
unnecessarily and I have plenty of time, so I will just drift)
