Re: pulled anchor and sailed away...
On my little boat I get the sails up and luffing, pull in the anchor rode and chain so that the boat is right over the anchor, and when I sheet in the sails and lock the tiller the anchor releases without fail. I pull the anchor up all the way (almost all the way if it is covered in mud), and I get going.
I don't like using my outboard engine unless I absolutely have to.The noise and smell (it's a 2 stroke Nissan) always harsh my morning mellow so I would rather paddle a short distance than use it early in the morning. Small boats often make life easier and quieter.
Be kind, for everyone you meet is fighting a hard battle.
