BLUE WATER

Longish ocean passages are tempting (to me anyway) as
getting away from turbulent landwinds is a fantastic buzz.  
Some suggestions:
1.    Use a quick release harness, arm strain becomes unbearable after
      even 15 minutes holding one tack.
2.    Keep an extensive shoreline downwind of your position in case you
      have to get back by paddling or drifting.
3.    Use an escort boat.
