Kaya,
Anchoring on the south side of wisteria (christmas tree) island will give you some shelter from the north but it's rolly from wakes (especially in the early morn. when the
charter boats go out). Holding is fair but use caution. It's a short dink ride across the channel to the harbor where the dink
dock is (payment enforcement haphazard... meaning you never know so just pay). note: going back across the channel in a northerly blow can be extremely rough and wet.
Also remember that K.W. has been pirate country for centuries... and still is. Use common sense and you will have a great time.
PM me if you like and I can give you some more info about K.W.
cheers,
mm
