Good questions, thanks for asking and caring about preserving access. It sounds like you are already walking way upwind of the out of bounds area while you are still working on riding/staying upwind, excellent. People need to know that if it is blowing out of the S to SE they need to go way to the south and walk back well before the hobie cats on the beach. Or, if it is blowing from the N to NE to stay well north of Atlantic Dunes Park a mile to the south.
People do need to stay out of the sea oat dunes to the west of the beach in the area encroaching on all the homes. I see guys flying full sized kites with no flying skills dropping kites into the dunes or sending them flying off into these private properties. This is only going to annoy these residents who took a good shot at banning kiting here a while back. By stupidly cheaping out on adequate quality pro lessons they are putting all our access in harms way not to mention themselves potentially plowing headfirst at speed into a dune scarp, line hazards, etc..
Going to the south, you need to stay at least 100 yards to the north or offshore of Atlantic Dunes Park just north of Linton Blvd. They have just one lifeguard stand that shows up pretty well from the water. More about the park at:

"3. Are dogs permitted on the beach or in any city park?
Dogs and other pets are prohibited in all city parks, including the Municipal Beach and Atlantic Dunes Park. The exception to this is the use of the sidewalk of A1A. Please use a "doggie bag", located at various locations along the side walk to help keep the area clean. Palm Beach County Parks and Recreation has designated a Dog Park located in Lake Ida Park"
It comes down to enforcement which is fairly active on the guarded beaches during the day. The area between the guarded beaches may have little enforcement. If dogs start attacking kites or getting caught in lines on launch/landing that is a whole different problem. It has happened before.
This is from the recent 60 mile race. I put it in here to draw attention to the "no kites north of this line" location.
