I've been sailing off this beach for 30 years with no incidence, ever. I have shore crew per se, to clear an area for me to land. I take offence to your statement that I'm not in control of my boat. To move to another area would be nearly impossible, and my house is 4 streets off the ocean. There is no catamaran friendly area within 25 miles of my location. I am totally aware of the risk involved and take all precautions to avoid swimmers. I also surf and am forced to go to a specific area to surf, the swimmers are not restricted from that area. So, exactly where would you propose I find this protected "catamaran friendly" area?
