I don't know about the details of the site but the enviro-wackos will have a sh*t fit with anything that resembles an ATV on a dune. I sorta have the same problem around here with access. I believe access is closed because you get the 'once a year' sailor with a bad boat out there blowin' 20knts and then something happens. The officials think they have to prohibit catamarans for your personal protection or something. And then you have the boats that are left on the dune for months or a year at a time (actually contributing and becoming one with the dune) that the residents who pay big $ to live there think is a nuisance (and it is)
