When the Nekton Rorqual made its first run to Little
Cayman in early May, local dive operations weren’t
happy. Some claimed that the size of the boat put tremendous
pressure on the reef, saying the height of the
boat “acted like a giant sail,” and the stress resulted in a
broken mooring at Pirates Point Reef. (Wayne Hasson,
who runs the Aggressor Fleet, reminded us that he had
engineered and installed all the buoys around the
Caymans.)
Marine park law only allows the Nekton to take 20
  divers into Bloody Bay and Jackson Point Marine Park,
  but the boat holds 33. To sidestep that limit, the Nekton  has hired a dive boat from McCoy’s resort to carry the
  extra divers. Now, that might abide by the letter of the
  law, but it certainly doesn’t abide by the spirit. After all,
  the law — or regulation — is to keep diver traffic down
  to preserve the pristine underwater environment. If
  Nekton’s approach sticks, what would prevent a cruise
  ship off Little Cayman from dispersing hundreds of
  divers to Bloody Bay Wall – as long as they were in
  boats of 20? We’ve learned that at least one significant
  Cayman official is working to ban the Nekton from Little
  Cayman.
Marc Pothier, who manages Paradise Villas and is
  an executive committee member of the Sister Islands
  Tourism Association, says that dive operators in Cayman
  Brac and Little Cayman have followed these rules for
  years, as has the Cayman Aggressor. “To allow a ‘new business’
  to break the rules would open the door to others
  being able to do the same. Bloody Bay is our only asset.
  We cannot let it be harmed.”
