The surfboard rental shop at the beach was happy to create a fresh set of boards for Max and Nico when they arrived and provide hints on the best spots to paddle out to get into the surf that was breaking against the cove.
With physical skills like theirs, he wasn't concerned about them getting hurt or their level of expertise. The Crusader Class Pilots rarely had an issue surfing unless they made a bad judgment call or their body was still recovering from a major injury or cybernetic replacement.
The Cove was part of the private area as well, not open to public surfers to land on unless they wanted to jog down the shoreline to get out of the resort's portion of the beach.
For that reason, anyone who surfed there was considered a bit of an elitist, and the waves were empty.
