Captain Hook's Pirate Treasure

You are a young but experienced treasure hunting team, looking for new challenges. And you're in luck: The legendary ship "Seagull" has just washed up in a cove very close to you. According to legend, it only runs aground every 100 years and once belonged to the feared pirate Captain Hook. Supposedly, he hid treasure there, but to this day no one has ever found it. Now you set out to search for Hook's legacy. However, there's a catch: You only have 45 minutes to find the treasure before the tide comes in and pulls the ship into the deep sea. Can you find the treasure in time?
