It was a 3dcg game. The MC saves the company some money and the female manager is so impressed she invites you onto the CEO's yacht. If I remember correctly she's married to the CEO. The CEO doesn't really care about anything and is just fishing on the opposite side of the boat. Their daughter arrives late and starts swimming in the water. You save her from sharks and I believe you get blown by the manager as a thank you in one of the yacht's rooms.
