It's safer to wear it

Valerie shook herself out of her train of thought. What in the world was she thinking? This was her first mission back, and a chance to show her agency that she could still get the job done. She needed to be professional and follow her mission plan as much as she could.

She put on the wetsuit, closing the zipper shut and making sure it was snug. The rubber felt cold to the touch, but it would protect her from the colder ocean water. She fastened the pouch around her thigh, put on the scuba mask on her face, and slung the small air cylinder on her back.

She took a final look around to see if everything was as it should be, and then dived into the water.

She immediately felt the coldness of the water around her, especially on her bare legs. She was thankful she had decided to wear the suit. She swam in the direction of the vessel, reaching it without much incident. Quietly, she raised her head over the surface of the water.

Everything was dead silent. Quietly, she grabbed the ladder on the side of the yacht, climbing to the upper deck. She carefully scanned her surroundings - there was nobody around.

She quietly took off her mask and air cylinder, noiselessly placing it near the walls. She would retrieve them on her way out. She remembered the plans of the ship she had seen in her briefing - the memory module was supposed to be in a small safe located in the center room.

She tiptoed her way to the door in front of her. To her surprise, it was ajar - likely the result of someone wanting to feel the cool ocean breeze as they slept. She quietly opened it just enough to sneak in, entering the vessel.
