Problem:

To cool down the driver and passengers without introducing a full air conditioning system  

Ideation:

Ideas	Sketches(If any )	Explanation
Dark interior		Dark colours, such as black are absorbs light really well and does not reflect it back. If sunlight is shown through the windows, instead of the heat bouncing off bright colours and creating a greenhouse effect inside the cabin, dark coloured materials may reduce that effect and lower temperatures inside cabin.
Water Cooling		Run tubes filled with water along the seats of the driver and passengers. The tubes will be connected to a central system and would run out side the car attached to a radiator and pump. To be efficient, no fans would cool the radiator. Instead, the air around it as the car moves will.
Thin meshed seats		A normal car seat is usually made of leather or a spongy suede material. When a person sits, their entire back is pressed against it and insulating the heat the body produce. I meshed seat would allow the back to "breathe" and allow heat to escape.
Air Vents	Vent slot through the catamaran?	To maximize battery efficiency, instead of having electric fans blow onto occupants, a vent created through the catamaran in the middle can provide cool airflow into the cabin cooling everyone and promoting sweat evaporation.
Ventilation through seat		To have direct contact with the passenger and could help with cooling the passenger down.
