Unlike submarines, submersibles like this underwater drone for exploring the ocean, finding fish, corals, and other sea creatures, need to be supported by a larger watercraft like this paddleboard.

Combining a paddleboat or kayak with a submersible is a perfect way to explore the depths of the oceans of Sentosa. The waters were rough, you can't tell because of the stabilisation on my DJI Action camera, but the paddle board was able to handle the choppy and heavy waves well.
