Final answer:
The phrase 'still use floaties' suggests that Ross is not confident in his swimming abilities without the help of swimming aids, indicating Ross's use of swimming aids as the correct answer.
Step-by-step explanation:
Based on the context given, the best fit for what Ross's statement about still using "floaties" reveals about him is Ross's use of swimming aids. The phrase suggests that he is not yet confident in his swimming abilities without the assistance of flotation devices. This fits into a broader narrative theme exploring the concept of human vulnerability and insecurities, especially in the face of nature's overwhelming power as depicted in the text provided. Whether facing the sea's swashing waves or rowing amidst rolling billows, the characters in the narratives express a level of discomfort or fear that leads them to rely on various forms of support, be it physical swimming aids or the psychological comfort of believing one is closer to shore.
The excerpts from the text given do not indicate a proficient expertise in rowing, and although floating devices are used, the focus is not on a passion for them, but rather on the necessity due to the characters' situations at sea. There is a palpable tension between the characters' desire to survive and the mercilessness of the ocean, leading to the reliance on life-preservers and other aids.
