The atmosphere on board the Aqua Cat is always relaxed and casual. You’ll spend your days in bathing suits and casual wear.Ê Bring shorts or pants, T-shirts and a windbreaker. Also bring a pair of sandals, hat, sunscreen (reef-safe) and sunglasses. In winter, a sweatshirt or sweater is advisable. Our ship’s boutique offers shirts, rash guards, mugs, hats and toiletries.
