🧢 Tips for a Great Deep Sea Trip

• Book early if you’re visiting during peak fishing seasons (spring and winter).

• Bring sun protection like a hat, polarized sunglasses, and reef-safe sunscreen.

• Stay hydrated – the offshore sun and salt air can be draining.

• Listen to your crew – they know these waters and can help maximize your success.

• Bring a cooler if you plan to take home your catch. Many charters will fillet your fish dockside.
