The Dive Boats

Neptune & Poseidon

We treat our divers to an uncrowded boat taking out only 8 Divers Max per trip. On our morning and afternoon 2 tank trips we provide an experienced instructor/guide for every dive to help with reef life identification, highlight points of interest or to help with any problem solving. We love to dive so it is fun for us to show you around our beautiful underwater realm. If you'd like, you can buddy up and explore on your own at your leisure. We are computer friendly to allow you longer bottom times.

On our comfortable and well equipped dive boats we have thought of everything to make your dive trip fun, safe and smooth:

• Shade cover
• Comfortable seating
• Locked storage space (no need to lug your gear everyday)
• All rental gear is on board. Need a spare? We have it.
