With the exception of water bottles with screw lids, we kindly request that you do not bring food or beverages onto the vessel. Bring your sunglasses or a hat / cap, you will appreciate them when you disembark! Regarding digital cameras, we highly recommend that you make sure your camera battery is fully charged, that you have plenty of space on your SD cards or that you bring a back-up SD card. Due to the ambient lighting inside the vessel, an underwater or low lighting setting is recommend. We also recommend that you disengage the flash, as it may bounce against the windows and take a photograph of your face! Please be careful of sharp objects (watches, jewelry, cameras etc) against the windows. We want to avoid those nasty scratches!
