I took a Crystal Kayak out for a test drive to see how it might work on board some of the ships. This clear kayak was neat to paddle as it was completely see through. Paddling it in protected mangroves in calm seas was very fun. I saw plenty of the upside-down jellies (Cassiopea sp) and other mangrove species. It was nice to get out for a paddle while I was between trips in Florida. The mangrove channels have lots of fun twists and turns!
