The Scuba Diving Earth Luxury Rating (SDE Lux Rating) is explained on each liveaboard review when you click the “Discover Liveaboard” link, and is my own Liveaboard Luxury Rating I’ve assigned to all liveaboards. Choosing between liveaboards is helped by customer scores, and if you get stuck choosing between two or three liveaboards, where each one has a high customer score out of 10, you can use the SDE Luxury Rating to help narrow down your choice.

Think about it like using when searching for the best hotel. also use a customer score where each customer rates hotels out of 10. This is similar to the liveaboard customer rating, which is also rated out of 10. But let’s say you only like to stay in hotels rated 8 and above on, but you also want the hotel to have WIFI or parking, or to have a swimming pool etc. The features each hotel has is usually secondary to the score out of 10.

How long does it take for bones to decompose in the ocean?

Once a human body has been skeletonized after the scavenging animals have removed the fleshy parts, the bones may undergo fossilization in salty sea water. Fossilization is when the bones are converted into minerals. This means the bones may last indefinitely at Truk Lagoon.
