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 Booking.com when searching for the best hotel. Booking.com 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 Booking.com, 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.
