Don't be deceived by the pristine white image of the Coral Discoverer as seen on their web site, likewise the Coral Xplorer. This ship is showing it's age - due for a much needed refit in the near future I believe. The present grey/white external livery does nothing to make you feel a buzz of pride when you first board her. Rust patches appear all over and the metal work is far from shiny. The sun deck is unusable in the tropics as there is no shade to go with the 9 or so old sun beds and 15 plastic chairs & tables. The wonderful standard of the seafood buffet presented on the first night was not maintained and after 3 weeks cruising many items had disappeared from the rations. The laundry next to useless and the bed linen only changed once a week.
On the plus side - if the Coral Discoverer happens to be going where and when you want to go then she is not unusable. The young crew (understaffed) worked tirelessly to please, the cabins are acceptable, the food school dinners and the hot water plentiful. Be warned that should you cross the equator our Captain thought it a good laugh to pay homage to King Neptune by ladling sloppy fish soup over the heads of the passengers. An amazing exhibit of power over the embarrassed made all the more astonishing by the fact that most of the guests accepted it!
We visited Papua New Guinea and the Indonesian part of the island, up to the equator for a total eclipse of the sun which they got spot on, then back down through the Spice Islands to Darwin. Ten out of ten for the itinerary but sadly not matched by the boat though this was an expensive expedition. If you risk it - B deck is less expensive and better than A deck.
Dull but OK. Good supply of hot water when needed. Bed linen changed only once a week. B deck cheaper and better than A deck.
