Diving liveaboard 

A diving liveaboard is a medium to small size cruise boat ( until 150 passengers) on which divers can cruise to diving sites that are often unaccessible to day trip diving cruises.

Our diving liveaboard was definitely the most comfortable way to dive in areas where we were able to see whale sharks, hammer heads, coral reef and beautiful shipwrecks without having to commute to a resort! We spent the whole day diving!

Live-aboard 

Both a noun and a verb, referring to someone who lives aboard a boat, e.g., 'They live aboard their boat' or 'he is a live-aboard'. Can be temporary or permanent, for the length of a dive, vacation, season, lifetime or retirement. If of a more permanent nature, refers to someone who likes the carefree lifestyle associated with living on a boat vs. the responsibility of living in a dwelling on land

One to another: My Dad is retiring soon and he's going to sell his house and become a live-aboard.

Another: No way!

One: Yes, he's going to live-aboard his boat and just sail around the Caribbean and see every single island.

A brain donor would use this word when they actually mean 'live-aboard' - boats, usually for diving, where you live aboard rather than in a hotel.

Hey dude, I was on a really great liverboard out of Sharm.
