A
yacht party is a party that is held on a yacht. A boat party is a party that is held on a boat. The two are not the same thing.
A yacht party is a luxurious affair. It is usually hosted by wealthy people and attended by their equally wealthy friends. A typical yacht party will have champagne, caviar, and other expensive food and drink options. There will also be a DJ or live band playing music to keep the guests entertained.
A boat party, on the other hand, can be held on any type of boat - from a small rowboat to a large cruiseship. The atmosphere of a boat party will depend on the type of boat it is being held on. A small rowboat might have a more intimate setting with just close friends, while a cruiseship might have hundreds or even thousands of people attending.
