Boats (sometimes referred to as Floating Boats) was a LEGO System theme that was introduced in 1973 and ran until 2005. 22 sets were released in this theme. The thing that made these sets different from other town sets was the fact that they really did float in water. 1987 saw the introduction of single piece hulls, before then the ships were constructed from 2 or 3 separate hull pieces.
The first sets did not contain any minifigures. 314 Police Launch from 1976 included two LEGOLAND Minifigures. And from 1978, the first set with modern minifigures (709 Police Boat) was released, along with a series of minifigure-compatible sets.
