About LEGO Police Patrol

LEGO Police Patrol (set #4021) is a mid-sized build with 196 pieces from the Boat theme, released in 1991. This is a moderate-level build suitable for ages 8+, with an estimated build time of 1-2 hours. This set dates from the 1990s, a turbulent decade when LEGO launched Star Wars and Mindstorms while navigating financial difficulties.

Set Highlights

  • 196 pieces at moderate complexity — a 1-2 hours build.
  • Compatible with all standard LEGO sets — bricks extend naturally into other sets you own.
  • Play-focused build with interactive elements designed for 8+ builders.
  • Vintage 1991 release — increasingly rare in complete, unplayed condition.

Who Is This Set For?

Gift for Ages 8+

The moderate difficulty makes this accessible without being trivial — a well-matched gift for LEGO fans in the 8+ age range.

Weekend Build Project

196 pieces with an estimated 1-2 hours fits comfortably into a focused afternoon or weekend session.

Expanding a Boat Collection

A solid addition for collectors building out their Boat shelf. Introduces parts and builds that complement other sets from the same line.

Build Tips

1

Check the piece count on the bag against the parts list before starting — knowing what you have prevents mid-build surprises.

2

Even in small sets, connection order matters. Follow the steps rather than building sections independently.

3

Vintage sets may show slight color variation from modern LEGO due to different ABS formulas. This is normal and part of the set's character, not a defect.
