42045

LEGO Technic set 42045 Hydroplane Racer depicts a racing hydroplane, using the mechanical building style associated with the Technic theme. Released in 2016, it contains 180 pieces and includes no minifigures.

Set 42045 belongs to LEGO Technic and focuses on a water racing subject rather than a road vehicle. Its hydroplane form gives it a distinct place within the theme, where many sets explore machines, vehicles and visible construction techniques. The model is best understood as a compact Technic interpretation of a fast racing boat.

The set contains 180 pieces and no named characters or minifigures. Its build uses Technic parts to establish the hull, cockpit area and low racing profile associated with the subject. Since no confirmed information about specific mechanical functions is provided, the set should be described in general construction terms rather than with unverified features.

Hydroplane Racer suits builders who want a smaller Technic model with a nautical racing theme. As a display piece, it offers a compact vehicle shape. In a Technic collection, it adds variety by representing water speed rather than land transport, while still fitting the theme’s emphasis on structure and mechanical presentation.
