Is LEGO Hydroplane Racer retired?

What is the price per piece for Hydroplane Racer?
At its $20 retail price across 180 pieces, Hydroplane Racer works out to about $0.111 per piece. Collectors often use price per piece to judge whether a set is good value.
Is LEGO Hydroplane Racer a good investment?
Hydroplane Racer currently trades 64.1% above its $20 retail price, and it is retired, so no new supply is entering the market. Past performance is not a prediction — condition, packaging and how long you hold all affect what a set actually sells for. BrickStats reports the numbers rather than giving investment advice.
Why is LEGO Hydroplane Racer so expensive?
Hydroplane Racer was released in 2015 and has since retired. Once LEGO stops producing a set, the only supply is what is already in circulation, so sealed copies in good condition compete for a shrinking pool of stock. That scarcity, not the parts, is what moves the price.
