Boat maintenance involves regular checks and repairs to ensure a vessel remains safe and functional. This includes inspecting the hull for damage, cleaning the deck, and checking the engine for any issues. Routine tasks like changing the oil, replacing filters, and ensuring the battery is charged are essential for optimal performance. Additionally, maintaining the sails and rigging is crucial for sailing boats. Regularly inspecting and cleaning fenders and lines helps prevent wear and tear. Proper maintenance not only extends the life of the boat but also enhances safety for all on board.
