What is hull ga?

Hull ga refers to the measurement of the hull thickness or strength of a ship or boat. The hull is the main body of a vessel, typically made from metal, fiberglass, or wood, that provides structural support and protection against water and other external elements.

A hull ga survey involves inspecting and measuring the thickness of the hull material to ensure it meets safety standards and is in good condition for use. This is important to prevent water leakage, corrosion, and structural weaknesses that could compromise the integrity of the vessel.

Regular hull ga inspections are typically conducted by trained professionals using specialized equipment such as ultrasonic thickness gauges to measure the thickness of the hull material accurately. These inspections are essential for ensuring the safety and seaworthiness of a ship or boat.
