Step-by-step explanation:
When a boat is pulled out of the water and welding is performed without conducting stability tests or consulting a marine architect, it is a risky and potentially dangerous practice. This procedure is generally referred to as 'hot work' or 'in-water welding without proper preparation.' It disregards important safety measures and can compromise the structural integrity of the boat, leading to accidents or failures.
It is crucial to follow proper procedures and seek professional advice before undertaking any welding or repairs on a boat. Stability tests, consultation with a marine architect, and adherence to safety standards and regulations are essential to ensure the safety and seaworthiness of the vessel.
