What this video covers
A professional surveyor performs an ultrasonic inspection on the hull of the 36-ft sailboat Uma to assess structural integrity and identify areas of delamination.5:19 The process involves using an ultrasonic device to measure hull thickness and detect internal voids or separations within the fiberglass laminate, which are invisible to the naked eye.3:10 The surveyor maps the hull, finding thicknesses ranging from 7mm to 11mm, and confirms that while the boat is structurally sound, two critical areas—the chainplate attachments and the structural knees—require reinforcement to prevent future fractures.16:10 The inspection reveals that the delamination in the knees extends two-thirds of the way up, significantly further than the owners previously estimated.17:34 The surveyor recommends a specific lamination schedule to transition stiffness between reinforced sections and the flexible hull, preventing the creation of new hard points.16:10 This diagnostic step allows the crew to proceed with their interior refit and hull reinforcement plan with professional guidance.17:51
