Picture from installation on Sadler 34 with a foam core hull construction<\/p><\/div>\n

Ultrasonic transducers must make direct contact with the outer skin of the hull. For hulls constructed with a foam sandwich or other core, a small area of this material must be removed to expose the outer skin.<\/p>\n

A 150mm (6″) diameter cut out (approx) is recommended as this will allow room to prepare a flat and smooth surface before bonding the transducer ring. The cut edge should be sealed with a gel wash coat or epoxy based filler to prevent water ingress.<\/p>\n

It is recommended that this type of installation is carried out when the boat is out of the water.<\/p>\n","protected":false},"excerpt":{"rendered":"
