Hull-attached thermometers provide a very convenient and accurate means of measuring sea- surface temperature. They are necessarily distant-reading devices, the sensor being mounted either externally in direct contact with the sea using a "through-the-hull” connection, or internally (the “limpet” type) attached to the inside of the hull. Both types show very good mutual agreement, with the ”through-the-hull” type showing a slightly quicker response.
