<p>A device which can guide a vessel toward, or maintain a vessel within, water having a nominated temperature range, e.g. 17-18oC. Sensors (5) and (6) continuously measure the temperature of the water at opposite sides of the vessel which temperatures are displayed at (9) and (10). Controller (2) monitors these temperatures until the desired range of temperature, as set by switch (11) is reached. This is indicated by warning light (12) and sound (13). Switch (16) is then placed on automatic to steer the boat within the nominated temperature range of (11). This steering is carried out by connecting the signal output (17) onto the rudder of the vessel. The direction of vessel movement towards the required temperature range is indicated by meter (20) and lights (14) and (15).</p> |
