A visual aid for boat skippers to which a skipper inputs information about the relative position of another observed boat and a navigation light color which he observes. The device has a group of input switches each indicating a possible relative position of the second boat. Another group of switches indicates the possible navigation light colors of red, green and white. A display signals whether the input combination of position and lights is a potential collision condition. A collision detecting logic circuit connects the switches to a display for actuating the display in response to actuation of selected combinations of the switches.

An auxiliary mirror attachment unit for mounting on a primary mirror is provided having a support housing and an optical reflecting element assembled with the housing. The support housing includes an integrally formed base plate and a peripheral wall projecting laterally from the plate. The reflecting element is of plate form having a peripheral edge of a configuration to interfit with the housing's peripheral wall. Mechanical interlocking of the reflecting element with the housing in assembled relationship is effected by cooperatively interfitting tongue and groove conformations formed on the respective peripheral edge of the reflecting element and on an inwardly facing surface of the peripheral wall. The support housing is formed from a material having a minimum degree of resilience to enable mechanical assembly with the reflecting element. Attachment of the unit to a primary mirror is accomplished by adhesive.
