Watertight Flashlight
Most craft are required to carry one watertight flashlight onboard at all times. In an emergency, a flashlight can be used for illumination or to send a distress signal. To be approved, the batteries must be in good condition. A watertight flashlight qualifies as navigation lights on non-powered vessels less than 7 m in length.
You can signal your need for help by flashing S.O.S using three short flashes, then three long flashes, followed by three short flashes.
