This guide explores Mayday Calls and Distress Signals and explains how to make a proper call, the importance of distress signals, and the gear every boater should carry to ensure the best chance of rescue.<\/p>\n\n\n\n<div style=\"height:12px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>What Is a Mayday Call?<\/strong><\/p>\n\n\n\n<p>A Mayday call is the most urgent distress message in marine radio communication. It\u2019s used only in life-threatening situations when you or your vessel are in grave and imminent danger, such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Your boat is sinking or has capsized<\/li>\n\n\n\n<li>There\u2019s a fire aboard<\/li>\n\n\n\n<li>Someone has gone overboard<\/li>\n\n\n\n<li>A serious injury or medical emergency has occurred<\/li>\n\n\n\n<li>You\u2019ve collided or run aground in hazardous conditions<\/li>\n<\/ul>\n\n\n\n<p>Misusing a Mayday is not only irresponsible, but also a criminal offence under maritime law, as it can delay real rescues. Always be certain that lives are truly at risk before making the call.<\/p>\n\n\n\n<div style=\"height:12px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>How to Make a Mayday Call<\/strong><\/p>\n\n\n\n<p>Use your <a href=\"https:\/\/oceansignal.com\/products\/v200\/\">VHF marine radio<\/a> on Channel 16, which is monitored continuously by <a href=\"https:\/\/hmcoastguard.uk\/\">HM Coastguard<\/a> and other vessels in your vicinity.<\/p>\n\n\n\n<div style=\"height:12px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>Format for a Mayday Call:<\/strong><\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li>Say \u201cMayday, Mayday, Mayday\u201d<\/li>\n\n\n\n<li>State the name of your vessel three times<\/li>\n\n\n\n<li>Give your position (preferably latitude\/longitude or a bearing from a known point)<\/li>\n\n\n\n<li>State the nature of the emergency<\/li>\n\n\n\n<li>Say how many people are on board<\/li>\n\n\n\n<li>Include any other vital details, such as injuries or description of the vessel<\/li>\n\n\n\n<li>End the call with \u201cOver\u201d, then stand by for a response<\/li>\n<\/ol>\n\n\n\n<div style=\"height:12px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>Recognized Distress Signals<\/strong><\/p>\n\n\n\n<p>If you need to reinforce your call for help, there are several internationally recognised distress signals that can be used, both visual and audible.<\/p>\n\n\n\n<div style=\"height:12px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>Visual Distress Signals:<\/strong><\/p>\n\n\n\n<div style=\"height:12px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>Daylight:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Distress flag (orange with a black square over a black circle)<\/li>\n\n\n\n<li>Orange smoke flares<\/li>\n\n\n\n<li>Signal mirror to reflect sunlight<\/li>\n<\/ul>\n\n\n\n<div style=\"height:12px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>Night-time:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/oceansignal.com\/products\/edf2-electronic-distress-flare\/\">Electronic Visual Distress Signal Devices<\/a> (eVDSD)<\/li>\n\n\n\n<li>Red rocket flares or parachute flares<\/li>\n\n\n\n<li>Red handheld flares<\/li>\n<\/ul>\n\n\n\n<div style=\"height:12px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>Audible &amp; Other Signals:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Repeatedly waving your arms slowly up and down<\/li>\n\n\n\n<li>Sound signals: prolonged blasts on a foghorn or bell<\/li>\n\n\n\n<li>SOS in Morse code: &#8230; &#8212; &#8230; via light or sound<\/li>\n\n\n\n<li>Dye markers in the water (visible from the air)<\/li>\n<\/ul>\n\n\n\n<div style=\"height:12px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>Modern technology has significantly increased the chances of swift rescue in an emergency.

Whether you\u2019re venturing just offshore or crossing the North Sea, ensuring a thorough understanding of mayday calls and distress signals, and thereby having the ability to communicate distress properly, is part of being a responsible skipper or crew member. Safety at sea begins with preparation and ends with communication.
