He became a navigator\u2014the person responsible for trajectory and weather\u2014on racing sailboats. Later, he transitioned to being a router (the land-based equivalent of a navigator) and has been practicing this profession for thirty years. <\/b><\/p>\n<p><b>Christian Dumard, what is the purpose of routing for a rower?<\/b><\/p>\n<p>It\u2019s about planning routes, anticipating what might happen, and minimizing exposure to risks:<\/p>\n<p>Beyond performance, the priority is to arrive safely without breaking everything. When embarking on a 120-day ocean crossing, you can&#8217;t predict what will happen beyond ten days. This is especially true for a rower because, if a large boat loses its mast, it will still float. But a rower can quickly be in danger.    <\/p>\n<p>Routing is also about optimization\u2014finding the best compromise: <\/p>\n<p>Since rowing boats are slow, it&#8217;s crucial to align with ocean currents, as they help maintain movement 24\/7, even though rowing is only done for eight hours per day. However, the route shouldn&#8217;t be excessively lengthened just to catch the current. <\/p>\n<p><b>What motivated you to join this adventure?<\/b><\/p>\n<p>I love unique and unconventional projects\u2014they are engaging. When routing a boat crossing the Atlantic, the journey lasts about 15 days, and once it arrives, the project is over. But Louis has been on his journey for nearly a year and a half! This creates bonds, and we feel more involved in the adventure. What\u2019s great is that we also got to discuss the route together.     <\/p>\n<p><b>Speaking of the route, how did you choose it?<\/b><\/p>\n<p>We conducted a climatological study of past years&#8217; conditions along different routes to assess wind strength and sea state. Based on these factors, we chose a specific route. However, plans evolved\u2014we initially considered the North Pacific route. Over time, we realized that if Louis arrived in Central America with strong winds, he might not be able to stop and could end up stranded on a beach with his boat looted. That wasn\u2019t ideal. Colombia turned out to be a better choice\u2014it was also a shorter rowing distance. [\u2026] There was still a risk of missing Colombia, but several ports were available along the way. Additionally, the wind was parallel to the coast, making it less dangerous.       <\/p>\n<p><b>How does Louis Margot receive your information?<\/b><\/p>\n<p>Since he has Starlink [satellite internet provider] on board, a platform shows him the proposed route. When conditions change significantly\u2014such as after departing from Portugal or between the Caribbean and Colombia\u2014we send him a daily analysis and communicate via video.  <\/p>\n<p>During the Pacific crossing, updates are sent every two to three days since conditions are relatively stable and monotonous. When he&#8217;s about 15 days away from the Marquesas Islands, we\u2019ll switch back to daily updates to help him target the islands and make key decisions: Should he stop in the Marquesas? Would another current make it better to continue further?   <\/p>\n<\/p>\n<p><b>What dangers might he encounter at sea?<\/b><\/p>\n<p>A solo boat always faces the risk of collision, regardless of the type of vessel. However, he has a beacon that continuously transmits his location, making him visible to other boats.<br \/>There are also risks of injuries or skin issues. The biggest concern, however, is the boat capsizing due to bad weather.   <\/p>\n<p><b>After departing across the Atlantic, Louis returned to Portugal. How was that decision made? <\/b><\/p>\n<p>When he left, the conditions were borderline. We had set limits that we didn\u2019t want to exceed\u2014if I recall correctly, no more than 20 knots of wind [37 km\/h], 3-meter waves, and a maximum number of days spent attached to a sea anchor.<br \/>Conditions deteriorated slightly, and we quickly saw that those limits had been reached. The decision to turn back was made quite naturally.    <\/p>\n<div> <\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-9b3afa3 elementor-widget elementor-widget-text-editor\" data-id=\"9b3afa3\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><strong>Article : <\/strong><a href=\"https:\/\/www.linkedin.com\/in\/j%C3%A9r%C3%B4me-laurent-39622b2a0\/\">J\u00e9r\u00f4me Laurent<\/a><\/p>\n<p>In collabation with<a href=\"http:\/\/www.journaldemorges.ch\">Journal de Morges<\/a><\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-aad0a14 elementor-widget elementor-widget-heading\" data-id=\"aad0a14\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">Share !<\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5ecf9cf elementor-share-buttons--view-icon elementor-share-buttons--skin-minimal elementor-share-buttons--shape-circle elementor-grid-0 elementor-share-buttons--color-official elementor-widget elementor-widget-share-buttons\" data-id=\"5ecf9cf\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"share-buttons.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-grid\" role=\"list\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-grid-item\" role=\"listitem\">\n\t\t\t\t\t\t<div class=\"elementor-share-btn elementor-share-btn_facebook\" role=\"button\" tabindex=\"0\" aria-label=\"Share on facebook\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-share-btn__icon\">\n\t\t\t\t\t\t\t\t<i class=\"fab fa-facebook\" aria-hidden=\"true\"><\/i>\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-grid-item\" role=\"listitem\">\n\t\t\t\t\t\t<div class=\"elementor-share-btn elementor-share-btn_twitter\" role=\"button\" tabindex=\"0\" aria-label=\"Share on twitter\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-share-btn__icon\">\n\t\t\t\t\t\t\t\t<i class=\"fab fa-twitter\" aria-hidden=\"true\"><\/i>\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-grid-item\" role=\"listitem\">\n\t\t\t\t\t\t<div class=\"elementor-share-btn elementor-share-btn_linkedin\" role=\"button\" tabindex=\"0\" aria-label=\"Share on linkedin\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-share-btn__icon\">\n\t\t\t\t\t\t\t\t<i class=\"fab fa-linkedin\" aria-hidden=\"true\"><\/i>\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-grid-item\" role=\"listitem\">\n\t\t\t\t\t\t<div class=\"elementor-share-btn elementor-share-btn_whatsapp\" role=\"button\" tabindex=\"0\" aria-label=\"Share on whatsapp\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-share-btn__icon\">\n\t\t\t\t\t\t\t\t<i class=\"fab fa-whatsapp\" aria-hidden=\"true\"><\/i>\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-grid-item\" role=\"listitem\">\n\t\t\t\t\t\t<div class=\"elementor-share-btn elementor-share-btn_email\" role=\"button\" tabindex=\"0\" aria-label=\"Share on email\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-share-btn__icon\">\n\t\t\t\t\t\t\t\t<i class=\"fas fa-envelope\" aria-hidden=\"true\"><\/i>\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Since the beginning of the Human Impulse adventure, Christian Dumard has been routing Louis Margot while he is at sea.
