In future chapters, later on, we will deal with other headsails such as the spinnaker or asymmetric sails.<\/span><\/p>\n<p><span style=\"color: rgba(0, 0, 0, 0.95);\">To do so, we will see the four control elements that we have on this headsail, which we can see in the figure, and some notions of how to act on them in different wind conditions.<\/span><\/p>\n<p><span style=\"color: rgba(0, 0, 0, 0.95);\">These control elements on which we can act on a headsail (genoa or jib) are:<\/span><\/p>\n<p style=\"padding-left: 40px;\" align=\"left\"><span style=\"color: rgba(0, 0, 0, 0.95);\">&#8211; the tension of the forestay,<\/span><br \/><span style=\"color: rgba(0, 0, 0, 0.95);\">&#8211; the tension of the halyard with which we hoist the sail,<\/span><br \/><span style=\"color: rgba(0, 0, 0, 0.95);\">&#8211; the position of the sheet traveller,<\/span><br \/><span style=\"color: rgba(0, 0, 0, 0.95);\">&#8211; and the tension with which we take in the sheet.<\/span><\/p>\n<p align=\"left\"><span style=\"color: rgba(0, 0, 0, 0.95);\">-We will, however, leave for the next chapter how to use the sail indicators (the telltales), which will help us to act on these control elements for fine-tuning the trim.<\/span><\/p>\n<p align=\"left\"><img decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/navegantesoceanicos.com\/wp-content\/uploads\/2020\/03\/Foresail-controls.png\" alt=\"\" width=\"468\" height=\"661\" \/><\/p>\n<h2 style=\"text-align: center;\" align=\"justify\"><span style=\"text-decoration: underline; font-size: x-large;\"><span style=\"font-family: Amaranth; font-weight: normal;\"><strong><span style=\"color: #0003bf; text-decoration: underline;\"><div class=\"ihc-locker-wrap\"><div  class='ihc_locker_3'><div  class='lk_wrapper'><\/div><div class='lock_content'><h2>Este contenido solo est\u00e1 disponible para subscriptores de navegantesoceanicos.com<\/h2>\n<p>Efec\u00fae <strong>Log In<\/strong> para desbloquear.<\/p>\n<\/div><div class='lock_buttons'>\n  <!-- Login Form - Start -->\n  <div class=\"ihc-login-form-wrap ihc-login-template-9\">\n      <form method=\"post\" id=\"ihc_login_form\">\n          <input type=\"hidden\" name=\"ihcaction\" value=\"login\" \/>\n          <input type=\"hidden\" name=\"ihc_login_nonce\" value=\"0ca7d4f102\" \/>\n\n          \n                    <!-- Username field -->\n          <div class=\"impu-form-line-fr\">\n              <i class=\"fa-ihc fa-username-ihc\"><\/i>\n              <input type=\"text\" value=\"\" name=\"log\" id=\"iump_login_username\" placeholder=\"Username\"\/>\n          <\/div>\n          <!-- End of username field -->\n          \n                    <!-- Password field -->\n          <div class=\"impu-form-line-fr\">\n              <i class=\"fa-ihc fa-pass-ihc\"><\/i>\n              <input type=\"password\" value=\"\" name=\"pwd\" id=\"iump_login_password\" placeholder=\"Password\"\/>\n              <span  class=\"ihc-hide-login-pw hide-if-no-js\" data-toggle=\"0\" aria-label=\"Show password\">\n              <span class=\"dashicons dashicons-visibility\" aria-hidden=\"true\"><\/span>\n                <\/span>\n          <\/div>\n          <!-- End of Password field -->\n          \n          \n          <!-- Remember me checkbox -->\n                    <div class=\"impu-remember-wrapper\">\n              <input type=\"checkbox\" value=\"forever\" name=\"rememberme\" class=\"impu-form-input-remember\" \/>\n              <span class=\"impu-form-label-fr impu-form-label-remember\">Remember Me<\/span>\n          <\/div>\n                    <!-- End of remember me --->\n\n                        <div class=\"impu-form-links-pass\"><a href=\"https:\/\/navegantesoceanicos.com\/iump-reset-password\/\">Lost your password?<\/a><\/div>\n          \n          <div class=\"ihc-clear\"><\/div>\n\n          <!-- captcha -->\n                    <!-- end of captcha -->\n\n          <!-- Submit bttn -->\n                        <div class=\"impu-form-line-fr impu-form-submit\">\n                  <input type=\"submit\" value=\"Log In\" name=\"Submit\"  class=\"button button-primary button-large\"\/>\n              <\/div>\n                    <!-- End of Submit bttn -->\n\n          <!-- Social -->\n                    <!-- End of Social -->\n\n          <!-- Additional links -->\n                        <div class=\"impu-form-links\">\n                  <div class=\"impu-form-links-reg\">Don&#039;t have an account?
