This essentially depends on the areas in which you sail and their level of wear.<br \/>\nAluminum anodes are less polluting than zinc or magnesium anodes, offering excellent protection for aluminum hulls and equipment.<br \/>\n<em>ATTENTION: an anode loses its effectiveness when it is more than 60% worn &#8211; Aluminum anodes in seawater \/ Magnesium anodes are preferable in freshwater. <\/em><\/p>\n<p>In the light of our experience and to limit galvanic corrosion (which is normal), when your boat is docked and only in this case, you can lower the platform so that the end of the column touches the water. This allows galvanic current to escape from the system into the sea, thus limiting corrosion. Simply lower the platform so that the &#8220;first deployment section&#8221; of the system touches the water, without the platform support arms necessarily touching the water.<br \/>\nOn the other hand, if you leave the platform in the air (fully retracted), galvanic current does not easily escape from the columns and tends to &#8220;accelerate&#8221; corrosion of the anodes and the system.<\/p>\n<h3>Equipped boats<\/h3>\n<ul>\n<li>Fountaine Pajot : <strong><a title=\"ASTREA 42\" href=\"https:\/\/www.catamarans-fountaine-pajot.com\/en\/astrea-42\/\" target=\"_blank\" rel=\"noopener\">ASTREA 42<\/a><\/strong>, <strong><a title=\"ELBA 45\" href=\"https:\/\/www.catamarans-fountaine-pajot.com\/en\/sailing-catamarans\/catamaran-elba-45\/\" target=\"_blank\" rel=\"noopener\">ELBA 45<\/a><\/strong><\/li>\n<li>Prestige : <strong><a title=\"Prestige F4\" href=\"https:\/\/www.prestige-yachts.com\/yachts\/1-f-line\/119-f4-3\" target=\"_blank\" rel=\"noopener\">F4<\/a><\/strong> (hydraulic version)<strong>, <a title=\"Prestige M48\" href=\"https:\/\/www.prestige-yachts.com\/yachts\/5-m-line\/112-m48\" target=\"_blank\" rel=\"noopener\">M48<\/a><\/strong><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>The <strong>NL3621 sacrificial anode kit<\/strong> is designed to protect the lifting systems of bathing platforms and tender supports on boats.<\/p>\n<p>Compatible with <strong>NOVAL<\/strong> aluminum lifting columns, this kit includes four rectangular anodes and eight A4 M6x16 TCHC stainless steel screws.<\/p>\n<p><strong>Technical documentation accompanies the product<\/strong> to facilitate installation and maintenance, which is possible directly from the water on three-stage systems.<br \/>\nAnodes should be inspected annually and changed every 12 months, depending on the sailing environment.<\/p>\n<p>When parked for long periods, <strong>lowering the platform<\/strong> and placing it in contact with the water will <strong>limit galvanic corrosion<\/strong> of the system.<\/p>\n","protected":false},"featured_media":3181,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[122,93],"product_tag":[1241,423,1242,1243],"class_list":["post-2898","product","type-product","status-publish","has-post-thumbnail","product_cat-mechanical","product_cat-spare-parts","product_tag-anodes-2","product_tag-noval-2","product_tag-platform-2","product_tag-spare-parts-2","product_shipping_class-small-2","first","instock","sale","featured","downloadable","taxable","shipping-taxable","purchasable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/nauticspares.com\/en\/wp-json\/wp\/v2\/product\/2898","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nauticspares.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/nauticspares.com\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/nauticspares.com\/en\/wp-json\/wp\/v2\/comments?post=2898"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/nauticspares.com\/en\/wp-json\/wp\/v2\/media\/3181"}],"wp:attachment":[{"href":"https:\/\/nauticspares.com\/en\/wp-json\/wp\/v2\/media?parent=2898"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/nauticspares.com\/en\/wp-json\/wp\/v2\/product_brand?post=2898"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/nauticspares.com\/en\/wp-json\/wp\/v2\/product_cat?post=2898"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/nauticspares.com\/en\/wp-json\/wp\/v2\/product_tag?post=2898"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
