class=\"wp-block-heading\">Enabling Single Fin Dockside Stabilization<\/h1>\n\n\n\n<h3 class=\"wp-block-heading\">Step 1 \u2013 Power On the Stabilizer System<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Power on the Side-Power Stabilizer System using the main control display.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Allow the system to complete initialization and verify there are no active alarms.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2 \u2013 Select Zero Speed Mode<\/h3>\n\n\n\n<p

has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3 \u2013 Enable Limited Stroke<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">When operating alongside a dock, always select <strong>Limited Stroke<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Limited Stroke reduces maximum fin travel, helping prevent excessive fin movement when clearance is limited.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ocean Alexander recommends using Limited Stroke whenever operating Zero Speed Stabilization in a marina environment.<\/p>\n\n\n\n<hr

to:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Home \u2192 Fins<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Select the stabilizer fin nearest the dock and choose:<\/p>\n\n\n\n<p

class=\"wp-block-paragraph\">Observe vessel motion for several minutes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">During single fin operation you should expect:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Noticeable reduction in vessel roll.<\/li>\n\n\n\n<li>Less stabilization than normal two-fin operation.<\/li>\n\n\n\n<li>Safe fin operation away from dock structures.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If excessive vessel motion occurs due to weather or passing vessel wake, discontinue Zero Speed operation if safe stabilization cannot be maintained.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Returning to Normal Operation<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Before leaving the dock:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Exit Zero Speed mode.<\/li>\n\n\n\n<li>Return to the <strong>Fins<\/strong> menu.<\/li>\n\n\n\n<li>Re-enable the disabled fin.<\/li>\n\n\n\n<li>Confirm both fins indicate <strong>Enabled<\/strong>.<\/li>\n\n\n\n<li>Resume normal stabilization before maneuvering away from the berth.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Failure to re-enable both fins before departure will reduce stabilization performance underway.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Best Practices<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">For the safest and most effective dockside operation:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Always operate the fin farthest from the dock.<\/li>\n\n\n\n<li>Use <strong>Limited Stroke<\/strong> whenever clearance is restricted.<\/li>\n\n\n\n<li>Inspect the surrounding area before activating Zero Speed mode.<\/li>\n\n\n\n<li>Never allow mooring lines to pass near operating stabilizer fins.<\/li>\n\n\n\n<li>Periodically verify fin status on the control display.<\/li>\n\n\n\n<li>Disable Zero Speed Stabilization during severe storms if fin movement could create a hazard.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator

class=\"wp-block-paragraph\"><strong>WARNING<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Never operate a stabilizer fin if there is any possibility of contacting a dock, piling, seawall,

By disabling the dockside fin and operating the outboard fin only, operators can continue reducing vessel roll while protecting the stabilizer system from accidental contact with docks, pilings, and surrounding structures. Always return the system to normal dual-fin operation before departing the berth.<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-rich is-provider-embed-handler wp-block-embed-embed-handler wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"SidePower Singe Fin Stabilization\" width=\"1200\" height=\"675\" src=\"https:\/\/www.youtube.com\/embed\/OIQKzaBi-xE?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\"><a href=\"mailto:service@eastcoastyachtgroup.com\">Contact our Service Department today<\/a><br>(954.530.2033)<br>To learn how we can help ensure safe and peak performance for your vessel.<\/p>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\"><strong>East Coast Yacht Group<\/strong><br>2955 West State Road 84<br>Fort Lauderdale, FL 33312<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview The Side-Power Vector Fin Stabilization System allows individual fin control, enabling operators to disable the fin adjacent to the dock while maintaining Zero Speed Stabilization with the opposite fin.
