It can be mounted directly onto the deck, console, or between the seat and a standard-size pedestal. With its simple weight adjustment system using EPDM shims, the VLF provides superior shock absorption without the need for tools.<\/p>\n<p>Already widely used on motorboats worldwide, the 4S suspension solutions are now <strong>available in Europe<\/strong>, offering an <strong>affordable<\/strong> and effective way to <strong>improve comfort, safety<\/strong>, and durability at sea.<\/p>\n<p>This semi-suspension unit is also equipped with <strong>a clever tilting system<\/strong> that allows the seat to be folded forward. When the boat is at dock or anchor, this <strong>prevents the seat from filling with water<\/strong>. It also offers <strong>practical access to a hatch<\/strong> or equipment located under the suspension, making it both functional and space-efficient.<\/p>\n<h2>Specifications<\/h2>\n<ul>\n<li><strong>Height:<\/strong> 60 mm (2.5&#8243;)<\/li>\n<li><strong>Adjustable preload:<\/strong> 50\u2013130 kg (110\u2013285 lbs)<\/li>\n<li><strong>Weight:<\/strong> 4 kg (9 lbs)<\/li>\n<li><strong>Deck mount:<\/strong> 330 \u00d7 230 mm (13 \u00d7 9&#8243;)<\/li>\n<li><strong>Seat mount:<\/strong> 330 \u00d7 315 mm (13 \u00d7 12.5&#8243;) \u2013 handles 250 mm (10&#8243;) from center line<\/li>\n<li><strong>Materials:<\/strong> Premium marine-grade stainless steel, aluminium, EPDM<\/li>\n<li><strong>Standards:<\/strong> Meets ABYC H-31 requirements for type AO (any boat, any position, any speed)<\/li>\n<\/ul>\n<h2>Installation \/ Maintenance<\/h2>\n<h3>Installation<\/h3>\n<p>Quick and easy to install, the <strong>VLF semi-suspension<\/strong> unit can be fitted directly onto the deck or between the seat and a pedestal.
