Stainless Steel Mooring Line Spring Damper (AISI 316)

This AISI 316 stainless steel mooring spring damper is a heavy-duty solution for secure mooring in all conditions. Engineered for larger boats and harsh marine environments, the spring is made of marine-grade 316 stainless steel, known for its superior corrosion resistance and strength. It works by cushioning sudden loads on your mooring lines – when waves or wind cause the boat to tug, the spring stretches slightly to absorb the impact, reducing stress on ropes, cleats, and anchors. The polished stainless finish not only adds a premium look but also withstands years of exposure to saltwater without rusting. This means long-term reliability for your mooring system and peace of mind when leaving your vessel docked for extended periods.

Key Features:

• Premium AISI 316 Construction – Made from high-grade 316 stainless steel, offering maximum resistance to saltwater corrosion and ensuring long-lasting performance.
• Heavy-Duty Shock Absorption – Robust spring effectively absorbs heavy shocks and tension, ideal for larger vessels or rough weather moorings.
• Protects Equipment – Reduces strain on mooring lines, cleats, and dock hardware, minimizing the risk of line breakage or hardware failure.
• Multiple Sizes for Big Boats – Available in three sizes to accommodate various boat lengths and weights: 70×400 mm (for boats up to ~10 m or 4 tonnes), 90×470 mm (for boats up to ~12 m or 8 tonnes), and 110×470 mm (for boats up to ~14–15 m or 13 tonnes). Choose the appropriate size for your vessel.
• Mirror-Polished Finish – Sleek polished surface that complements your boat’s hardware and prevents snagging or abrasion of lines.

With this stainless mooring line damper, even substantial yachts can be moored more gently and securely. The strength of AISI 316 steel means it can handle significant loads without deforming, making it suitable for heavy displacement boats and frequent use. Install it on your bow and stern lines to ensure smooth, cushioned mooring every time. Especially useful in tidal areas or busy marinas, this stainless steel mooring spring offers top-tier performance and longevity, keeping your investment (and your neighbors’ boats) safe.
