- Custom lengths are easily made with proper hardware.
We supply marine grade bungee cords, offering a wide range of high-quality shock cords for boats. Our inventory includes various diameters, colors, and strengths to meet all your marine needs. We also stock essential accessories like bungee cord hooks, crimps, and clips, allowing you to create custom lengths for your specific applications.
What Is Marine Grade Bungee Cord?
Marine grade bungee cord—also referred to as marine shock cord—is built to perform in wet, sun-exposed, and high-movement environments. It consists of an elastic core protected by a woven outer sheath.
Common sheath materials include cotton, polypropylene, and Dacron polyester. These materials help the cord resist moisture, ultraviolet exposure, and routine abrasion encountered onboard.
Common Applications Onboard
Marine grade bungee cords are used wherever controlled stretch and secure tension are required on a vessel.
- Securing boat covers: Keeps covers in place during wind and motion.
- Holding down equipment: Stabilizes coolers, tackle boxes, and deck gear.
- Storing sails and canvas: Bundles fabric neatly when not in use.
- Attaching fenders: Provides adjustable, shock-absorbing dock protection.
- Tarps and shades: Supports flexible mounting of sun and weather covers.
Shock Cord Accessories
To support custom installations and repairs, we also stock hardware designed for use with marine shock cord.
- Bungee cord hooks: Create secure attachment points.
- Crimps and clips: Allow precise length customization.
- Shock cord hardware: Supports a variety of rigging setups.
Frequently Asked Questions
What is marine-grade shock cord?
Marine-grade shock cord is a bungee-style rope with a latex or rubber core and a polyester or polypropylene outer sheath. It is designed to resist UV exposure, saltwater, and abrasion for extended use on boats.
What materials are used to make marine-grade shock cord?
Marine-grade shock cord consists of a highly elastic rubber core protected by a durable outer sheath. While some covers use cotton or polypropylene, premium marine versions often utilize Dacron polyester, which is preferred for its superior resistance to UV radiation, moisture absorption, and salt-air degradation.
How do I choose the right diameter for my application?
The diameter determines the cord's strength and resistance to stretching. Thinner diameters (1/8" to 3/16") are typically used for lightweight tasks like sail ties or securing small gear. Thicker diameters (1/4" and up) offer higher tension and are better suited for heavy-duty applications such as securing boat covers or attaching large fenders.
Can I customize the length of the shock cord for specific projects?
Yes, shock cord is available by the foot or in bulk rolls, allowing you to cut exact lengths for your needs. To create professional-grade custom ties, you can use specialized hardware such as hog rings, crimps, and shock cord hooks to secure the ends without relying on bulky knots.
What are the primary uses for shock cord on a boat?
Common marine applications include securing boat covers and tarps, bundling sails or canvas when not in use, and attaching boat fenders. Because of its elasticity, it is also effective for managing running rigging, creating gear organizers, and providing shock absorption for lightweight loads.
How does marine shock cord handle UV and saltwater exposure?
Specifically labeled "marine-grade" cords are engineered to resist the "crunchy" texture and loss of elasticity caused by environmental stress. The synthetic jackets (like polyester) shield the internal rubber strands from sun damage and prevent rot, ensuring the cord continues to retract and extend fully even after prolonged exposure to harsh coastal elements.
Is Dyneema-covered shock cord worth it?
Dyneema-covered shock cord offers increased abrasion resistance, reduced friction, and longer service life compared to standard polyester sheaths.
