Sailing Ropes, Marine Knives & Multi-tools

Yes, on decathlon.com.gr you will find an excellent variety of sailing ropes and specialized nautical knives or pocket knives. Our collection includes ropes of various diameters for every use on the boat, as well as ergonomic stainless steel knives with integrated marine tools, essential for safety and daily tasks on deck.

The choice of rope is based on its intended use, as each type of rope has different elasticity and strength properties:
For Halyards (ropes used to hoist sails): You need ropes with near-zero stretch (such as ropes with a Dyneema core or reinforced polyester), so that the sails remain firmly tensioned without sagging under wind pressure.
For Sheets (ropes used to trim sails): Here you need ropes with a good grip in the hand, soft and flexible, that run smoothly through winches and blocks.
For Mooring lines (ropes used for docking/anchoring): In this case, you want high elasticity (polyamide/nylon ropes) so they can absorb shocks from waves and prevent stress on the boat's cleats.

The difference lies mainly in design and portability. A sailing pocket knife (folding) is multi-functional, folds away safely, and fits in your pocket. It usually includes additional nautical tools, such as a shackle key and a marlinspike for untying knots.
A nautical knife (fixed blade) is sturdier, typically kept in a sheath on a belt or in an accessible spot on the boat, and is designed for immediate cutting in an emergency (e.g., if a rope gets tangled around someone's leg). It often features a serrated blade that cuts through thick ropes much faster than a straight edge.

There is no specific timeframe, as wear depends on usage and exposure to the elements. However, you must replace a rope immediately if you notice tears or severe fraying on its outer cover, or if the rope has become excessively stiff and "dry" from salt and sun exposure, losing its flexibility. Also, replace it if you notice localized thinning in diameter, which indicates that the internal core has suffered damage.
Extra Tip: With proper maintenance and washing, ropes on pleasure craft can last safely for 3 to 5 years.

Yes, at Decathlon we place a heavy emphasis on safety. For beginners and children, we recommend sailing pocket knives featuring a rounded tip (safety/blunt tip) to prevent accidental puncture injuries on a moving boat. Furthermore, all our models come with a blade locking system (liner lock or back lock) that secures the blade when open, preventing it from accidentally closing on your fingers while cutting a rope.

The technical specifications that ensure the longevity of a rope at sea are:
High Tenacity Polyester Material: It offers excellent resistance to UV rays and does not lose its strength when wet, unlike other materials.
UV Stabilization: Special treatment of the fibers during braiding to prevent them from "burning" and fading under the hot summer sun.
Double Braid Construction: An independent inner core that bears the entire load and a durable outer jacket that protects the core from friction on winches and stoppers.
