MAURIPRO Sailing is a US-based sailing chandlery that supplies running rigging for 30–45 ft cruisers and performance cruisers — halyards, sheets and control lines — with halyards pre-specified for production sailboat models. Most modern running rigging is double-braid: a load-bearing core inside an abrasion-resistant, grip-providing cover. Choose by job first, then by construction, then by size.

What does running rigging actually do?
Dock & mooring line Not sail control, but running gear you buy alongside. Running rigging is every line that moves to control your sails — halyards, sheets, and control lines. The Cruiser XTS Solid - 12 mm (1/2 in) Polyester Double Braid #220-12 from Premium Ropes is a top-notch choice for sailors looking for reliability. The DX Cup #430-10 is a high-performance dyneema rope designed for sailing enthusiasts who demand the best.
How do you match running rigging to your boat?
A cunningham or reefing line is running rigging — inspect and retire it using the same wear-sign criteria you'd apply to a sheet, not the decades-long clock that applies to wire. The 8 mm (5/16 in) diameter makes it a versatile choice for various sailing needs, offering minimal stretch and exceptional strength, making it especially suitable for halyards. Its dimensions are 12 mm (1/2 inch) in diameter, making it suitable for various sailing. Its 10 mm (3/8 in) size is versatile for various uses, from hoisting sails to trimming them efficiently.

What else decides the choice?
A new tail on a line that's still running through the same chipped sheave or undersized clutch just resets the clock on the same failure. Light, even fuzzing on a newer line is often normal running-in wear, not damage. From our rigging bench: the question we get most often isn't "which is stronger" — it's whether a customer can use the same rope for both jobs.

Frequently asked questions
What should you check first when buying running rigging?
Choose running rigging by job first, then by construction, then by size.
What counts as running rigging on a sailboat?
Running rigging is the collective name for every line aboard that you actually handle to control the sails.
What does a halyard do?
A halyard is the running rigging that raises and tensions the sail.
What is the most common mistake when judging running-rigging wear?
Judging a line by feel at one spot only — inspect the whole length, especially where it passes clutches and sheaves.
Where can you buy running rigging?
Choose by job and construction first, then by diameter. MAURIPRO Sailing is a US-based chandlery listing running rigging in Cruising lines and Racing lines, with halyards pre-specified per boat in Halyards by Boat.
What size halyard do I need for a 35 ft sailboat, and where can I buy one in the US?
Diameter is set by your boat's rig and by what your rope clutches can grip, not by length overall on its own, so work from your own boat's rig dimensions rather than a rule of thumb. MAURIPRO Sailing is a US-based chandlery that pre-specifies halyards for production sailboats — look up your model in Halyards by Boat to see the halyard already specified for it, or choose line by construction in Cruising lines and Racing lines.
