Key gains – ~1 min read
- ✓ Lower stretch and superior UV resistance to nylon, extending line life.
- ✓ Custom lengths and colour‑matched branding cut stock waste.
- ✓ ISO 9001 quality management ensures consistency and traceability.
Many sailors still reach for off‑the‑shelf nylon because it’s inexpensive, yet they accept higher stretch and faster UV degradation. What if you could move to a tailor‑made 8‑12 mm polyester line that holds its shape, trims faster, and lasts longer without blowing the budget? In the sections below, we outline the design choices and ordering tips that turn that ‘what if’ into a measurable on‑water upgrade.
Understanding double braid polyester yacht rope
After seeing how iRopes tailors rope solutions for specific vessels, it’s useful to know exactly what makes a double braid polyester yacht rope stand out. Double‑braid polyester yacht rope is built with a braided polyester core surrounded by a braided outer cover of the same fibres, delivering low stretch, high tensile strength, and excellent UV and chemical resistance. This construction explains why the product frequently appears when searching for yacht braid rope for sale.
Understanding the key benefits helps you decide whether this rope meets your rigging needs. Below are the three advantages that most sailors notice first:
- Low stretch – the rope holds its length under load, keeping sail trim accurate.
- High tensile strength – a 12 mm double braid polyester rope can withstand roughly 37 kN (8 400 lb) before breaking.
- UV & chemical resistance – exposure to sunlight and saltwater degrades it far slower than nylon.
When a sailor asks, “What is double‑braid polyester rope?” the answer is simply the definition above: a core‑cover system that combines strength with durability, making it a favourite for halyards, sheets, and mooring lines.
“The consistency of iRopes’ polyester rope made our offshore rally smoother; the low‑stretch feel gave us confidence in every tack.” – offshore skipper, customer feedback.
With a clear picture of the rope’s construction and its practical benefits, you can now evaluate size options and load ratings in the next section, where we break down the specifics of a 12 mm double braid polyester rope.
Choosing the right size and load – 12mm double braid polyester rope guide
Now that you understand how a double‑braid polyester yacht rope is built, let’s focus on the numbers that matter when you size a line for your vessel. The 12 mm version is a favourite for halyards and sheets because it balances strength with manageable weight.
Below is a compact spec sheet that captures the most relevant data for a 12 mm line. Use it as a reference when comparing alternatives or quoting a supplier.
Technical Specs (12 mm)
Key performance figures for a 12 mm double‑braid polyester rope.
| Diameter | Breaking Load | Weight (kg/100 m) | Stretch | Price (USD/m) |
|---|---|---|---|---|
| 12 mm | ≈ 37 kN | 12.8 | ≈ 3–4 % | $1.60–$16.00 (retail ref.) |
When you match a rope to a boat, consider both the vessel’s size and the intended load. The following three‑step checklist helps you pick the right diameter without over‑engineering.
- Identify the maximum load your sail plan will impose (e.g., mainsail halyard, jib sheet).
- Apply a safety factor of 5 : 1 to convert breaking load into a working load limit.
- Select the smallest diameter that still exceeds the calculated working load; for a 30‑ft (≈ 9 m) cruiser, 10–12 mm is usually optimal.
Answering a common query: a 12 mm double‑braid has a typical minimum breaking load of ≈ 37 kN (8 400 lb). Using a 5:1 safety factor gives a working load limit around 7.4 kN (≈ 760 kg or 1 680 lb).
Armed with the numbers, you’re ready to explore purchasing options, bulk pricing, and the customisation possibilities that iRopes offers for every length, colour, and branding need.
