Rated at 3,700 pounds breaking strength with a 740 pound safe working load, it's UV and abrasion resistant for daily tie-ups and permanent slip life.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThis is a T-H Marine double braid nylon dock line, 3\/8 inch thick and 25 feet long, finished in black with a pre-spliced 12 inch eye on one end. It's the line you reach for when you're tying up at a slip, a face dock, or a friend's pier, and it's built to take the daily grind of getting on and off the water without turning stiff or fuzzy after a season.\u003c\/p\u003e\n\u003cp\u003eDouble braid means there's a braided core running inside a braided cover. That construction gives you a rope that's strong, holds its shape, and stays smooth in your hands. No wiry strands to pick at your palms, no kinking when you coil it down. It runs cleanly through a chock and lies flat on the deck, which matters when you're single-handing and trying to get a line over a cleat before the wind pushes you off.\u003c\/p\u003e\n\u003cp\u003eThe reason we like nylon for dock duty comes down to stretch. Nylon gives a little under load, and that stretch works like a shock absorber between your boat and the dock. When a wake rolls through the marina or a storm surge starts working the hull, the line takes up the snatch load instead of transferring it straight into your cleats and deck hardware. A rope that doesn't stretch will shock-load everything it's tied to. This one breathes with the boat.\u003c\/p\u003e\n\u003cp\u003eOn the numbers, this line carries a 3,700 pound breaking strength and a 740 pound safe working load. Those two figures aren't the same thing, and it's worth knowing the difference. Breaking strength is where the rope actually fails. Safe working load is the everyday limit you should design around, and the big gap between the two is your safety margin for shock loads, aging, and abrasion. For tying up a boat you want to stay well under that working load, and 3\/8 inch nylon gives most trailer boats and smaller cruisers plenty of margin.\u003c\/p\u003e\n\u003cp\u003eThe 12 inch spliced eye is the part you'll appreciate every time you dock. Drop the loop over a piling or a dock cleat, run the bitter end back to your boat, and you're tied up in seconds. A factory splice is stronger and neater than an eye you'd tie yourself, and it won't work loose the way a knot can. It also makes the line easy to hand to someone on the dock who's catching your lines for you.\u003c\/p\u003e\n\u003cp\u003eBecause dock lines live outside, this one is built to resist UV and abrasion. Sunlight is what quietly kills rope over the years, breaking down the fibers until a line that looks fine snaps under load. The UV treatment slows that down, so a line left on a permanent slip holds up season after season. The abrasion resistance matters where the rope rubs, at the chock, over a dock edge, or around a rough piling. Those are the spots that wear first, and a tougher cover buys you time.\u003c\/p\u003e\n\u003cp\u003eMost boaters run more than one of these. A typical setup is a bow line, a stern line, and a pair of spring lines to keep the boat from surging forward and back in the slip. At 25 feet each, these give you room to reach cleats and pilings across a range of dock heights and tide swings. If you're setting up a new slip or refreshing a tired, sun-faded set, buy them in a batch so everything matches and you've got a spare in the locker. Black hides dirt and dock scuff better than lighter colors, and it won't show the grime that a white line picks up over a summer.\u003c\/p\u003e\n\u003cp\u003eGive them a fresh water rinse now and then to flush out salt and grit, coil them loosely so they don't take a set, and check the eye and the wear points at the start of each season. Treated right, a good set of nylon dock lines will outlast a lot of the other gear on your boat.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e3\/8 inch diameter and 25 foot length, sized for bow, stern, and spring lines on most trailer boats and small cruisers\u003c\/li\u003e\n  \u003cli\u003e3,700 pound breaking strength with a 740 pound safe working load for a wide safety margin\u003c\/li\u003e\n  \u003cli\u003eDouble braid nylon construction stays smooth in your hands and coils without kinking\u003c\/li\u003e\n  \u003cli\u003eNylon stretch absorbs wake and surge shock loads so they don't hammer your cleats and deck hardware\u003c\/li\u003e\n  \u003cli\u003e12 inch factory-spliced eye drops over a piling or cleat for fast, secure tie-ups\u003c\/li\u003e\n  \u003cli\u003eUV and abrasion resistant for season-after-season life on a permanent slip\u003c\/li\u003e\n  \u003cli\u003eBlack finish hides dock scuff and grime better than lighter lines\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized T-H Marine Supplies reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat's the difference between the 3,700 pound breaking strength and the 740 pound working load?\u003c\/summary\u003e\n    \u003cp\u003eBreaking strength is the point where the rope actually fails.
