Nylon stretches under load, so it soaks up the shock of wakes and wind instead of jerking your cleats. It comes with a 12-inch pre-spliced eye, so you just drop the loop over a piling and go.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe T-H Marine dock line is a 3\/8-inch by 15-foot rope built for one job and built to do it for years: holding your boat at the dock. It's twisted three-strand premium nylon, white, with a 12-inch pre-spliced eye already worked into one end. Drop that loop over a piling or a dock cleat, run the tail to your boat, and you're tied up.\u003c\/p\u003e\n\u003cp\u003eNylon is the reason this line works. Three-strand twisted nylon stretches under load, and that stretch is what you want in a dock line. When a wake rolls through or the wind gusts and shoves your hull, the line gives a little instead of snapping tight. That elasticity soaks up the shock so it isn't transferred straight into your cleats, your bow eye, or the dock hardware. A stiff line hammers everything it's tied to. A nylon line breathes with the boat.\u003c\/p\u003e\n\u003cp\u003eThe numbers back it up. This line carries a 3,240-pound breaking strength and a 648-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 plan around, and it builds in a big safety margin for shock loading, chafe, age, and knots. For a dock line, you always size to the working load, not the breaking point. 648 pounds of continuous holding power covers a lot of boat under normal conditions.\u003c\/p\u003e\n\u003cp\u003eSpeaking of sizing: 3\/8-inch is the go-to diameter for boats up through the mid-20-foot range. Runabouts, bay boats, center consoles, smaller cruisers, they're all comfortable on 3\/8-inch line for routine dockage. If you're on a heavier boat, or you sit in a spot that takes a beating from current or storm surge, step up to a larger diameter. And remember this is a single 15-foot line. A proper tie-up uses several, a bow line, a stern line, and a pair of spring lines to stop the boat from surging forward and back in the slip. Most boaters keep four or more aboard and buy them to match.\u003c\/p\u003e\n\u003cp\u003eThe 15-foot length is a sweet spot for most slips and floating docks. It gives you enough tail to reach the cleat, adjust for tide, and still coil down without a pile of excess rope underfoot. The pre-spliced eye saves you the trouble of tying a bowline every time you come in. Loop it over the piling, cleat the working end, done. When you leave, lift the eye off and go.\u003c\/p\u003e\n\u003cp\u003eOut in the weather, this line holds up. The nylon is UV, sunlight, abrasion, and saltwater resistant, so it lives on the dock full time without going brittle or chalky the way cheap rope does. That said, do your line a favor and add chafe protection anywhere it rubs, a section of hose or a proper chafe guard where the rope crosses a rough piling or a chock edge. Abrasion is what kills dock lines, not load. Rinse the salt off now and then and it'll last for seasons.\u003c\/p\u003e\n\u003cp\u003eOne more handling note. Three-strand line coils and cleats easy, and if you ever need to add your own eye or shorten a line, three-strand is the simplest lay to splice by hand. No special tools, just a fid and a few minutes. That's part of why it's stayed the standard dock line for decades.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Any boater who needs dependable, no-drama dockage on a small to midsize boat. First-timer setting up a new slip, or a seasoned owner replacing a tired, sun-baked line that's gone stiff. Who's it not for? Big heavy cruisers and yachts that need heavier line, and anyone looking for a dedicated anchor rode. This is a dock and mooring line, plain and simple, and it's a solid one.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eTwisted three-strand premium nylon construction stretches under load to absorb wake and wind shock so it doesn't hammer your cleats and hardware\u003c\/li\u003e\n  \u003cli\u003e3,240-pound breaking strength with a 648-pound safe working load gives a wide safety margin for most runabouts, bay boats, and center consoles\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch diameter is the go-to size for boats up through the mid-20-foot range for everyday dockage\u003c\/li\u003e\n  \u003cli\u003e15-foot length reaches most slip and floating-dock cleats with enough tail to adjust for tide\u003c\/li\u003e\n  \u003cli\u003e12-inch pre-spliced eye drops right over a piling or cleat, no knot tying required\u003c\/li\u003e\n  \u003cli\u003eUV, sunlight, abrasion, and saltwater resistant so it holds up to full-time outdoor exposure\u003c\/li\u003e\n  \u003cli\u003eWhite finish keeps a clean look at the dock and blends with most boats\u003c\/li\u003e\n  \u003cli\u003eThree-strand lay is the easiest to hand-splice if you ever need to add an eye or shorten a line\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\u003eHow much weight can this dock line hold?\u003c\/summary\u003e\n    \u003cp\u003eIt has a 3,240-pound breaking strength and a 648-pound safe working load.
