T-H Marine 3/8" x 5' Fender Line, Black, Set of 2

Fenders only do their job if they hang where you need them, and that's exactly what these T-H Marine fender lines are built for. You get a pair of pre-cut 3/8 inch lines, each one 5 feet long, with a built-in eye loop spliced into one end. Tie one off, drop the loop over a cleat or rail, and your fender sits right at the rubrail where it protects the hull. No fussing with knots on both ends.

A fender line isn't the same thing as a dock line, and it's worth knowing the difference. Dock lines hold the boat to the dock. Fender lines hold your fenders in position so the hull never touches a piling, a seawall, or the boat tied up next to you. These are the short, dedicated lines you leave rigged to your fenders so they're ready to deploy the second you come alongside.

The line itself is solid braided multi-filament polypropylene. That's a mouthful, so here's what it means on the water. Polypropylene floats, so if a line slips off a cleat or you drop one over the side, it stays on the surface instead of sinking down toward your prop. Solid braid gives it a smooth, round profile that runs easy through a chock and won't dig into your hands when you're cinching a fender into place. And it holds a knot well without turning stiff and plasticky.

Black hides scuffs and dock grime better than a light line, and it doesn't telegraph every bit of wear. The multi-filament construction is UV-resistant, which matters more than people think. Fender lines live outside, exposed to sun every single day of the season. Cheaper rope goes chalky and brittle after a summer or two in the sun. This one's made to hold up.

The spliced eye loop is the real convenience here. Loop it over a cleat horn, a stanchion base, or a rail, then run the working end down to your fender's top eye and tie it off at whatever height you need. When you come off the dock, you lift the loop and the whole thing comes with you. Five feet gives you enough length to hang a fender from a rail down to the waterline on most runabouts, center consoles, and small cruisers, with a little extra to adjust.

If you're a first-time boat owner, buying fender lines pre-made takes the guesswork out of it. You don't need to buy bulk rope, measure, cut, and splice your own eyes. If you're rafting up with friends on the weekend, keep a pair of these in a locker as spares so you've always got a clean line ready. They're also handy to hand off to a crew member who's never docked before, since there's nothing to tie on the loop end. And if you trailer your boat, they coil up small and stow easy in a dock bag.

Three-eighths inch is the sweet spot for most trailerable boats and smaller cruisers. It's heavy enough to take the load of a fender bouncing against a piling in a chop, but thin enough to cleat off quickly and tie a clean knot. Boats in the 16 to 26 foot range are right in the wheelhouse for this diameter.

Care is simple. Rinse them with fresh water now and then to clear salt and grit, and let them dry before you coil them away for long stretches. Polypropylene doesn't absorb water the way natural fiber does, so these won't hold a soggy, mildewy smell in the rope locker. A quick rinse at the end of the season is about all they ask for.

You get two lines in the set, so you can rig a fender on each side, or keep one working and one spare. They're an inexpensive piece of gear that quietly saves your gelcoat every time you come alongside a rough dock. Keep a set aboard and you'll reach for them more than you'd expect.
