T-H Marine 3/8 in. x 10 ft. Hollow Braid Utility Line

Every boat needs a few lengths of good utility line kicking around, and T-H Marine's 3/8 inch hollow braid is exactly the kind of rope you reach for without thinking twice. You get 10 feet of polypropylene braid in a high-visibility red and white pattern, rated at 816 pounds breaking strength with a 163 pound safe working load. It's light-duty line, and that's the whole point. Keep a couple of these in a locker and you'll find a job for them just about every time you head out.

Polypropylene is the workhorse material for general-purpose rope, and it earns that spot for a simple reason. It floats. Drop this line over the side and it stays right on the surface where you can see it and grab it, which is exactly what you want in a throw line or any rope you're handling around a running prop. It's also light and easy to coil, so it won't weigh down a bag of gear or fight you when you stow it. The usual knock on poly is that sunlight breaks it down over time. T-H Marine builds UV resistance into this one, so it holds up to season after season of sun and salt spray a lot better than bargain rope that goes brittle and chalky after a single summer.

The hollow braid construction is what makes this line so easy to live with. There's no stiff inner core fighting you, so the rope lies flat, coils clean, and takes a knot without a wrestling match. Hollow braid is also about the easiest rope there is to splice. You can bury the tail back through the braid and form a soft eye in a few minutes with nothing but a fid and a little patience. No core to deal with, no fancy whipping required if you tuck it in properly. For a quick fixed loop on a fender line or a permanent eye on a tie-down, that's a real convenience you'll appreciate.

So what do you actually do with 10 feet of 3/8 inch line? Plenty. It makes a natural fender line on a small boat, a tie-down for gear on the casting deck, a lashing for a cooler or a spare fuel can, a flag or burgee halyard, or just a general-purpose bit of rope for the hundred odd jobs that come up on the water. The red and white pattern isn't only for looks. High-visibility line is easier to spot floating in the water and easier to find fast in a crowded, tangled locker. And because poly floats, a length like this doubles as a handy throw line you can toss to someone who's gone over the side.

Be honest with yourself about the numbers, though. The 816 pound breaking strength is the load where the rope fails outright, not a figure to design around. The 163 pound safe working load is the number that matters day to day, and it reflects roughly a five to one safety factor, which is the sensible way to rate any rope. That makes this a light-duty utility line, not a primary anchor rode and not a dock line for a heavy boat. For holding a light tender, lashing down gear, rigging a flag, or keeping coiled in a locker for whatever comes up, it's perfect. For loads that actually matter to the safety of the boat or the people aboard, step up to heavier, purpose-rated line. We'd rather sell you the right rope than watch you trust a 3/8 inch poly line with a job it was never built to handle.

At this price there's no reason not to keep a few of these aboard. Stuff one in the ditch bag, one in the console, and one in the garage for trailer duty. It's the kind of gear you never think about until the moment you need it, and that's exactly when you'll be glad it's coiled and ready.
