Top 4 Best Crab Lines for Pots, Traps & Trot Lines

1. KUFA Sports Non-Lead Sinking Line – Best for Sinking Line

Features:
  • Length: 100 feet.
  • Diameter: 5/16″
  • Color: White/Blue
  • 2000lb break strength.
  • Resistance to abrasion and UV light.

Strong but lightweight, KUFA Sports’ non-lead sinking line is an excellent premium choice if you’re looking for a high quality crabbing line that won’t break under duress. Boasting a 2000 pound break strength and a strong resistance to both abrasion and UV light, this line is perfect for crab, lobster and prawn traps.

While it is a bit more expensive than the Promar Polyethylene line, it’s definitely a superior product. It’s almost deceptively strong given how lightweight it is and thanks to it’s sinking properties you don’t have to worry about it being caught or cut by your boat’s propeller.

We strongly recommend this crabbing line if you’re looking for the best crab line on the market. Compared to the cost of high-end recreational and commercial crab traps, spending a little extra on the rope is worth it considering a faulty line can cost you the whole trap.

Pros
  • Non-leaded and sinking.
  • A bit wider at 5/16″ than the other quarter-inch lines on this list.
  • Extremely durable and resistant to UV damage.
  • Don’t have to worry about the line getting caught in the propeller of your boat.

Cons
  • A bit more expensive than the other crab lines we’ve reviewed.

2. KUFA Sports Crabbing Accessory Kit – Best for All-in-One Accessory Kit

Features:
  • Length: 100 feet.
  • Diameter: 1/4″
  • Non-lead sinking line.
  • Includes a clipper, harness, bait bag, measuring gauge and float.

If you’re looking for an all-in-one crabbing kit that comes with everything you need to safely attach your crab trap then this is the option for you. The crabbing line itself is 100 feet long and measures at 1/4″ diameter and is non-lead and sinking. It also includes practically everything you need to start crabbing, including:

  • A bait bag that you can clip onto your trap or pot.
  • A four-arm crab trap harness so you can be sure to pull up your trap quickly and safely without losing crabs.
  • A crab measuring gauge that helps ensure you only keep crabs that are the legal size.
  • A red/white crab float so you don’t lose track of where you placed your trap.

Purchasing each of these separately would cost significantly more than this all-in-one kit offers, so if you know you’ll be needing all of these products you may as well order them together. The harness, line and float itself would cost more to order separately than the entire cost of this package.

The only real drawback is sometimes they ship a floating line instead of a sinking line. This seems to be a fairly rare occurrence that hopefully the manufacturer or distributor has worked out, but it’s worth considering before placing an order.

Pros
  • The 100 feet line is non-lead and sinking.
  • Includes everything you need to safely attach your crab trap.
  • Very cost effective to purchase in a bundle.

Cons
  • Sometimes the package will include a polyethylene floating line rather than a sinking one, but this seems to be a rare occurrence.

3. Promar Polyethylene Crab Line – Best for Floating Line

Features:
  • Length: 100 feet.
  • Diameter: 1/4″
  • Color: Yellow/Green
  • Made of very strong polyethylene.
  • Will easily last for years.

Promar’s crab line is made of an ultra strong and durable polyethylene material that measures at 1/4″ in diameter and comes in 100 feet lengths. It’s both easy to splice with scissors and boasts an extremely high visibility that ensures you won’t lose sight even in bad weather or heavy chop.

Keep in mind that this polyethylene line floats, so it will need to be attached to a pot, trap or something weighted to ensure it sinks to the bottom. If you’re specifically interested in a weighted non-float line there are some others on this list that will be better suited for your needs but for regular crab traps this works great.

The only real downside is that it can be pretty difficult to tie down. The rope is rigid which may make it more durable, but it also makes it difficult to bend. Once you’re able to tie the line the knot maintains it’s strength without compromising the integrity or strength of the rope.

Pros
  • The polyethylene material floats.
  • High visibility yellow color with green streaks.
  • The 1/4″ diameter is great for recreational traps and pots.
  • Can easily be spliced and cut with scissors.
  • Inexpensive.

Cons
  • It’s a bit rigid which makes it difficult to tie into knots.

4. Sea Striker Crab Trap Line – Best for Crabbing from a Shallow Pier

Features:
  • Length: 48 feet.
  • Color: White
  • Good for smaller recreational crab traps.
  • Shorter line for crabbing from shallow water or a pier.
  • Twisted line.

At only 48 feet, Sea Striker’s crab trap line is much shorter than most of the other options on this list but is also less expensive. If you plan on using a simple two ring crab trap from a pier or in shallow water then this line will work great, but for deeper water you’ll definitely want to go with one of the other options on this list.

Pros
  • Cheapest crab line we’ve reviewed.
  • Works okay for smaller traps that are used in shallow water.

Cons
  • Not recommended for deeper water or larger traps.
  • The rope is unlikely to last for more than half a dozen crabbing trips.

Types of Crabbing Line

Nylon

Nylon has been a popular choice since it does not mildew or deteriorate when it is stored wet. It also stretches under load and is very strong. Other lines will fall apart with continued use. The standard length is between 50-100 feet long or it can be cut to suit your needs.

Polyethylene

Polyethylene is another popular choice since it’s quite cheap, durable and can easily be spliced and cut to fit your needs. Most standard polyethylene lines are sold in 100 feet increments but can easily be cut depending on your needs. Keep in mind that polyethylene lines will float so you’ll need to make sure it’s sufficiently weight in order to get it to sink.

Floating vs Sinking Crab Line

You’ll also need to carefully consider whether you want floating or a sinking crab line. We recommend you go with a non-leaded sinking crab line so you don’t have to worry about it getting caught in your boat’s propeller.

If you plan on using your crabbing line with a trap you can make due with a polytheylene line since it will sink due to the weight of the pot. Just be careful not to get it caught in your boat’s prop or you could end up damaging your boat.

Cutting & Splicing Crabbing Line

When cutting line make sure you cut it to suit the depth of the water in which you wish to crab. If, for example, you crab in eight (8) feet of water, cut about twelve feet of line. You will need extra for the following reasons: You have to tie one end onto your trap and the other to your float. Another reason for extra line is because passing boats will create a wake and if your line is too short, your trap will be pulled off the bottom as the water rises and it will be moved somewhere else.

Once you cut your line it might start to unravel (pictured above). To prevent the line from unraveling, you should seal the ends of the line to make sure this does not happen. To do this you will need a source of heat such as a propane torch, matches, a soldering iron, etc.

Place the end of the line in the heat source. A hot knife blade works well. USE CAUTION Nylon will melt in high heat. The end of the line seals because the nylon melts and forms a melted blob on the end. The melted nylon may drip. DO NOT get this on your skin as you will get a nasty burn. Let the line cool before you pick it up. Repeat the process for each piece of line you intend to use. As you crab, Check the knots to make sure they are not coming lose. Even a good bowline (one of the most versatile knots you can use) will loosen with time.
