Bimini Twist Versus the Spider Hitch
Deciding on a knot for your double-line
No Trouble Double Line
Oftentimes an angler is stuck with the decision of whether or not to create a double line or loop coming off of the main line on their reel. There are various reasons why someone may need to create a loop in their line—loop to loop connection such as attaching fly line to backing, connecting a wind-on leader or the need to create a strong connection to a barrel or snap swivel. There are a few different ways to create a loop or double line, but the most common knots used are the spider hitch and the bimini twist.
Spider Hitch or Bimini Twist?
Both of these knots will create a double line or loop but when tied properly, only the bimini twist will provide a knot with 90%-95% of the original line strength. A spider hitch can be faster and easier to tie, especially while in a rocking boat, but if the knot isn’t tied properly and the “hitches” don’t come tight in the proper order, the knot has a very good chance of failing. Because of the nature of the knot, when using a braided line, a spider hitch will frequently fail due to the fish putting enough tension on the line to have the wraps of a spider hitch cut through and break the knot. A bimini twist has proven to be much more effective when using a small diameter line such as a braided line.
Why the double line?
There are a variety of different reasons for the need to create a loop or double line in terminal tackle applications. One of the most popular applications of double line is to create a stronger knot connection to a swivel or other terminal connection. Besides knot strength, another benefit to having double line is protection against the line chafing. If the bill or tail of a fish is able to chafe the double line enough to break through one strand, there will still be another strand of line to successfully land the fish. A bimini twist will also create a loop that is the starting point for attaching a wind-on leader.
Tips for a solid knot:
To ensure your bimini twist retains as much of the original line strength as possible, you have to make at least 30-40 twists in the line after creating your loop. There are countless ways to finish the knot (knotless, half-hitches, etc.), but the best advice would be to find the finish that works best for you and stick with it. A short bimini twist (up to five feet) can easily be tied by one person but tying a bimini longer than five feet normally takes two people. The length is up to the angler, but keep in mind that double line is limited to 15 feet (4.57 meters) for all line classes up to and including 20 lb (10 kg); and is limited to 30 feet (9.14 meters) for line classes over 20 lb (10 kg). For freshwater species, the double line on all classes of tackle shall not exceed six feet (1.82 meters).
