Boat Ropes & Dock Lines at Defender

Not all ropes are created equal and something you tie your dog to the bike rack outside a coffeehouse with is not suitable for your boat.
While serious boating enthusiasts know that ropes are called lines, even recreational boaters understand the importance of having quality ropes, lines and rigging in place for their boat.
The last thing any captain wants to be is stuck on the water without the right tools and being short on dock lines and rigging supplies is at the top of that list.

At Defender we know how the art of sailing has continued into the present day, and though sailing uses the same principles as ancient schooners and clippers, the technology has evolved over the decades providing the cutting edge of windpower technology to assist you on your voyage.
From anchor and dock lines to competition sailing lines, selecting the right rigging and lines for your sailboat is as challenging as mastering the elements and riding high on the sea, but Defender offers everything you need to hoist your sail and tack into the wind for your next adventure.
Learning how to navigate the ins and outs of rigging is half the battle.
With so many manufacturers and types of rigging to choose from, we have constructed this cheat sheet to help you decide.

Modern Rigging Supplies at Defender

Polyester and synthetic kernmantle construction has replaced hemp and organic rope with staggering results when it comes to lighter relative weight, increased durability, water resistance, and a better "hand" or feel when needed for extensive handling.
Thicker ropes typically carry more load but sacrifice flexibility and ease of hand.
Lines are made of blended materials, and advanced synthetics for incredible strength, flexibility, and elimination of kinks.

Here are the most common rigging materials:
  • Dyneema: High strength, low stretch, this line floats, yet is very expensive.
  • Nylon: An early synthetic, nylon is not used very often for rigging anymore, but due to its ability to handle shocks, it works great for anchors and mooring. It loses much of its strength when wet and does not tolerate UV very well.
  • Polyester: Strong, flexible, and easy to handle. Used for racing and competition, however it does not float due to its density.
  • Polypropylene: Strong, relatively inexpensive compared to Dyneema, this line floats, but does not resist UV damage very well.

  • Line selection

  • Single braid: Resists kinking, with two types: either a stiffer static line for performance and heavy loads, or a softer hand that is easier to handle for sheet and hand-adjusted lines.
  • Double braid: A braided core on the inside with a braided outer sheath, this type of line closely resembles climbing rope. Good for strength and constant handling, but also reduces friction and damage to other equipment it may come into contact with.
  • Three strand: What looks the most like traditional rope, this line is good for anchors, mooring, and other loads which might require stretching under heavy loads.
