Advantages and Uses of Roller Bearing Sailboat Blocks | Expert Advice

So you may be asking yourself, Why would I need a fancy shmancy Roller Bearing Block? What makes them so special anyway? Well..we are here to show you. One of the greatest advantages of a Roller Bearing Block over a Plain or Ball Bearing Block is the low friction safe working loads.  Highly loaded lines in a Roller Bearing Block will run faster, and adjustments are much easier. Roller Bearings may not necessarily run as free as ball bearings, but they do offer a significantly higher working load. Ball […]

Advantages and Uses of a Ball Bearing Sailboat Block | Expert Advice

Today we are highlighting ball bearing blocks as part one of our three part discussion on blocks, their characteristics, and uses. So, what is a Ball Bearing Block?  In its simplest form, a ball bearing block it is a housing containing a rolling sheave with balls lining the race on the either side of the sheave.  The balls reduce friction by minimizing bearing surface and roll between the moving surface and the non-moving part of the block. Because of this, lines are able to slide […]

Sailboat Line Materials: What is Nylon Line? | Expert Advice

Nylon line is a commonly used thermoplastic found in many everyday items. It has long been used in the modern marine industry for dock lines and anchor rodes (a fancy anchoring term for ‘line’). When used alone (not blended with another line material), Nylon line serves as a well functioning dock line material. Nylon is naturally semi-elastic, abrasion resistant, and fairly flexible. These traits make it easy to hold onto and tie off your boat. For dock lines, Nylon will give you peace-of-mind […]

Sailboat Line Materials: What is Polypropylene Line? | Expert Advice

Polypropylene Line is a thermoplastic polymer material that has a wide variety of uses.  It is commonly found in many household, textile, and industrial applications. For the marine industry, polypropylene line is tough, flexible, and strong yet lightweight enough to float which makes this ideal for dinghies and small keel boats. Polypropylene Rope Characteristics: Light weight: when compared to  similarly-sized diameter lines. Does not absorb water Floats Excellent shock absorption Easy to splice Economical Low tolerance to UV Low Melting Point Low Abrasion Resistant Some common applications […]

Sailboat Line Materials: What is Vectran Line? | Expert Advice

When you need the Hercules of lines, look no further than a Vectran rope. Vectran is a type of liquid crystal polymer (LCP). It is similar to Dyneema with a few key differences. Vectran rope made its way into the sailing industry due to its very desirable properties of low stretch, or elongation under load. It is comparable to Dyneema but much less creep, and elongation over time. Vectran also offers higher resistance to heat. The trade off comes in that […]

Sailboat Line Construction: Single Braid vs Double Braid | Expert Advice

There are several factors that affect marine rope performance. The main two are the construction and material. Today we’re going to talk about construction differences in marine rope. The major construction difference comes in the form of a double braid line and a single braid line. Although, it is hard to just talk about construction without discussing material differences so we’ll get to the a little later. A single braid, at its most basic, is a braided line that has no cover and no core. […]

Sailboat Line Materials: What is Dyneema line? | Expert Advice

Sailing Line is made with a wide variety of materials, each have unique characteristics that allow them to excel in different applications. In our next few blog post we are going to take you through each option and describe what makes it unique, and how you can use it. Next up is Dyneema line. Dyneema line is made of a popular and versatile “high tech” material that is used in many line applications today.  It is used in single braid and double braid applications. Here’s […]

Sailboat Line Materials: What is Polyester Line? | Expert Advice

Marine rope is made with a wide variety of materials, each have unique characteristics that allow them to excel in different applications.  We’re going to take you through each, and describe what makes it unique and how you can use it.  First up is Polyester, the MacGyver of line materials. Polyester marine rope is the most ubiquitous line material found on sailboats from dinghies to large keel boats and beyond.  It’s uses range from halyards to sheets to control lines to covers for polyester cores […]
