Common Concerns Answered
Is professional splicing required for this kit?
Professional splicing is strongly recommended for this kit to ensure critical safety standards are met. While the kit provides the necessary fittings, the integrity of the high-tech line splice is paramount for lifeline security, and improper DIY splicing can compromise system strength and lead to premature failure.
What if the included 6' of Dyneema is not enough?
The 6' of Dyneema included is for a single run; for longer lifeline sections or double lifelines, additional Dyneema line will need to be purchased separately. It is essential to accurately measure your required lengths before ordering to avoid supplementary purchases.
What are the primary advantages of using Dyneema/Spectra lifelines over stainless steel?
Dyneema/Spectra lifelines offer a significant weight reduction, increased strength-to-weight ratio, and are less abrasive to the synthetic material itself compared to stainless steel cable. This translates to improved vessel performance and reduced maintenance, especially in demanding offshore conditions.
Frequently Asked Questions
What is the C. Sherman Johnson Splice Line Gate Kit used for?
This kit is used to create a functional gate within Dyneema or Spectra lifelines, allowing for convenient access to and from the vessel while maintaining the high strength and low stretch properties of modern synthetic rigging.
What type of line is compatible with this kit?
This kit is specifically designed for use with high-strength Dyneema and Spectra lines, which are modern synthetic fibers known for their exceptional tensile strength and low extensibility.
What is included in the C. Sherman Johnson Splice Line Gate Kit?
The kit includes specific C. Sherman Johnson fittings: LS-3100 Over Center Gate Hook w/ Splice Eye, LS-3200 Splice Eye to Splice Eye Fitting, LS-3300 Gate Eye to Splice Eye Fitting, LS-3400 Adjuster w/ Splice Eye, and 6' of Dyneema line.
Can this kit be used for double lifelines?
Yes, the components can be utilized for double lifelines, but you will need to purchase additional Dyneema line to accommodate the second run and ensure sufficient length for both sides.
What are the benefits of using Dyneema/Spectra lifelines?
The benefits include significantly reduced weight compared to stainless steel, superior strength, minimal stretch, increased safety due to higher breaking strength, and reduced chafe on the lifeline material itself, leading to a longer lifespan.
