C. Sherman Johnson Splice Line Gate Kit - Midship f/One Side

The C. Sherman Johnson Splice Line Gate Kit – Midship for One Side (SKU CW80954) is a purpose-built marine fitting that enables secure integration of modern Dyneema and Spectra synthetic line with standard stainless steel lifeline systems. This splice line gate kit allows sailors and cruising boaters to transition from traditional wire cable to lightweight synthetic alternatives without replacing entire lifeline assemblies, making it an efficient upgrade path for vessels ranging from weekend cruisers to offshore racing boats.

Designed specifically for midship installation on one side of the vessel, this fitting addresses a key technical challenge: Dyneema and Spectra lines require different connection methods than conventional wire due to their reduced stretch and fiber composition. The splice line gate system accommodates these load characteristics while maintaining the structural integrity of your lifeline system. Weighing just 1.85 lbs with compact dimensions of 7 x 1 x 9 inches, the kit integrates seamlessly into existing rigging without adding bulk or weight aloft. Both US Sailing and ISAF now permit Dyneema/Spectra lifelines for offshore racing, and this fitting provides the connection hardware needed to meet those standards while preserving compatibility with conventional fittings.

This kit is ideal for cruising sailors seeking to reduce weight and improve longevity compared to stainless steel cables, which are subject to corrosion in salt air and require periodic inspection for wire breakage. Offshore racers benefit from the weight savings and the ability to meet current class specifications. The midship, one-side configuration makes it suitable for staged replacement—install one side first, evaluate performance, and add the opposite side later if desired. Installation requires basic splicing knowledge or professional rigging support, making it accessible to boats with either DIY maintenance programs or relationships with local marine riggers.
