Introduction
The document introduces the RC 30 and RC 40 carbon furling systems developed by Reckmann Yacht Equipment GmbH. These systems are designed for sailors who previously used a Tuff Luff racing forestay system alongside a standard roller reefing system.

Specifications
The RC 30 and RC 40 systems are suitable for yachts ranging from approximately 42 to 68 feet with forestay lengths up to about 30 meters. The carbon profiles are lightweight, with the RC30 S2 profile weighing 0.327 kg/m and the RC40 S4 profile weighing 0.77 kg/m. This makes the system lighter than traditional racing profile forestay systems.

Design and Functionality
The systems are designed to eliminate the need for retrofitting before each race. The carbon drum can be easily removed manually to tack the sail on deck. The lightweight design allows for easier mast trimming and requires reduced backstay tension, contributing to a weight saving of approximately 25 kg over conventional systems, which reduces the pitching moment.
