Nautical Term: Rolling chocks
Definition of Rolling chocks
Rolling chocks refer to a type of chock designed for use in roller reefing systems. When a sail is being lowered, the roller reefing system uses the sail’s own wind pressure to roll it up around the forestay. As this process occurs, the sail must be guided along the forestay and through the roller reefing system. This is where the rolling chocks come in. These chocks are mounted on the forestay and are designed to provide a secure and stable holding point for the sail as it is being guided through the roller reefing system. In summary, rolling chocks are an essential component of roller reefing systems, serving to provide a secure and stable holding point for the sail as it is being guided through the roller reefing system. For example, when sailing in heavy winds, a sailor may choose to lower the mainsail using the roller reefing system. As the sail is being rolled up around the forestay, the sailor guides the sail through the roller reefing system, using the rolling chocks mounted on the forestay to provide a secure and stable holding point for the sail as it
