What this video covers
Schaefer Marine manufactures a boom furling system designed to simplify mainsail reefing and storage.3:45 The system utilizes a mandrel to roll the sail, incorporating a luff tape design that isolates batten compression to prevent the sail from bearing against the mast.1:56 This configuration allows for reefing on any point of sail by easing the mainsheet.2:34 The end fittings are CNC-machined from 90-pound blocks of 6061-T6 aluminum, resulting in 12-pound components that feature double races of Torlon balls to minimize friction.2:55 Additionally, the company produces a line of M-blocks available in three sizes and eight configurations.3:42 These blocks are machined from 6061-T6 aluminum and utilize a combination of Torlon and Delrin bearings to handle high loads, with some models rated for a 5,000-pound safe working load.4:18 The blocks support lashing to pad eyes as an alternative to traditional shackles, which can improve line lead articulation and reduce weight.4:01
