What Are Sailboat Blocks?

Sailboat blocks—also known as pulleys—are mechanical devices that redirect lines with minimal friction. They can feature single to multiple sheaves to optimize mechanical advantage and line control.

Top Block Types & Their Uses

• Single Blocks: Ideal for basic rigging like jib halyards and mainsheet adjustments.
• Double & Triple Blocks: Increase mechanical advantage—common in mainsheet systems and boom vangs.
• Ratchet Blocks: Include internal ratchet to hold load, perfect for sheets under heavy wind.
• Snatch Blocks: Hinged side plate to insert line under tension—great for quick rerouting.
• Fiddle, Cheek & Foot Blocks: Guide lines on deck and secure fixed line paths.
• Wire & Stand‑Up Blocks: Support wire rigging and load lead blocks.

Bearing Types Explained

• Plain (bushing): Durable and low‑maintenance—ideal for static loads.
• Ball Bearings: Provide smooth, low‑friction movement for dynamic lines.
• Roller Bearings: Heavy-duty, suitable for high-load halyards.

How to Select the Right Block

• Load Capacity: Always choose blocks rated above your peak load.
• Sheave Size: Match to rope diameter to prevent chafing.
• Mounting Style: Pick fixed, swivel, or soft‑loop based on line path.
• Material & Corrosion Resistance: Stainless steel, composite, or Dyneema‑reinforced bodies offer durability.

Why MAURIPRO Stand Out

MAURIPRO offers a wide selection of high‑quality sailing blocks designed to withstand heavy loads and reduce friction in every maneuver :contentReference[oaicite:0]{index=0}. We stock top brands like Harken, Lewmar, Ronstan, and Schaefer, engineered for both cruising and racing performance.

Choose from single, double, triple, ratchet, snatch, foot, cheek, wire, and linked blocks—each built with precision bearings and robust materials to deliver smooth handling, reliability, and long-term value.

Care & Maintenance Tips

Inspect blocks regularly for wear, corrosion, and bearing smoothness. Rinse with fresh water after saltwater use, and lubricate bearings as recommended to maintain optimal performance and longevity.
