Finmax Speed Hard Single Swivel Block with Becket (2 Sizes)

The Finmax Speed Hard single block with swivel and becket is engineered for high-performance handling of sheets and halyards on sailing vessels. This Finmax series is characterized by a lightweight design without ball bearings – instead, the blocks use low-friction bushings, making them exceptionally reliable under high loads and reducing maintenance needs. The cheeks are made from glass-fiber reinforced polyamide (nylon), providing impact resistance, UV stability, and durability in harsh marine conditions, all while keeping the blocks light in weight.

The swivel eye at the top allows the block to rotate freely, aligning naturally with the line of pull – especially useful when a sailboat changes course, as the rope stays fair and avoids twisting. The additional bottom becket provides an attachment point for the rope’s dead-end when building a multi-purchase system (for example, a 2:1 or 4:1 tackle with two blocks). This makes the block very versatile – it can be used on its own or as part of a more complex rigging assembly to multiply force.

Variants & Applications: The Finmax Speed Hard single block comes in two sizes, aimed at different boats and load requirements:

• Small Block (35 mm sheave, code 04997): For 3–8 mm ropes, approx. 800 kg breaking load. Ideal for small sailboats (4-6 m) and performance dinghies. Recommended uses include spinnaker or jib sheets, halyards for smaller sails, and various control lines on board light yachts. It can also be paired in a double-block setup (tackle) for mainsheet control on dinghies, providing extra purchase via the becket.
• Large Block (50 mm sheave, code 04911): For 6–12 mm ropes, approx. 1400 kg breaking load. Excellent for larger yachts (6-9 m) and higher-load scenarios. Ideal applications – as a primary mainsheet block, a bowsprit block for gennaker or spinnaker sheets, or in a vang/multi-purchase system for heavier sails. Using the becket, you can create 2:1 tackles for headsails or the mainsail, which reduces effort when trimming sails on medium to big boats.

The Finmax Speed Hard series guarantees reliable performance under sail – these blocks withstand sudden gusts and heavy strain without sacrificing smooth operation. With this single swivel block with becket, you get a combination of low weight, high strength, and convenient functionality. Whether you’re a recreational sailor upgrading your boat’s rigging or a racing skipper seeking dependable hardware, this Finmax block meets your demands for quality and durability in every situation.
