VIADANA, HYE, SEA SURE blocks

What is the difference between a single sheave block and a double sheave block?

Single sheave blocks are ideal for light maneuvers and for deflecting lines at a limited angle. Double, triple, or quadruple sheave blocks offer greater mechanical advantage, making them suitable for maneuvers that require more effort, such as adjusting the mainsail or jib. The choice depends on the expected load and the complexity of the running rigging system.

How do I choose the right block for my boat?

To choose the right block, carefully consider the diameter of the rope that will be used, the maximum expected working load, and the type of maneuver that will be performed. Consult the technical data sheets of Viadana, HYE, and Sea Sure to identify the model that best suits your needs. If in doubt, do not hesitate to contact our team of experts: we will be happy to provide you with personalized advice.

Can I use a Viadana block for my Laser's sheet?

Absolutely yes. Viadana micro-blocks are particularly suitable for light dinghies such as the Laser, Optimist or 420, thanks to their compact size and light weight. Make sure that the sheave diameter is compatible with the diameter of your sheet to ensure smooth and frictionless operation.

Are plastic blocks resistant to salt water?

High-quality plastic blocks, such as those produced by Viadana, HYE, and Sea Sure, are made with technopolymers that are resistant to UV rays, salt water, and atmospheric agents. However, it is always advisable to rinse them regularly with fresh water to remove salt residues and prolong their lifespan. Proper maintenance helps preserve their performance and prevent corrosion.

What is the importance of a block's breaking load?

A block's breaking load indicates the maximum force the block can withstand before failing. It is essential to choose a block with a breaking load appropriate to the expected working load, taking into account a safety margin to avoid sudden breakages and ensure crew safety. Always consult the manufacturer's technical specifications for an informed choice.
