Sailing is an exciting and captivating hobby that is gaining more and more popularity. Like many other marine hobbies, sailing is versatile; there is almost nothing you can’t do on the water if you own a sailing boat. Whether you want to take your family and friends for a memorable day out at sea, explore the surroundings, try out new fishing spots, or simply chill on a sunny day, your sailboat will assist you on every step of your journey.
No matter how much of an advanced sailor you are, you can’t have a 100% comfortable and safe sailing trip without reliable gear. Malfunctioning or low quality gear can jeopardize the whole adventure, putting the safety at risk. To avoid any risks, replace any faulty component in time. Some of the most essential sailing hardware are sailing blocks. We have a variety of sailing blocks for almost any application, so if you need a replacement for your broken block, look no further. Additionally, you can upgrade your current sailing equipment when more strength, faster running, and easier trimming of the lines are required.
Lines slide through blocks to make a directional change of up to 180 degrees with minimal friction or to create a purchase tackle. In essence, a sailing block is a housing that has one or more sheave pulleys enclosed between cheeks. You can find single, double, and triple sheave configurations. Depending on the block’s maximum work load, sailing blocks also come in traditional and high load varieties. Available in many sizes, materials, and models, sailing blocks are an indispensable part of sailing hardware. Whether you are racing or cruising, we have the right block for you and your sailboat.
When you’re out on the water sailing, the last thing you want to happen is your sailing equipment to fail you. With that in mind, we provide only durable sailing blocks you can rely on. Featuring optimal strength to weight ratio and reliable bearings, our sailing blocks ensure easy and smooth running under the highest loads. Whether you have a large cruising yacht or a dinghy, we have a versatile range of blocks to suit just about every need. Our team goes the extra mile to provide sailing blocks designed to meet the demands and expectations of dedicated sailors, without putting extra strain on their budget.
