Rutgerson's 60mm series blocks are a more robust option for medium and larger sailboats, where rope loads are higher than on smaller boats – the 60mm size range is a popular choice for blocks for genoa trim lines, sail lockers and winch pre-steering, for example.
The range includes a basic block (B300601B) and a version with a fixed toggle connector (B300601BF12) and a movable toggle (B300601BT), which allows the block to turn slightly according to the direction of the load and reduces lateral stress at the attachment point. The model with a hunsvot (B300602B) and the block with a lock (B300603B) allow the rope to be locked in place without a separate rope lock, and the combination model with a lock and hunsvot (B300604B) offers both features in the same block. The violin blocks (B300621B and B300622B with hunsvot) are designed specifically for double rope solutions, such as controlling two trim lines of a genoa from the same point.
Rutgerson is a Swedish manufacturer known for its durable aluminum construction and bearings that withstand both salt water and repeated UV exposure. Choosing the right block model depends on the application: a fixed model is suitable when the direction of the rope remains constant, while a model with a toggle is a better choice when the direction of the load varies, for example due to the trim of the sail. Always check the maximum load of the block in the manufacturer's table before installation to ensure that it corresponds to the actual load on the rope and the application.
The Rutgerson 60mm block bearing is designed to withstand repeated, heavy loads without the rotation becoming stiff over time – regular rinsing with fresh water after a season will significantly extend the bearing life in a saltwater environment. The Hunsvot model allows the block to rotate slightly with the direction of the load, which reduces lateral stress on the attachment point compared to a fully fixed installation. The advantage of the lock model is particularly evident in situations where the rope needs to be held in place without constant hand holding, for example in trim rigging during extended sailing. Fiddle blocks are particularly useful when there is a lack of space on deck and there is no room for two separate blocks side by side – one attachment point can then guide two ropes neatly side by side.
Check the maximum load of the block from the manufacturer's table before installation to ensure that it corresponds to the actual load on the rope on your boat.
The Rutgerson aluminum hull withstands both saltwater and repeated UV exposure over several sailing seasons with careful care.
