Review RONSTAN Series 60 Stand up Block Available

The Ronstan RF872 60 Stand-Up Block is a high-performance sailing accessory designed for optimal sail control and ease of use. This block is part of Ronstan's RF Series, which is renowned for its durability, smooth operation, and sleek design.

The RF872 is a 60mm (2.36 inches) diameter stand-up block, making it an ideal choice for larger sailboats or heavy-duty applications. Its design allows the block to be easily stood on for applying pressure when trimming sails, providing excellent leverage and control.

The block features Ronstan's patented "Self-Gripping" sheave technology, which ensures a secure and reliable grip on the sail control line. The sheave is made from marine-grade Delrin, a high-performance polymer that offers superior wear resistance and low friction. The sheave's large diameter and unique shape facilitate smooth and efficient line travel, even under heavy loads.

The RF872's body is made from solid, one-piece extruded aluminum, providing exceptional strength and rigidity. It is anodized for added durability and corrosion resistance, ensuring the block can withstand the harsh marine environment. The block's large, ergonomic knobs provide a comfortable grip and easy adjustment, while its sleek, streamlined design reduces wind resistance and drag.

This stand-up block is designed to be used with 7/16 inch (11mm) or 5/8 inch (16mm) diameter lines, and it can be easily mounted using the included stainless steel mounting hardware. The hardware features a captive nut design, ensuring the nuts stay securely in place and do not fall out during use.

In summary, the Ronstan RF872 60 Stand-Up Block is a high-quality, high-performance sailing accessory that offers excellent sail control, smooth operation, and durability. Its self-gripping sheave, solid aluminum construction, and ergonomic design make it an essential tool for sailors looking to optimize their sail trim and improve their boat's performance.

The Ronstan RF872 60 stand-up block is a popular choice among sailors due to its durability, functionality, and design. However, like any other product, it has its pros and cons. Let's examine each in detail.

1. High-quality construction: The Ronstan RF872 is made from high-density polyethylene (HDPE) material, which makes it robust and resistant to UV radiation, chemicals, and impact. It is also self-lubricating, ensuring smooth and reliable operation.

2. Versatile application: This stand-up block is suitable for a wide range of applications, including mainsheet, jib sheet, spinnaker sheet, and halyard. Its large diameter (60mm) makes it ideal for heavy-duty use.

3. Easy installation: The Ronstan RF872 is easy to install, as it does not require any maintenance or adjustment. It can be used as a permanent or temporary block, depending on the user's preference.

4. Lightweight: Despite its robustness, the Ronstan RF872 is relatively lightweight, making it easy to handle and transport.

1. Expensive: Compared to other stand-up blocks in the market, the Ronstan RF872 can be quite expensive. Its high-quality construction and versatility come at a premium price.

2. Limited size options: The Ronstan RF872 is only available in one size (60mm), which may not be suitable for all applications. Smaller or larger sizes may be required for specific sailing conditions.

3. May not fit all boats: The Ronstan RF872 is designed to fit standard 7/8" sheaves, but it may not fit all boats. It is essential to check the compatibility of the block with the boat before making a purchase.

4. May require additional hardware: Depending on the application, the Ronstan RF872 may require additional hardware, such as shackles, cleats, or lines, which can add to the overall cost.

The Ronstan RF872 60 stand-up block is a high-quality, versatile, and durable product that is suitable for heavy-duty sailing applications. Its self-lubricating HDPE construction ensures smooth and reliable operation, and it can be used for various sheet and halyard applications. However, its premium price and limited size options may make it a less attractive choice for some sailors. Ultimately, the decision to buy the Ronstan RF872 depends on the user's specific sailing needs and budget.

If you are looking for a high-quality, robust, and reliable stand-up block for heavy-duty sailing applications, the Ronstan RF872 60 is an excellent choice. Its self-lubricating HDPE construction ensures smooth and reliable operation, and its versatility makes it suitable for various sheet and halyard applications. However, if budget is a concern, or if you require a smaller or larger size, other stand-up blocks in the market may be more suitable for your needs. It is essential to consider all the pros and cons carefully before making a purchase.
