Composite jib lead cars continue the design philosophy of the award winning Ronstan BB and RT Orbit Blocks™, with virtually all metal components now replaced with high-tech polymers and fiber equivalents. The car design has been modeled and optimized using finite element analysis and rapid prototyping techniques to achieve maximum strength-to-weight characteristics. Orbit Block™ models use a Dyneema® Link which is 10 times stronger and lighter than steel, to provide the articulated connection between block and car.
The clever 2-piece car body is molded from a composite material that delivers low friction on the alloy track without the need for separate inserts. It also provides the required mechanical strength without the weight and corrosion drawbacks of metal parts. An integrated becket at the forward end of the car suits 2:1 sheet systems and the removable threaded pin allows easy fitting of alternate blocks and accessories.
Low Profile and Compact
Sleek styling and the positioning of the attachment pin provide a low lead aft for the lead block. The Dyneema® Link allows full articulation. The plunger stop button has a flush finish and the contoured form of the car eliminates the chance of lines and sails becoming snagged.
The ergonomic plunger stop toggle combined with low friction of the car body allows for easy one-handed adjustment. The toggle is located at the rear of the car for easy access from the cockpit on sports boats and small keel boats. An arrow is located on the side to indicate the position of the stop for repeatable settings. A new ‘Racing’ track has 25mm (63/64") stop hole spacing for even more precise control of the car position and sheeting angle.
Headsail sheet leads on boats up to 8m (26ft).
