The Series 19 is an update of Ronstan's proven small boat track and slide systems. The brass slides of the earlier series have been replaced with glass-fibre reinforced polymer and the track is now alloy instead of stainless steel. This means the fittings are only half the weight of the earlier system but provide identical load capacities. The composite slides also have lower friction when running in the track.
Ronstan traveller systems deliver the performance required for optimising sail trim, responding quickly to changing conditions and getting the right balance from the loads on sails, rig and foils. Ronstan systems have been put to the test by Volvo Ocean Race teams, Vendée Globe challengers, and the professionals on the prestige international circuits who demand the highest performance and dependability, with no room for compromise.
The I-Beam series is a simple, reliable range of travellers. Strong stainless steel bodies with flared sides and angled ball bearing wheels provide high load capacity and smooth operation. Wheels and ball bearings are made of stainless steel and tracks are anodised aluminium.
For small keel boats and sportsboats, T-Track jib lead and spinnaker pole slides are a great blend of performance and functionality in a simple, efficient package. Composite slide bodies with plunger stops run on anodised aluminium track, and allow quick and easy manual adjustment.
The Series 25 car body is moulded 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.
Sleek styling and the positioning of the attachment pin provide a low lead aft from 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.
Composite jib lead cars continue the design philosophy of the award winning Ronstan BB and RT Orbit Blocks™, with virtually all metal components of Series 25 T-Track cars now replaced with high-tech polymers and fibre equivalents. The car design has been modelled and optimised 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 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. The ‘Racing’ track has 25mm (63/64”) stop hole spacing for even more precise control of the car position and sheeting angle.
