FB29.190 system, 190 mm sliders. All components’ dimension and the distances of the sail from the mast are found in the sheet Full Batten Systems – Measures.
Designed for large boats and for mainsails with a large roach, they offer the high strength of HS Fibre Guides (for tension load) and the low friction of the Torlon ball bearing (for compression). Maximum load because the HS fibre guides give excellent resistance to the main pull loads despite the compact size of the carriages.
Each batten end fitting is attached to a slider with a triaxial joint to ensure that the batten can freely orient itself under all points of sail. At least one simple slider should be attached to the sail with nylon webbing between two battens. A headboard is attached to the sail with webbing and is secured to the slider (double) with a clevis pin which allows the headboard to pivot and to be removed. Self-captive bearings: it’s impossible for the bearings in the slider to come out, so it’s possible to take off the sliders from the track.
Choice of the track. For larger boats and a Fibreball system choose an FB 29 system with 29x11 track. These systems combine the high resistance of fibre and the low friction of ball bearings, for boats up to 100’.

Position of the mast. Mainly depending on the position of the mast when the track will be installed, one chooses the short or the longer track length. Antal realizes bars lengths of 2 and 3 meters. A 3 meter long track is recommended if the mast is horizontal (non mounted masts), while the 2 meter long track is easier to install when masts are in the vertical position (mast already on the boat). Mounting type. Mounting type depends on the mast’s characteristics. Antal tracks are realized for different types of mounting. Choose a track for slugs in case of masts with groove. Masts without a groove or wooden masts will require installation with screws or glue, being glue a good solution for tracks on a carbon mast. In the sheet information about 29x21 Antal track all technical info about track mounting are available. Hole distance. Available single and double hole distance, for the different demands of ease of installation and holding strength of the track.
