A versatile and innovative range of aluminum profiles
The two profiles are designed and extruded with the external track offering several choices for main sails. The track system works with bolt rope for racers, sliders for an easy-handle or full-battened sail for ocean cruisers very easily because they don’t have structural issue, you can always hoist the sail when the mast is bending.
Regarding the performance, the profile is stiffer thanks to the track; the inertia is calculated with the system. It’s also lighter than a profile with added track because we don’t need screws. Thus, it requires less maintenance with the track so the profile is better for a long term use.
