The ACS (Anti-Capsize System) is an innovative automatic and autonomous safety system designed to overcome the problem of multihull capsizes.


Automatic: When a critical angle of heeling or pitch poling is exceeded the ACS acts directly by progressively releasing the sails.
Autonomous: The ACS depends on no external equipment or instrumentation(electronic or computerised) thus ensuring a high level of stability and reliability. Negligible consumption on standby (0.010A) allows the system to remain switched on without risk of electrical overconsumption. 

Presentation: The result of two years of development and trials, in particular in the high performance area of racing multihulls, the Anti-Capsize System was patented in 2003 by Marc and Roger Ganovelli. On the market since 2004, the system has satisfied all available tests for racing multihulls. Custom-fitted aboard each vessel, the ACS offers indispensable automated safety in the search for efficient and reliable performance on multihulls: automatic release of the sails when pre-set angles (configured to measure) of heeling and pitch poling are exceeded.

To date, the ACS has been installed on several of the 60-foot trimarans participating in the Route du Rhum 2006 and in other ocean races:

 GROUPAMA    Franck CAMMAS  (trimaran 60-foot ORMA) 
 BANQUE POPULAIRE    Pascal BIDEGORRY    (trimaran 60-foot ORMA)
 BROSSARD      Yvan BOURGNON   (trimaran 60-foot ORMA)
 SOPRA GROUP     Antoine KOCH   (trimaran 60-foot ORMA)
 REGION GUADELOUPE    Claude THELIER    (trimaran 60-foot ORMA)
 IDEC     Francis JOYON  (trimaran 29.70 m Gclass)

Other installations are currently in progress.

During the Route du Rhum, skippers and media commended its efficiency and performance.

This is an indispensable safety system for both racing and cruising vessels. Minimal in size, the ACS is suitable for all types of configuration (hydraulic or electrical).
