As delivered, our Prout Escale lacked a proper charging system, the wiring was undersized and/or unfused, circuit breakers did not match their loads, instruments would drop out when the engine was started, the starter battery would be depleted by the inane contactor system, etc... the list goes on. After several years of finding problems hidden in various parts of the boat, "Prout Catamarans" and electrical quality have become an oxymoron for me. At least current US customers seem to be shielded from the worst of it by Advanced Yachts (the US distributor) and their dedicated employees.
