Our 15,455-pound tester was powered by triple Yamaha F350 outboards. Rigged with a hardtop and tower, it sped to nearly 60 mph and ran smooth through confused seas. Our tester arrived with Yamaha's Helm Master system (boatingmag.com/helm-master), which features joystick steering for close-quarters maneuvering, digital throttle and shift, digital wheel steering, push-button speed control, engine synchronization and auto-trim capability, among other features. The 355T's big center-console offers excellent weather protection, thanks to a tempered-glass windshield. Its hydraulically operated forward panel slides down, ushering in fresh air. The console accommodates a pair of 15.5-inch multifunction displays and a brace of Yamaha's 6Y9 Command Link Plus gauges. A tower helm station is available ($23,077).
