Perhaps the most remarkable aspect of this Donzi's performance can be found in its turning ability. First, each rudder has a separate Hynautic hydraulic ram rather than one for both. Second, the wheel takes but three-and-a-half turns lock to lock. And third, at top speed the Donzi carves a 180-degree turn in about three boat lengths. The astounding part is that it loses only about 3 knots in the process. And steering is a one-finger effort. Stopping from full speed when you chop the throttle happens in just over five boat lengths - another testament to the slipperiness of the bottom. Few other 58-footers can get up on plane with only one engine, but this Donzi did and ran at 11 knots.
Perhaps the cleanest, best laid-out helm station I've ever seen on a sport-fisherman can be found on the Z-58. This command island, open to forward seating on both sides, has a modest wraparound to the console and the overhead instrument boxes. Consequently, the helmsman can sweep every instrument and display on the bridge without ever moving his head.
Forward of the console Donzi has placed a unique island seat on centerline and a corner seat in each forward corner. I can't imagine owning enough gear to fill the available storage area on the flybridge, let alone the rest of the vessel. Several other features particularly impressed me. Rod storage has been provided in the side coamings behind clear Lucite hatches, and the access ladders to the tuna tower are inside the flybridge rail so you don't have to feel like you're hanging out over oblivion to climb upward.
Every silver lining has a cloud, however. I don't care for having the hatch for the flybridge ladder directly behind the helm seat. Though it sports a rail around two sides, I couldn't get over the feeling of an accident waiting to happen.
