The hull lines drawn for the 475 later carried forward to the Nautitech 47 and the then-new 482. Their reuse is a telling sign that the platform’s underwater shape was considered sound long after the deck and cockpit had been reworked by Multicoques Mag.
Design and Construction
The 475 is a solid-fiberglass catamaran with a 25-foot beam and 4-foot draft. It carries a single 50-horsepower Volvo Penta MD 22L diesel.
On the revised version, a grafted stern platform lengthened the cockpit, while a superstructure added to the transom kept foot traffic moving smoothly around the seating area. However, that same stern structure meets the sea directly when the boat rears up in steep chop.
Cockpit and Accommodations
The revised exterior table was completely redesigned, improving conviviality on deck. Together with the longer stern platform, it made the cockpit more welcoming and easier to move around.
With 210 gallons of water and 110 gallons of diesel, the 475 was sized for extended stays aboard.
Rig and Handling
The modified 475 adopted a rigid bimini that incorporates the mainsail sheet. The trade-off is the sightline: the mainsail is no longer visible from the winch dedicated to its adjustment. Trim changes therefore have to be judged by feel or by calls from the crew rather than by direct view.
Known Issues
Two drawbacks stem from the modified version’s aft redesign. Its stern superstructure tends to strike the sea when the boat pitches up in sharper chop, and the mainsail can’t be seen from its trimming winch. Both are artifacts of the later modification, not the original hull.
Verdict
The Nautitech 475 is a charter-bred catamaran whose hull design lived on in later models even after its deck and cockpit were revised. The modified version gained cockpit space, better flow, and a more convivial exterior table, but those changes brought two clear compromises: a stern structure that can slam the sea in steep chop and a lost sightline from the mainsail-trimming winch.
Pros
- Hull design reused on the Nautitech 47 and 482, suggesting a sound underwater shape
- Redesigned exterior table and stern platform improve cockpit conviviality and flow
- Rigid bimini integrates the mainsheet for sheltered helm control
Cons
- Modified-version stern superstructure strikes the sea when the boat rears in steep chop
- Mainsail is invisible from its dedicated trimming winch on the modified version
