Most European boats don’t come close to Hatteras quality and layout. I think the 2004-2014 80’ Hatteras is one of the best MY in that size range. The latter Panaceras 75, 90 and 100 are great boats too. Another good boat in that size range is the 84 Lazzara. I ran one for 5 years, fantastic layout and excellent quality. Not as good in rougher stuff as the 80 Hatteras but burns 20 GPH less at 22kts...
Italian boats typically have flaky electrical systems especially azimuts and maintenance intensive Man engines. But the biggest issue is that they are not designed for the US market and how we use boats on this side of the pond. Most obvious are the frequent lack of rubrails and side boarding gates.
Because med mooring is so wide spread in Europe, boats rely on fenders whereas here with so many marinas using wood pilings, especially on the east coast and Bahamas, not having a rub rail means you d better have a painter on your speed dial...
Boarding is even worst as they rely on stern passerelles. When alongside a fixed dock or a finger pier, a passerelle is useless. I constantly see folks struggling on and off those flashy European boats...
