CANTIERI COSTA SMERALDA
NIBANI 31

The Nibani 31's sea trial was performed with wind over 20 knots and moderately rough sea. They have shown to be excellent conditions for this seaworthy hull which will probably set the standard in its class. This sport-fisherman take advantage from the experience acquired by the Cantieri Costa Smeralda in building the well known Nibani range.

The Nibani 31 feature innovative concepts as well, and, in our opinion, is the most representative Nibani ever built. The boat looks larger than it is, whenever you look at it at berth or at sea, maintaining its sleek lines in both situations. In addition, the stability and the trim are always excellent. All this result in an outstanding seakeepness, compared to the boat's size, which I believe is one of the most valuable achievement of the Nibani 31. The boat has been designed and built perfectly and will surely be appreciated by the experienced yachtsman. Particular attention has been paid to practicability, so important on sport-fishing boats; comfort and habitability, on the other hand, were not disregarded and the boat is perfect for cruising as well.

Below deck the Nibani 31 has accommodations for up to four persons; a dinette, a completely equipped galley area and a spacious bathroom with teak floor and shower are the main features. Detailing is elegant and sober, transmitting to the boat a unique style happily combined with the beautiful hull and superstructure colors. The Nibani 31 is, in conclusion, a cruising sport-fisherman built, with particular style, by the renown Cantieri Costa Smeralda which ensure a positive quality to price ratio as well.
