Derived from the videos the fleet has analysed of this model. ▶ marks open the moment aboard.

The Hallberg-Rassy 31 is a fractional sloop designed by German Frers and built by Hallberg-Rassy from 1992 to 2009. It measures 9.62 meters LOA with a 3.30-meter beam, a 1.71-meter draft, and displaces 4500 kg.0:34 Early 1990s models were delivered without a fixed windshield, while later models included a Volvo Penta 2020 engine. A shallow draft keel option was also available, reducing the draft to 1.41 meters.0:34 John Neal, a sailing instructor with 430,000 miles sailed, identified a passing Hallberg-Rassy 31 as a sister ship to a boat he sailed for 11 years and 44,000 miles.0:54
