I've hired either Melody 1 or Melody 2 about seven times over the last few years. There are subtle differences between each of the four. Small things like the helmsmen's seat and wheel, finish of the kitchen units, placement of the sink and drainer etc. If I remember rightly Melody 1 has a double at the front with a small seat like on San Remo. Melody 4 doesn't have the sink in the forward cabin or the sloping handrails at the back. The boat handles really well, which makes it a joy to hire solo. With 360 degrees of glass and a sliding sunroof the boat is light and airy and with the Nanni engine aft quiet too. Pete
