Beautifully presented example of the highly regarded Predator 58 with A/C, which has been in the same family ownership for the last 17 years! She enjoys a very practical 6-berths in 3-cabin layout, 1 en-suite + guest heads.


Its not so often that you come across a boat which has so clearly been so much loved that it has passed in ownership from parents to one of their siblings but this is exactly what has happened with the now Dutch flagged WHY KNOT? (she was previously Swedish flagged), which has remained in the same family for seventeen of her twenty one years since she left the Sunseeker yard. Not surprisingly, the second generation of the family to be lucky enough to own this fantastic yacht is only selling their lovingly maintained and beloved yacht due to a lack of time to be able to continue to enjoy her (she has just 280 hours on her engines since 2007). With her classic good looks, excellent performance from her twin Detroit V8’s and her stylish mahogany wood interior, she would surely make for the perfect Mediterranean motor boat. The interior accommodation provides style, comfort and practicality with 6 berths in 3-double cabins (1 en-suite) plus a further guest/days heads. The cockpit and helm position provide a wonderful vantage point from which to enjoy your surrounds whilst underway and also when berthed/at anchor. Additionally, the useful tender garage hides away the Kawasaki Jetski which should provide hours of fun.
