Italian jet drive specialist Castoldi knows a thing or two about speedy superyacht tenders, and the 6.24 metre Castoldi JT21 is the fastest in its collection, driven by a 260hp Yanmar engine to a top speed of more than 40 knots. The central helm position leaves room for up to 12 guests sitting forward and aft, while the jet drives are not only safer for watersports and swimming, but they also reduce the risk of running aground in shallow waters.
