Heysea Yachts Deliver Second Zoom 72 Yacht The full GRP-built Heysea Zoom 72 has now made it to another owner, an Asian client. This is the second hull in this new series by Chinese builder Heysea Yachts and is tailor-made for the Asian market. The yacht features two interior decks (main and lower) as well as a flybridge area. Below decks twin Volvo 725 horse power engines power the craft to a top speed of 21-knots. If you want to extend your range, a continuous 10-knots should ensure a 700 nautical mile range.
