Pete Melvin has come a long way since the first boat he built as a 6-year old, which, unfortunately, would not float.
But he didn’t let that initial setback discourage him. Now a respected and successful sailor, designer and engineer, Melvin has been hired by the Defender and Challenger of Record of the 35th America’s Cup and tasked with coming up with the class rule for a second consecutive time.
“The process is to listen to the requests and desires of the Defender and Challenger of Record, which includes reducing the costs of the boats and in fact of the entire campaign. On the boat side, that means smaller boats, with less crew, and less personnel involved in design, logistics, and reduced construction costs,” Melvin says.
“We are looking at concepts that are similar to the AC72 - a foiling cat with wingsail. The consensus from teams is that this was a good concept and we want a smaller version in the 60 to 65 foot range. We’re looking at various ratios of beam to length and wing size and power and running VPPs on those boats to see performance, speed, controllability etc.
