The Delta Hydrosonic Special was a high-performance powerboat designed by Sonny Levi, a famous boat designer and powerboat racer. The boat was built in the 1960s and 1970s and was known for its innovative design and impressive speed.

The Delta Hydrosonic Special was a hydroplane-style boat, meaning it was designed to ride on top of the water rather than plow through it. The boat was constructed using lightweight materials, including aluminum and fiberglass, to minimize weight and maximize speed.

One of the most unique features of the Delta Hydrosonic Special was its hull design. The boat’s hull featured a stepped design, which helped to reduce drag and improve stability at high speeds. The boat also had a distinctive winged keel that further improved stability and handling.

The Delta Hydrosonic Special was powered by a range of high-performance engines, including V8 and V12 engines from companies like Ferrari and Lamborghini. The boat was known for its impressive speed and maneuverability, and it was a popular choice among powerboat racers during its heyday.
