Perhaps better than any other designer, John L. Hacker perfected the bullet shaped hull in many of his designs. Lockpat II is the most dramatic example. Muskoka wooden boaters will point to the Greavette Streamliner and Curlew as local examples of this shape. Lockpat II was built in 1931 for Dick Locke. At 40′ long, she is one of the longest of her kind. She was originally powered by a Packard 1A-2-25 Aero Engine with four valves per cylinder. Two of eleven versions were converted to marine. Lockpat II was designed to attain speeds in excess of 60mph.
