Minor Correction
The Lapworth designed Cal 40 was the break through boat. Winning regattas the world over including several Transpac races. The Cal 40 class is experiencing a comeback with many people buying and restoring these "plastic classics". The Hunt designed Cal 39 is a later product and is a very fine and fast cruising boat.Link to Cal 39 review: http://www.boats.com/news-reviews/article/perry-design-review--cal-39Link to Cal 40 site: http://www.cal40.com/Both are great boats.
