Design Ratios: The Key Performance Indicators

The Crealock 37, a sailboat designed by renowned maritime designer W.I.B. Crealock, has long been a favorite amongst sailing enthusiasts. Its timeless design combined with its rugged construction and outstanding performance make it an attractive option for those looking for a true blue-water cruiser.

Analyzing the design ratios of the Crealock 37 gives a clear understanding of its potential performance.

  • The Sail Area/Displacement (SA/D) ratio is 16.41, which is indicative of a moderate cruiser. This ratio signifies the balance between the sail area and the boat's weight, with a higher number generally indicating a faster, more performance-oriented boat.
  • The Ballast/Displacement ratio of the Crealock 37 is 40.21%. This demonstrates the boat's ability to resist capsizing, with a higher number indicating better stability. This is a crucial feature for those looking to undertake long-distance cruising, particularly in rough conditions.
  • The boat's Displacement/Length (D/L) ratio is 324.48. This is slightly higher than some other boats in its class, indicating a heavier boat with more volume. This translates into more onboard storage and living space, a significant advantage for those planning extended trips at sea.
  • The Comfort Ratio of the Crealock 37 stands at 33.95. This indicates the boat's motion in a seaway, with a higher number representing a more sedate and comfortable ride. This makes the Crealock 37 well-suited for cruising rather than racing.
  • A Capsize Screening Formula (CSF) of 1.73 suggests that the Crealock 37 has good seaworthiness. The lower the number, the better the boat's theoretical capsize resistance, making it a safe choice for offshore voyages.

So what are the Design Ratios, and how are they formulated?

Alternative Rigs

The original design of the Crealock 37 is a cutter rig, but alternative options are available. These include a sloop and a ketch design, each with its unique benefits and considerations for cruising performance and handling.

Pros & Cons

The Crealock 37 is renowned for its build quality and attention to detail. The boat is sturdy, well-constructed, and built to last, as evidenced by the many vintage models that are still sailing today.

In terms of strengths, the Crealock 37 scores highly for its safety, comfort, and efficiency. The boat's design ratios indicate good stability and performance, while its construction quality ensures reliability and longevity.

However, like all boats, the Crealock 37 does have some weaknesses. Some users find the boat a bit challenging for single-handed sailing due to its size and weight. Others may prefer a lighter, more performance-oriented boat.

Despite these minor criticisms, reports from seasoned sailors and accredited marine journals suggest a high level of satisfaction with the Crealock 37. Many praise its sturdy construction, comfortable interior, and excellent seaworthiness, confirming its reputation as a top choice among sailors.

The Secondhand Market

The Crealock 37 is also popular on the secondhand market, with prices typically ranging from $75,000 to $150,000. The price can vary significantly depending on factors such as model year, condition, and included equipment.

What is the history of the builders of the Pacific Seacraft 37 and is the company still in business?

The Pacific Seacraft 37 was originally designed by William Crealock for Cruising Consultants, a company founded by Henry Mohrschladt and Mike Howarth in California in 1976. They sold the design rights to Pacific Seacraft in 1980, which was also founded by Mohrschladt and Howarth in California in 1976. Pacific Seacraft continued to build the boat until 2011, when it filed for bankruptcy protection and closed its doors.

In 2012, Pacific Seacraft was acquired by a new owner, Stephen Brodie, who relocated the company to North Carolina. The company resumed production of some of its models, but not the Pacific Seacraft 37.
