Published Design Ratios for the Malo 50

1. Sail Area/Displacement Ratio: 15.9

• Less than 16 would be considered under-powered;
• 16 to 20 would indicate reasonably good performance;
• Over 20 suggests relatively high performance.

2. Ballast/Displacement Ratio: 44.5

• Under 40: less stiff, less powerful
• Over 40: stiffer, more powerful

3. Displacement/Length Ratio: 275

• Under 100: Ultralight
• 100 to 200: Light
• 200 to 275: Moderate
• 275 to 350: Heavy
• Over 350: Ultraheavy

4. Comfort Ratio: 31.9

• Under 20 indicates a lightweight racing boat
• 20 to 30 indicates a coastal cruiser
• 30 to 40 indicates a moderate offshore cruising boat
• 40 to 50 indicates a heavy offshore boat
• Over 50 indicates an extremely heavy offshore boat

5. Capsize Screening Formula: 1.8

• Under 2.0 (the lower the better): Better suited for ocean passages
• Over 2.0: Less suited for ocean passages

Summary Analysis of the Design Ratios for the Malo 50

1. A Sail Area/Displacement Ratio of 15.9 suggests that the Malo 50 will need a stiff breeze to get her going. In light conditions, unless you've got plenty of time on your hands, motor-sailing may be the way to go.

2. A Ballast/Displacement Ratio of 44.5 means that the Malo 50 will stand up well to her canvas in a blow, helping her to power through the waves.

3. A Displacement/Length Ratio of 275, tells us the Malo 50 is a moderate-to-heavy displacement cruiser, which means she'll carry a reasonable amount of cruising gear without it having a dramatic effect on her performance. Many of today's sailboats intended for offshore cruising fall into this displacement category.

4. Ted Brewer's Comfort Ratio of 31.9 suggests that crew comfort of a xxxx in a seaway is similar to what you would associate with the motion of a moderate bluewater cruising boat - a predictable and acceptable motion for most seasoned sailors.

5. The Capsize Screening Formula (CSF) of 1.8 tells us that a Malo 50 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
