Summary Analysis of the Design Ratios for the Hallberg-Rassy 41

1. A Sail Area/Displacement Ratio of just 15.9 suggests that the Hallberg-Rassy 41 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 38.4 means that a sailboat like the Hallberg-Rassy 41 (which doesn't have a stiffness-enhancing bulb keel), is likely to benefit from being reefed early to keep her sailing upright in a moderate breeze.

3. A Displacement/Length Ratio of 244, tells us the Hallberg-Rassy 41 is a moderate displacement cruiser, which means she'll carry all your cruising gear without it having a dramatic effect on her performance. Most of today's sailboats intended for offshore cruising fall into this displacement category.

4. Ted Brewer's Comfort Ratio of 38.6 suggests that crew comfort of a Hallberg-Rassy 41 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 1.7 indicates that a Hallberg-Rassy 41 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
