1. A Sail Area/Displacement Ratio of 15.8 suggests that the Luders 36 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 35.0 means that a sailboat like the Luders 36 (which doesn't have its ballast concentrated in a bulb at the foot of a deep keel), is likely to benefit from being reefed early to keep her sailing upright in a moderate breeze.
3. A Displacement/Length Ratio of 429, tells us the Luders 36 is firmly in the ultra-heavy displacement category. Load her up as much as you like and her performance will be hardly affected, not that it was ever startling. Few if any sailboats are built to this displacement category these days - but they remain popular with some long-distance sailors.
4. Ted Brewer's Comfort Ratio of 37.1 suggests that crew comfort of a Luders 36 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 tells us that a Luders 36 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
