Summary Analysis of the Design Ratios for the Morgan 41 Out Island

1. A Sail Area/Displacement Ratio of just 15.5 suggests that the Morgan 41 Out Island is just a tad under-powered and 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 37.0 means that a sailboat like the Morgan 41 Out Island (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 261, tells us the Morgan 41 Out Island 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 29.7 suggests that crew comfort of a Morgan 41 Out Island in a seaway is very close 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 1.9 indicates that a Morgan 41 Out Island would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
