1. Sail Area/Displacement Ratio: 15.2
2. Ballast/Displacement Ratio: 29.3
3. Displacement/Length Ratio: 288
4. Comfort Ratio: 48.3
5. Capsize Screening Formula: 1.6
1. A Sail Area/Displacement Ratio of 15.2 suggests that the Irwin 52 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 29.3 means that a sailboat like the Irwin 52 (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 288, tells us the Irwin 52 is clearly a heavy displacement cruising boat. You can load her down with all your cruising gear and equipment and it will hardly affect her waterline. Not an ideal choice for coastal sailing, but she'll come into her own on an offshore passage in testing conditions.
4. Ted Brewer's Comfort Ratio of 48.3 suggests that crew comfort of an Irwin 52 in a seaway is similar to what you would associate with the motion of a heavy bluewater cruising boat. Pitching and rolling will be well damped - your cup of coffee on the salon table stands a reasonable chance of staying there in most conditions.
5. The Capsize Screening Formula (CSF) of 1.6 tells us that an Irwin 52 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
What other versions of the Irwin 52 were built?
There were two versions of the Irwin 52: the standard version and the center cockpit version.

What sail plan and rigging options are available for the Irwin 52?
The Irwin 52 was originally designed as a ketch, with a mainmast and a mizzenmast. The mainmast had two spreaders and carried a mainsail, a genoa, and a staysail. The mizzenmast had one spreader and carried a mizzen sail and an optional mizzen staysail. The sail area was about 1,400 square feet. Some owners opted for a cutter rig instead of a ketch rig, with a single mast and three headsails. The cutter rig had more sail area and better performance upwind, but less stability and maneuverability downwind.
