Preheat oven to 325ºF. Place ham, fat side up, in roasting pan. Pour 1 inch of water into pan. Roast ham 1 1/2 hours.
For glaze, in a saucepan over medium heat, boil sugar and vinegar together 5 minutes. Add orange juice and simmer mixture until reduced by a third. (It should appear slightly syrupy.)
Remove mixture from heat; add rosemary, lime juice and salt and pepper to taste. Mix well, then add butter and stir gently until melted and well-incorporated.
Remove roasting pan from oven every 10 minutes or so, and brush generous amount of glaze all over ham, until crust is golden-brown and bubbly, about 30 minutes.
