In a saucepan, bring cranberries, sugar and water to a boil. Reduce heat and cook until berries burst. Strain through a food mill or sieve into a large bowl. Add gelatin, lemon juice and orange juice. Cool until mixture coats the back of a spoon.
In a small bowl, whip cream until soft peaks form. Add confectioners' sugar and vanilla; whip until stiff peaks form. Fold into cranberry mixture. Chill until set. Yield 8 to 10 servings.
