In a large pot of boiling salted water, cook the potatoes until tender but still firm, about 30 minutes.
Drain and cut into 1⁄4-inch slices. Transfer to a large bowl and add the parsley, chives, and tarragon. Set aside. In a small bowl, combine the oil, vinegar, salt, pepper, and sugar. Pour the dressing onto the potato mixture and toss gently to combine.
Taste, by adjusting the seasonings, if necessary. Chill for 1 to 2 hours before serving.
