Another reason for not having wings is that they need to be twice the width ytou loose in the boat by making it thinner for slightly less righting moment.

Consider an 8 foot wide boat, it has it's pivot about the leeward hull with no wings so you have an 8 foot pivot.

Make the boat 6 feet wide and you need to add 2 foot wings each side to get back to an 8 foot pivot. BUT you still are loosing out as the leeward wing is acting against you as it is the other side of the pivot.

Wings are not usually a good option.
