Devon, the class rules DO allow wings - they must still fit within the boxrule though. So you arrange the wings so that one is always 'kicked up' and you get a slightly better righting moment than a full width F16 without wings. However you're penalised in that they are not part of the platform weight so your boat will always be over and you have the added complexity of the arrangement and the chance of something going wrong.
It may well be that a winged F16 could be faster but that is the beauty of the class - someone has to try it first before others will follow!
