I'm going to be two up unless it's really light air.
Hey, here's something we have not discussed, since the boat is rated the same uni or sloop, can we change configuration during the regatta? ie. windy, bring crew and jib one day, then if the next day is light, leave them on the beach?
According to class rules No you cant.

Tradewinds is a two day event. That said if you sail uni on saturday you must sail uni on sunday.
