Hi Mary, You use weight modification factors for any class that has a minimum crew weight restriction. If a class has none, then you do not apply the modifications because you cannot use something that does not apply. There are any number of reasons why a class may, or may not, choose to have minimum crew weights.



These mods are part of the Portsmouth Handicap so they do not apply to one design racing. By definition, you race boat for boat and do not need or use handicapping because each boat is the same as the other and no design differences have to be taken into account.



One reason the Wave class has no weight minimum is that we allow open sail design; as long as the sail measures within established limits you can have a fuller shape for the big boys and flatter shapes for the little folk.



Carol switched to Sail Wave scoring this season and, after becoming familiar with it, reports that it is very versatile and easy to use. She gives it two thumbs up! It does allow easy use of the crew weight mods.
