The Foils
The lightning is blessed in having a proper centreboard, a feature greatly appreciated when sailing in restricted depths, or during a capsize.
The centreboard and rudder blade are all moulded by the manufacturers GRP. A variety of rudder stocks have been used, some made by GRP, some by RWO and a few others, the design is the same and the rudder is always in the correct place with the leading edge vertical.
The size and shape of the rudder make it harder to stall than some other single-handers, which contributes to the good handling characteristics.
