    I have always been puzzled about why the pumping rule is misread. It has always said when the sheet is pumped it must be through the block on the boat and at least three parts of the mainsheet – I may be wrong but I do not recall it ever saying that the sail may only be trimmed through the block on the boat.
    This is not a mystery or something that has been cooked up and hidden for years but a rule to control pumping to promote planing – from way back when more than one pump on a wave was acceptable.
