In his latest journal entry Webb Chiles explains the reason for loose-footed sails on Drascombes.
I once met John Watkinson, the Drascombe designer, and asked him about the loose footed sails.
He replied: “I didn’t want to hear the sound of a boom hitting my wife’s head.”
That is an exact quote. Not “I didn’t want a boom to hit my wife’s head.” No. John didn’t want to hear the sound.
His wife was present and didn't seem to mind.
