    In the moths in late 80's , the Uk sail shape was tending to go towards square heads / more roach , with AUS shapes more triangular - apparently due to the lighter UK winds/ stronger AUS winds.
    However when Aussie sailors tried the UK style shape, they found that it was better in strong winds too. Now the sails are universally big roach fat head sails.
    More triangular storm sails with same luff but less roach and less area. were sometimes used for strong winds up until the mid 90's, but hull and T-foil developments mean that no-one ever uses a storm sail now. They were fastish upwind, and safe but slow downwind. Using a T-foil meant that it was safe downwind with a big fat head sail - so no need for storm sails.
