In 1983 most windsurfer sails were simple triangle shaped sails that maybe had one or two battens to stabilise the leech of the sail. But sailors were becoming more radical in their style and started to need sails that could perform in high winds and surf. The Neil Pryde HiPower is one of those sails. Whilst still a primarily 'soft sail' (fully battened Neil Pryde sails didnt arrive until 1984 with the UltraNova range; this HiPower sail was available in different sizes and had an eye to more radical sailing.
