After the Swiss boatyard Scheurer (see:
http://scheurer.design.officelive.com/ACatCBlades.aspx)

also BIMARE started to work on curved foils.
In a couple of months a version of the new V1 fitted with double daggerboard cases (the helsman will have the opportunity to choose if to sail with curved or traditional foil at the start of each race) will be on sale.
Unfortunately the option will cost EUR 1,000.
