BIMARE started to build racing catamarans in 1974 and is still on the market.
Be sure that also the Javelin 16 is a fast and reliable boat.
Besides at EUR 11,560 (carbon mast) or EUR 10,560 (aluminium mast) ready to sail (with hooter) is much cheaper than any F16s.
Therefore if you want to race in a small but growing class go for a F16, if you are looking for fun and plan to race from time to time only Open regattas go for the BIMARE javelin 16.
