I think that if trailer sailers had all been mainsail driven and not fashioned like mini IOR racers they still would be popular.
timpenny 670 , farr 750 , magnum 8.5 , spider 28. , Nolex 25 , nolex 30 . There are more those are just the ones within a 10 radius
I had a Status 19 that was mainsail driven and that and the ones you mentioned are still selling well. The 50 other brands from the 1970's that looked like scaled down IOR racers not so much.
The magnum is a difficult boat to sail . Not user friendly at all ! The Farr b30 is also a shocker ....... Many mast head TS way better than those two .
Great to see a new locally designed and built trailer sailer doing well............
As per Afloat November the Cygnet 20 is now up to build #16 with order book full till Oct2020.

It looks to be very well thought out all round.
