It's mad how much faster catamarans can be than monohulls. When I was a student me and some friends got together and bought a used Dart 16 with the spinnaker kit, it was the fastest thing there by a huge margin (albiet because most of the boats were the usual student fare, Fireflies, Laser 2s, GP14s). We played a fun game called 'cat and mouse' which was basically British bulldog but on dinghies, the club boats had to avoid getting caught by the much faster catamaran but it was a fair game because the cat was hopeless upwind and the slower club boats could point far further and escape.

The most fun I ever had on that boat was at Bala Lake in north Wales, honestly one of the most underrated dinghy sailing places on the planet in my opinion.
