Performance Powerboats To Offer Rear Wind Diffuser For 42- And 36-Foot Catamarans
 

This could be a game-changer for rear bench passengers in Performance Powerboats catamarans, https://www.speedonthewater.com/perf...ot-catamarans/

Kind of shocked the manufactures haven't done something like this already with a GPS or something that says at 45mph this goes up and then comes back down if less than that.
