I sold my 2015 Mastercraft in mid July and took delivery of the '21 in September. The 2015 served me royally but the '21 really shines. I ordered it in August of '20 and my friend used it as a promo boat for the '21 season. Got a great deal and it had 50 hours on it at delivery. Every time we use it, my friends jump in and I never get to drive it! It tracks better, it feels more solid, the driver's seat is heaven, the user friendly screen is terrific! It was worth the wait! In reading earlier posts, I haven't figured out the gas management system....I just lift up the back panel and look/see how much gas is in the tank! Kind of reminds me of Chris Craft days when we kept a yard stick on board and measure by wet marks on the stick! Incidentally, I've owned all 3 major makes over the years and this one is the best!
