I have had not problem fishing two in the front of my 20xrd. The 21's deck is bigger, but I have not had any trouble what so ever fishing 2 in the front. I had a 20xd with a 225 proxs on it. It had a sporty lu with 1.62 gears in it and it would run mid to low 80's with 2 loaded to fish, and get good fuel mileage doing it
