No matter what your application, you'll find the Sea Ray 370 to be a fast boat, even with the tower. I found 36 mph running at 2,550 rpm to be a very comfortable cruising speed. If you want longer range, 2,100 rpm translates into a more efficient 27.5 mph. And few inboard boats will keep up with you and your 3116 Cat diesels on your way back from the fishing grounds at the 370's top speed of 39 mph. The only downside of this fine turn of speed is the turbo whistle, which I found fairly pronounced at higher speeds.
