If it works for you, yes.

For me, cruising speed is that speed at which I'm comfortable going long distances. Mine is a semi-displacement hull so my cruising speed is as much above hull speed as I dare to go before my wallet starts complaining, or about 7 to 7.5 knots. It'll ride nice at 10 knots, but I'm throwing a huge wake and throwing away a lot of money in fuel. I could go 5-6 knots and save a little more fuel, but I tend to get impatient.

On my last boat, a light 29' planing hull, I had two cruising speeds; one just a few knots above a stable plane and another just above hull speed, when conditions required it. Both got a reliable 1.4NMPG.
