So, just to try and clarify...

If you want to be miserly with fuel, you need to keep your speed at, or below, "hull speed." For a hull speed of 7 kts you need a boat with a length-waterline of a little over 27'. For a hull speed of 10 kts you need a boat with a length-waterline of more than 55'. Obviously a big, big difference.

If you are willing to travel around 7-8 kts most of the time, that should be no problem in a boat the size you are considering. For the occasional burst to 10 kts or above, just be aware that your fuel consumption is going to go up exponentially.
