One of the Eastern Washington desert locations we used to travel to for long get aways with our Comp and motor home, is Banks lake, which is about 60 miles long. We stayed in a marina campground in Electric city at the northern end of the lake. This lake is a man made irragation lake with a constant supply of water pumped into it from the Coumbia river. The river water is pumped into the lake very near the marina, and it isn't very warm. The marina has a no wake breakwater. We had to commute the boat 10 miles or so every day to get to warmer water and an empty beach. The Supra cruises ok on a plane, once plaining, you can pull the power way back to keep it there. But I burned a lot of gas doing this. I used much more gas commuting then I ever did playing. I carried two full 2 1/2 gallon gas cans to make sure I could return in the afternoon, and I had to use them several times.
For the last several years we have been vacationing at a very small lake in the North Cascades region, which is only used normally for fishing- nobody skiis theere! We set up the motor home right on the beach, and beach the boat right inn front ogf the motorhome. We ski right out in front of our campsite, it's as if we had the lake to ourselves! It's awsome!
I now use far less gas, and get much more play time.
But cruising is fun. We always make a point of taking an evening cruise. Load up the boat with people (and dogs), and several spare beers or Margaritas, and just cruise the perimeter of the lake in idle for some cool down laps and to say hi to the neighbors.
My local lake does not have a public dock, so we use the boat as the kids swim platform. We do a lot of drifting around in the middle of the lake so the kids can swim.
Many years ago I lived on a good sized lake in western washington that was developed with many homes. I didn't have a boat, but my neighbors did. It was fun to use a tow boat to travel to bbq parties elsewhere on the lake.
