We used to load up the houseboat with all the food and stuff the owner wanted, drive it to what ever beach they wanted to spend time at, anchor it in place, turn on the genny, lights, A/C. refer, ice maker etc, and then return by small shuttle boat. Then, we set up the owner's ski boat so all they had to do was drive out there and have fun. They would return to dock in the ski boat and then we'd return and bring the HB back and unload it. clean it and set it up for dock storage until the next time.
There has been more than one well known public figures who have beat the props off of their outdrives driving their own HB here on LP.
There has been 100 cases of beer put on one HB for a 1 week trip.
Yes the CG Masters License takes a certain amount of days on the water every year and also just to qualify to take the test. The schooling is tough (2 weeks) and it is usually given once a year here in Page.
