I'm looking to plan a houseboat trip on Lake Powell and have a few questions. I've heard speeds are generally about 6 mph; does this sound right? And that they generally get 1 mile per gallon? Given that, how far do people reasonably travel? If we wanted to do Clear Creek (canyoneering), it seems like we might want to houseboat to somewhere around Dangling Rope (35 mi, or 27 through Castle Cut from Wahweap) and then take the ski boat the remaining 20 miles to Hole in the Rock. At 6 mph, that seems like about 6 hours, which seems like a reasonable day -- do more experienced boaters think this will work out? If not, what is a reasonable distance for a houseboat to travel in a day?
How much harder is it to drive a houseboat after 3pm but before dark (recommendations generally say to dock by then)?
The information I've seen suggests there aren't usually any good places to put a houseboat in Cathedral Canyon or Mountain Sheep Canyon -- is that true?
How dangerous is it to take a small (16.5') IO up the smaller canyons? How likely is it that I'll smack my outdrive on something while underway?
How difficult is it to find a good houseboat-dockable campsite on a summer weekend?
Any other multi-day Powell boating tips?
