Flint,
It's a long haul from Marathon, but Lake Powell has GOT to be one of the best boating venues we have ever experienced. In good wx it is Spectacular, but in bad wx it can be downright scary, and the wind's can be awesome and develop quickly. Watch the weather!
If your boat doesn't have a "KeelGuard," think about having one installed. Many of the nights will be spent with the boat "beached" ashore. You can beach camp with the bow-in, or stern-in, but having your keel protected makes beaching bow-in pretty easy. (But think ahead as to how you'll go ashore off the bow. C-Brats have come up with some very creative ideas in that regard.)
Another item you might want to buy is a length of line (we used about 120' of light ski rope) so you can run diagonal lines to shore. Although you can usually find something to tie your shoreline to - having a couple of screw-in anchors (like some folks use to secure a dog in the yard...) are handy and don't take up much space. You will probably plant your anchor ashore and just use the diagonal lines as stabilizer's.
Having a couple of LED headlamps will permit you to navigate your way back to the boat in the dark while avoiding the maze of docklines run ashore and while carrying two folding chairs (or a glass of wine) to/from the boat.
Be sure to take some kind of folding chair for socializing ashore.
The wx at Lake Powell that time of year will be delightful, and on the warm side ... but unlike Florida, it's DRY. Having some kind of "mister" to spray water will help you stay cooler. A pint size hand sprayer for each person, with an adjustable nozzle works well.
Make sure you have some kind of sun shade for the boat (e.g. a good bimini), and maybe a largish golf or beach umbrella. We have not used the camper canvas during the summer; too warm.
That time of year the lake is Great for swimming, so keep your PFD and pool noodle handy!
Be sure you allow enough time to really 'Explore. A week (or more) before or after the CBGT will be time well spent. It's pretty easy, and relaxing, to spend a month or longer on Lake Powell, it's a BIG lake! The lake has holding-tank and porta-potty dump stations about every 20(?) miles uplake. They are free and very handy. If you have a small freezer onboard (ie. Dometic/WAECO) you can actually keep frozen foodstuff's and make ice which free's you from having to buy ice (which sometimes isn't very convenient).
A pair of "river shoes" that can be worn ashore or in the water will permit you to do some hiking if you're so inclined.
...and naturally - your CAMERA!!!
Gee's, I'm already enthused, and we're not even going this year!
Best,
Casey&Mary
