action is right, the wind blows alot at Mohave creating CHOP. However, early morning and late eventing are nice to butter like conditions. You can rent a slip at Katherine's Landing which is only about 10 minutes north of Laughlin. They do the slips on a first come first served basis, so if you get up there before the weekend begins you should be ok. Mohave is long and very DEEP.
Personally I'm not familiar with the river there at Laughlin, though you do see alot of PWCs.
