I've read through the posts on this thread and I'm hoping to get solid guidance cuz I'm a bit confused...I'm bringing my AZ registered Yamaha jet boat to Powell in July for a 6 day houseboat trip where we will be on the "Utah side" of the lake...Do I need to adhere to the Utah requirement (training, sticker, and $25 fee) if I'm launching at Wahweap, trailering back at Wahweap and returning to Havasu? I'll never be on Utah highways or roads, only AZ roadways. I'm sorry for the redundancy of the ask...
