Thunder Bay Marina - Grand Lake

Located near the back of Duck Creek, only 5 miles outside of Ketchum, Oklahoma, Thunder Bay Marina has all the amenities you need, and so much more.  With Ugly's Grill & Bar laid back dining atmosphere, you can enjoy great food outside on the water, or dine inside to beat the heat where the air is always nice and cool.

For those of you who spend your weekends on the water, Thunder Bay has over 120 cover slips, ranging in sizes from 34' all the way up to 70'.  Need a patio behind your boat for those long evenings with friends and family?  No sweat!  We've got you covered.  Some of our slips already have patios in them, but if there's one you want that doesn't... We'll be happy to build you exactly what you need.

We have on-site shower houses for slip renters, and a full service department on site.  Whether you have a pontoon or a 60' cruiser, Ugly John's Custom Boat's Thunder Bay Service Department is more than capable of handling any problem.  Be it a bad generator impeller, how about a problem with your pontoon outboard, or maybe there is a small scratch in your gel coat from last weekend.  There's not many things we can't handle, and those we can't, we'll find you someone who can.

Come spend the weekend at Ugly John's Custom Boats Thunder Bay, and enjoy a drink or two at Ugly's, where beautiful people come to get UGLY, and we guarantee you'll want to stay!
