ARRIS Fast RC Jet Boat with Self-Righting, 2 Batteries High Speed Water Jet Pump, Weedless Safe Design for Pool Lakes Shallow Water, 2.4Ghz Waterproof Sport Jet Boat for Adults Gifts

Just go on amazon and get one of those $20-30 almost hoby grade boats that can do 20. That should be great for a starter boat and small boddies of water. A jet would be much better for a creek so check amazon for those (like this). The biggest thing is read the reviews to get an idea of what it will actually do.
