Trust your tracking: Stop watching the boat in your mirrors so often on the highway. Your boat will go exactly where your vehicle goes.
Pull it over in 15: Pull off the road and feel the wheel bearings and hubs 15 minutes into your trip to make sure they're not warming up.
Don't tow in overdrive: Even from the house to the ramp, towing in overdrive is bad for the vehicle and could void your auto warranty.
Batten down your hatches: Double check latches on boat hatches to make sure they're holding correctly. On a runabout, make sure the center windshield is closed and locked in place.
Check your wheel grease: Make sure the bearings are greased, especially if you've been in and out of the water several times. A little condensation is bound to find its way in, and your bearings could rust and seize up on you.
Sit out that storm: "If the weather has your knuckles getting white on the steering wheel, pull over to the side of the road," says Thompson, "The life you save may be mine."
