1. Avoid bumpy roads
   Check the tire pressure before you leave
2. Change your tires every 6 months
   None of the above

Since a flat tire can lead to a fire, nothing beats actually hunkering down and manually checking the pressure of each tire with a pressure gauge to verify their soundness. This should be done before every trip. <a href= "http://auto.howstuffworks.com/auto-parts/towing/vehicle-towing/boat/boat-towing-safety.htm"> How Boat Towing Safety Works</a>

1. Corrosion
   Dirt and/or gravel
2. Moisture
   None of the above

One place to start is the electrical system. Have someone stand behind the boat trailer and verify that all the signals are working. Brake lights, blinkers, running lights and brakes should all be checked -- along with the connector between the tow vehicle and the trailer where the wiring passes. Corrosion can be a problem, and the wiring can chafe and short-circuit if not routed in properly. <a href="http://auto.howstuffworks.com/auto-parts/towing/vehicle-towing/boat/boat-towing-safety.htm">How Boat Towing Safety Works</a>

Don't underestimate the importance of having your hitch system checked out by a professional. He or she might recommend additional equipment like a weight distribution system or a sway control device, and he or she can tell you how much of a load the system can handle and make sure it's in good working order. <a href="http://auto.howstuffworks.com/auto-parts/towing/vehicle-towing/boat/boat-towing-safety.htm" />How Boat Towing Safety Works</a>

1. Engine
   Cooling system
2. Brakes
   All of the above

There are a number of components of the tow vehicle that'll be under considerably increased strain while you're towing, and this needs to be taken into account. Make sure the tow vehicle's engine, cooling system, brakes, suspension, tires, transmission and other components are all up to the job. <a href="http://auto.howstuffworks.com/auto-parts/towing/vehicle-towing/boat/boat-towing-safety.htm">How Boat Towing Safety Works</a>

1. Add several hundred pounds to that number to account for additional gear
   Nothing. That number is absolute
2. Divide it by your vehicles towing capacity
   None of the above.

Determine whether the tow vehicle can handle the weight of the boat by getting the dry weight of the boat from the owner's manual. Then, slap on another several hundred pounds for all the fuel and gear you'll probably be hauling along, too. <a href="http://auto.howstuffworks.com/auto-parts/towing/vehicle-towing/boat/boat-towing-safety.htm">How Boat Towing Safety Works</a>
