Just thought I'd give everyone some boat towing tips.

)Before you depart, make sure all lug nuts are tightened and that everything is secure on the boat.
)Make sure that your trailer lights are connected, and that the trailer is hitched securely onto the truck's hitch.
)When launching and retrieving the boat, make sure that your truck is in 4WD if so equipped.
)Make sure to remove your transom straps before launching, and put them back on after retrieving.
)When retrieving the boat, make sure the bow is resting all the way up on the bow stop. Another way is to have the driver bring the boat up until the hook for the winch strap reaches the bow stop.
)Then make sure all chains and straps are properly connected.  

Good advice. Other things to keep in mind is the wheels on the trailer take a beating going in and out of water especially salt water so check for rust on your rims and tire degredation. Last thing you want is your rim or tire falling apart on the road. Also repack your wheel bearings often. The water could flush out the wheel bearing grease. Use a good marine grade bearing grease. Check your electrical wiring for the trailer lights once a year for corrosion or cracking. Salt water does wonders on electrical wiring. Keep in mind if you have to replace any electrical wire on a trailer that sees water, there are different grades of wiring and if you do not use the right kind of wire, it won't last a year before you have to redo it. But once you launch your watercraft, "drive it like you stole it"  

That's nice.  

Thanks. I'll need this for when I get a boat.  

Pay particular attention to the tires and wheel bearings. Ever notice how many boat trailers you see on the side of the road when the weather first starts to turn nice?  

It is also a good idea to crisscross the safety chains so that if the trailer comes loose from the hitch ball, the chains form a cradle that will catch the loose trailer tong and keep it form digging into the pavement and flipping over. (Advise from http://www.boats.com/news-reviews/article/tow-how ) Also it a good idea to put the tow vehicle into 4WD (cman) so that strong currents wont pull your boat and your truck into the water especially if you have a heavy boat.  Laugh if you want but it happens so take "cman's" advice he knows a lot.  

good to know
