twisted trailers,
The best thing you can do is make sure that your trailer was made for your boat or one like it, then be reasonable about the amount of stuff you have in your boat while trailering, the list can go on and on, one big thing would be to have someone who knows what they are looking at inspect the welds on the trailer, recently a relative who is a life long boater, and who does welding sand blasted his trailer and found all of the welds needed re done,I used to travel extensively and have seen lots of boats and trailers sitting side ways across the highway , a loaded boat doing 65 or 70 mph that has a blow out can put some stress on a frame, common sense, hope th is helps , when we went from trailering a 16 ft day sailer to a 23 ft boat I was a nervous wreck, finally it dawned on me, the whole deal is insured, do what u can to make sure you are safe and get on with it, good luck mike b
