I'm not sure of the strength of my transom tie downs and was thinking of replacing them with those easier to use ratcheting type. My question is the strength of them. The stronger ones are rated for breaking strength of 2,500 lbs with a load strength of 833 lbs. Two of them would equal 1,666 lbs. And my boat is somewhere around 2,500 lbs. I know the boat is also tied at the bow, but what if that gives out? Will the transom ties hold the boat on the trailer?
