I recently removed the fenders on my trailer because the slightest bump in the road created contact with the bottom of my boat causing a small crack which I now need to fix. My boat centered absolutely perfectly on the trailer still sits about 1/4" to 1/2" over the fenders. My problem is my fender brackets are built into my spring supports for the axles and I am having trouble finding replacement fenders that aren't essentially the same thing I removed. The length between brackets are 28.5". Here are some pics for reference. (apologies for the crappy phone pics)
