the point at which the step creates the "edge" can not handle the full weight of the boat, if it does, it will hook or deform over time.... no good.

Wasnt there a Teagues on tech answer in a recent Powerboat mag saying that the bottom would return to its original shape once properly supported on a correct stepped trailer?

Nort, I would have them mod your bunks. They can do it pretty easy by attaching some 2x4s to the aft of your bunks, with deep countersunk screws and carpeted of course. My first boat had the boat hanging off the back of the bunks of the trailer, which is not good either.

another reason i like cats.... much easier, although i do make sure that my sponsoons and tunnel are both supported and not just one..... and my sponsons have steps, maybe it isn't easier afterall....

The high and dry let me do this because I did not have to drill holes into there bunk so when I left there bunks were good as new.
Yup that is exactly what needs to be done. Here is the setup I lagged to the 3"x12"x20' bunks for an 42' OL quad step. Not hard to do at all and worth it if you care about your boat.

There are many schools of thought on this subject as we have discussed it with boat builders and "experts in the industry". Everyone here so far has given good advice. If you care about the boat, follow their advice. I have seen boats that when you out a straight edge on them you can see light through the other side. The same boat also has funky water pressure on that motor. Glass returning to its shape once placed on a trailer, never heard one boat builder agree with that statement.
