On my last trailer the cradles had foam under the carpets. This is what I should do with my current cradles, but it's a pain removing the carpet. Others have been trailering with throwable life jackets between the boat and the rollers. What is the consensus on reducing shock load's on the boat with the use of foam?

What are you going to padd/carpet the metal hull cradles with? I don't think they exist. We might could fabricate some but big might, they are a tricky part and lend themselves more nicely to fiberglass. I haven't had any issues with the fiberglass cradles if you don't over-tighten the bolts.
