I have two cats and two trailers right now, and I want to swap the trailers as the one which came with my Nacra is more recent and lighter to move around.

In order to do so I have to install new hull cradles on the cross bars and so on. But I was looking at the A class trailers on the parking lot at Grafham this week-end and they do not use hull cradles at all, they use beam supports (because I assume the hulls of an A class are too thin and light to be strapped down on cradles). Somewhat similar to the system on this roof rack.

Anybody tried such a system on a F16 trailer? pro? cons?
