Not a bad job though with respect to the build of the trailer...
My only worry would be the thickness of the main longitudinals rails...are they 3mm thick? As they are not doubled or built using a 'ladder' design they have to be pretty strong. At the moment, the weight of Jeepster and the wobble rollers is being transfered down to the rails at a nearly equidistant point either side of the axle meaning that the rail is resisting being 'bent' over the axle.
You say the boat weighs approx 450kgs meaning that with the weight of the rollers/bars +fuel+gear on board, (not counting an engine) etc... you can easily be in the region of 600kgs (or 150kgs acting down either side of the axle on both sides).
Its just my opinion but i would consider Either reinforcing the side rails or adding a keel roller or two as close as possible to the axle to alleviate the weight on the sides.
Maybe an optical illusion but in the pictures it looks like the side rails are already slightly bent as they are loaded?...might just be my poor eyesight though
