Box trailer envy!

There was a bit of chatter on the Yachts and Yachting forum about how the guys and girls in the Southern Hemisphere do a nice job of there boat trailers. They seem to do it quite differently to us up here in the North. I've seen quite a few Int Moth box trailers but very few on other classes. Maybe it's time we joined in? This is 'Sacré Bleu!' trailer...
