Don't know if this is of use to any Chrub sailors, but as from Saturday I will have the trailer from Design Source available (the boat is going to Sydney).
It's got a full-length kit box to put all your sails, boom, prod, and gear in, then the boat slides in on top from the back, and there is a fixed mast rack on top for 3 masts (not unlike an 18fter trailer).
It'll be in my garden in Oxford. Cost? A couple of cases of beer... I'd rather see it used than chopped up.
Mobile is 07921 386740.
