Thanks Burty!
Must admit I had my doubts, as it looked a little bit weak and feeble for a boat like mine, but I thought it may be a cheaper way out than having my twin-axle one rebuilt and fitted with brakes, new keel rollers, etc..etc.
I did wonder about the '750kg max loading' too. I don't know what my boat weighs, but 750 kees did seem a bit 'on-the-limit'
Still, probably be a bargain for someone.
