Lloyds reg. gives 240 ft according to British practice, [length measured from the foreside of the stern at the extreme top to the afterside of the stern post]. Note that at 1:1200, the model LOA of 65mm equates to 266 ft, overall breadth of 15.3mm to 60 ft, hull breadth of 7.6mm to 30ft; the hull breadth aligns with Lloyd's register.
