The third version of the SCAMPI was built by a number of firms around the world. (In Japan as the YAMAHA-30). It continued its winning ways by placing 1 2 3, in the Int. Half Ton Cup of 1971, held in England. It is thought that nearly 200 of the MKIII version were built, and many more of later versions, making it one of the most popular boats of this type ever.
