The moulds acquired are the 500 series and the 565 bowrider, bass boat and cuddy cabin plus the centre console.
The 590 series bowrider and walkaround, and the very popular 640 centre console and cuddy cabin are also among the range.
They will be manufactured alongside the Lewis range of ski and wakeboard boats, and marketed under the Lewis brand.
Lewis Boats director Steve Parker said: "I have always had great admiration and respect for the Southern Star moulds, and, having owned a centre console model myself, I am personally familiar with the performance of these boats.
"I am excited about this new venture for Lewis and I am looking forward to having these models compliment my existing range," he said.
