I can't say much about helms cruising boats, but I did own a scow(Y-Flyer) that Jack helms built in lexington south carolina. this boat was about 35 years old when I sold it and it was still winning races. In the early days at helms he built all his own hardware camcleats(advanced for the time) his own blocks some of which were ball bearing, he was even had his own spar sections extruded and tapered them himself. That boat was built from aircraft grade plywood. He definitely payed attention to detail. But my experience tells me that boat deals work on a scale of diminishing return so you might expect to spend a lot on your boat.
Peace and Good luck
