Hi
Building 21 in Rockland, MA does work for several grady dealers. i had a seam thread pull out. they repaired it quickly and did a great job. i saw a lot of cushion! bolster and enclosure work in process -a lot of grady work. A bit out of your way. if i can help let me know. willing to help.
There's a great custom shop in Nazareth, PA. It's not too far from Bethlehem. Sabatini Coachworks. I've had many things done by him for my own boats, as well as boats through the marina where I work.
