I had him build me a 14' scooter from the old Majek mould a couple of years ago. He did a pretty good job, took quite a bit longer than he estimated. I was happy with it in the end. We did a lot of custom changes like cutting the console down so it was not so wide, and I know that caused some of the delay. We also mounted the hydraulic jack plate motor in the console, he had new hoses made for me.
I even had a small problem with a crack. Probably was my fault, but he took care of it.
I would recomend him for a custom boat, just be prepared to be patient on timing. Also make sure your write everything down. It helped us get things right, and fix some small things that weren't.
