Joe, I created templates for them. I worked with Alain who was very particular about getting me a perfect product. Great folks to work with.Tim,
What was that process like? Did you template them, send out the old ones or did they have a catalog of the dimensions for various boats/builders?
Exactly what I did on my boat. Except the leaking ports had started to rot the core so I cut out the rotten parts and have slightly bigger ports now.Custom made will be very expensive.
