Re: 87 Renken?
There is a reason they call them sinkin Renkens. Every one I have dealt with although they ride nice had stringer and soft floor issues. These were all boats with Gelcoat floors. I just don't think they sealed them up real good.
I just replaced the floor in a 28' WA for a friend. I would not feel great about going out on a 20 year old boat that was built poorly when it was new.
