We repaired our integral water tank a few months ago, here in Uruguay. This video is a recap of the build project from two years ago, and details of the recent repair. Overall, the integral water tank has been a vast improvement. It is easy to clean and fill. We are happy to make use of the space below our cabin sole that was filled with foam. The 65 gallon water tank makes long term cruising much easier.

I remember your old floor. The new one looks so clean! Wow, big project. You are getting to know your boat quite intimately.
