We take on building a tiny house/overnighter structure on a recycled junk yard 25' Bentley pontoon boat! There were various struggles to get a good set of pontoons and under-deck structure. One had water in the tubes that could be removed, possibly in a chamber, and then another boat, the Sylvin had a cracked pontoon which the welder did not want to guarantee, so ended up with the Bentley you saw in the field. I am going to try to upload every other Thursday till it's finished!! Stay tuned!
