The actual point here is that fiberglass main job in boat construction is not to provide water proofing; this is a side effect you get it as bonus.
The main reason for fiberglass is to provide high structural integrity with relatively lighter weight. That is why there are different types/weight varieties of fabrics out there. As someone who was part owner of a marina, I expect you to know that. So, let's skip the salt water, fresh water and sweet water argument because it is irrelevant.
In your video you said ?Fiber glassing everything together was expensive, so I used marine ply, paint and 3M adhesive?. You knew that glassing was required; you deliberately skipped it because you did not want to pay the cost. You also, most likely knew you will be ?offloading? the boat soon.
Again, in your video you said she had a drinking problem and needed to go
But in your post here you said that after the ?conversion? it got lighter and ran better. So we can conclude that it consumed less gas than before and we can also conclude that the fuel issue was known to you before the ?conversion?
Long story short, per our standards here, your ?conversion? building techniques and craftsmanship were substandard. I personally consider it borderline illegal because there is some guy out there now trusting his/his family safety to this superglue based conversion job not knowing that it is an accident just waiting to happen.
If this boat was able to avoid major safety related accident which I pray to God that it will, this wood will not survive for any significant length of time. The water proof label in marine ply doesn?t describe the wood itself, it describes the glue between plies. Again, as a former owner of a marina, I expect you to know that.
