The past few days have been interesting, informative, and a little intimidating. I can certainly understand the need to have a metal hulled boat fully surveyed. ( maybe any boat for that matter). For an educational exercise I looked at a few Roamers in my neck of the woods. It amazed me what a nice coat of bottom paint can hide. I am understanding more and more about the rust on the inside of the hull. While a person can do some rust removal on the inside of the hull, getting access to some of those areas can be a real challenge. When ever I would chat with some of the local boaters and mentioned that I was looking at an older Roamer, I would always get a riased eyebrow, and a mild warning, " ya know they rust from the inside out". I was told that you just can't get a "gas axe" out and cut away hull material. The oriiginal coatings on the inside of the hull might get a little excited when that type heat is involved.
I have located a few Marine Surveyors in the Saugatuck Michigan area. That Audio testing would be critical. I haven't been scared off yet. But I will move ahead with a little more caution than I would have before I began reading this forum. The search continues.....b
