I'm not asking because I am looking at a boat. I'm asking because all I read here is Get A Survey and I keep thinking there must be a crowd that like me thinks there are other cases. I suppose if someone is asking questions here they are better off getting a survey. There is definitely an emotional side no matter what. A few months in the bilge always cures that quick.
The issue of a good surveyor is as important as "get a survey". For every boat I have owned I have seen old surveys done by previous owners and wondered. They are often terrible, brief and stating the obvious.
All this being said I have to get a survey soon, for insurance purposes. I guess there isn't much point in not getting one!
