Boat US did not require a survey on my J24 only good photos that showed the boat
And older J24 can be a real nightmare of core problems and for example if you look at one that has been frozen all winter things will seem to fine till it thaws out and the core turns back to mush
I think a survey is a good thing if you dont know were the warts are on boat brand X and does give a more objective look at the boat
The one thing i have nevr liked is that the survey person has nothing to lose if he misses something
