joint looks normal, if there were any watery streaks of rust running down, that would be cause to be concerned. But just a little bottom paint
chipping at the joint isn't a problem.
See if you can get a look at the hull repair from the inside or a receipt from the previous owner for the repair. Usually the yard making the repair will have taken photos of the work
when it was done and as the work
If it's superficial, which is what it looks like in the photo
, The repair kinda looks like someone tried to use a rough polishing wheel
to gring down a deep scratch, then neglected the finishing steps of finer grit and wet sanding
to finish the job properly. Maybe afraid he'd cut to deep through the gelcoat
. But only so much can be seen via photos. Looks like the job wasn' t finished off properly.
