Hi, Can anybody confirm if the keel bolts on a Dufour 2800 (1980) sailing boat should be visible from the bilge? Any additional information on this particular model would be greatly appreciated. Got a surveyor to check this boat before buying and although it's in a good condition, I'm still concerned about the keel bolts since they cannot be checked (apparently). I wish to at least confirm that this model was originally built with encapsulated keel bolts. Thanks.
