33 ships sunk (200,021 tons) and 4 ships damaged (22,738 tons).

We have a picture of this vessel.
(d.) means the ship was damaged.
[Mine] indicates the vessel was hit by a mine laid by said U-boat.

Note on map. U-66 sank or damaged 37 Allied ships. Our map markers only have 26 labels (A-Z) at this time. This is why some of the markers have no label but otherwise work just fine. The markers are sorted by date, the first 26 successes have labels. This only affects about 20 of the most successful U-boats.

In some cases the exact positions of losses are not known, those are not shown.
In other cases the posititions are too close and the markers overlap, not much we can do about that.
