The worst I have experienced was at work when trying to find a buoy at a water quality sampling site. It was about 200 metres offshore, we had a good bearing, but a hand held compass only, and did not find it. Visibility was less than 25 metres. On our double kayak we have a Silva 75 compass permanently mounted ahead of the rear cockpit. If fog is threatening I set the compass course on the outer ring (I have poor memory), then Joyce can concentrate on the limited view ahead while I concentrate on maintaining the correct course. As there is no wind during these conditions, and no current, it is possible to keep to within plus or minus 2 degrees of the course. It is probably easier to maintain a course with the long stable double in fog than it would be with two singles. We do have a GPS, but it has yet to appear on deck. Now that accuracy has improved, that could happen once I get a suitable waterproof enclosure for it.
