You should use the correct equality operator '=~', instead of just `=`, as
explained here:
https://github.com/jeremyevans/sequel/blob/master/doc/dataset_filtering.rdoc#filtering-using-expressions-
So it might just be
DL[:yachts].exclude{(lat =~ 0.0) & (lon =~ 0.0)}.
But check with .sql method to see if that produces the query you want.
Otherwise there are plenty of options for negative conditions:
