Sonar Eclipse

Fill the grid with the digits 0-8 so that digits don't repeat in any row, column or 3x3 box.

This section of ocean contains black ships and white ships. Visibility is low, but entering correct digits might clear fog somewhere in the grid. No guessing is necessary.

A black ship lies on every orthogonal edge between two cells with a 1:2 ratio. A white ship lies on every orthogonal edge between two cells with consecutive digits.

(Note: it is possible for two different coloured ships to lie on the same orthogonal edge)

A few ships are shown (beneath the fog), but most aren't, and must be located by using sonar.

A sonar cell is a circle whose 'search radius' includes itself and all neighbouring cells (orthogonally and diagonally.) The digit in a sonar cell indicates how many ships matching the colour of its circle lie FULLY within its search radius.

Not all possible sonar cells are shown. No two sonar cells of the same colour contain the same digit.
