Drop Anchor! (vor Anker gehen)

Normal Sudoku rules apply. Numbers on gray (Anchor) and blue (Ocean) lines are palindromes, where a number X away from one end is also X away from the other end of the line. Numbers on the gray line are a triple palindrome with the center where the lines meet. All sets of three neighbors on the gray line sum to 8 or less. All sets of four neighbors on the gray line sum to 10 or less. Numbers outside the grid are the sum of the numbers on the indicated diagonal. Numbers with a white dot between them are consecutive. Not all possible dots are given.
