I've solved all the clues except for 7d - For yachtsmen, this instrument came adrift? (5).
I've got the original and modified 1d and the messages from the extra words, but I haven't put anything in the grid yet. With that in mind, is it worthwhile trying to enter the answers to the across clues, or should I just not bother with all that and go straight to following the instruction from the across clues?
