Hi Nicola,
14D: The answer is a spread and the word is made up from a naval soldier around a scrap of cloth backwards. As it's a down clue, "up" is used to mean backwards. Alternative clue:
Spread arm a reign about
22A: The answer is a fish (or a boat) consisting of a word for dehydrated around a single letter for "old" (sometimes clued as "zero" or "duck"). Alternative clue:
Unknown perch backed fish
24A: The whole word means to squeeze out and sounds like (hear) a sound. Alternative clue:
I escaped from wiring the squeeze
Hope those help.
