I have an emergency antenna and wouldn't go anywhere without it. Also have a hand held.

Just to think of the bigger picture, you may want to have a spare antenna somewhere on the boat so that if you are de-masted, you can still communicate. Your range will suffer only a bit if you still can talk well from 20 feet above water (or whatever you can muster). No matter what coax you use, and what antenna you have, you still have a failure point and a spare is the only recovery at sea. Depending on the boat size, you can either mount one, or have one that clamps to a side rail, or whatever - just have a spare. The antenna, no matter which type of coax or even antenna, is more likely to fail before the radio.
