KG: As you may remember, Carole and I are kayakers and fish the Colorado river each winter in Arizona. The walkies are great to use in a kayak as they are so small and light. Just clip them to your shirt and your ready. Our kayaks are inflatables so we carry them when on the Pacific ocean sometimes plus the inflatable dinghy. Its great fun to use the kayaks in the bays! Wise to carry the VHF's as well on our nasty ocean when kayaking though.
May be down your way in the fall as we have never been to Catalina. I am sure you have been there many times.
