I just make it a habit to run though a checklist I make prior to boarding. I would never leave the dock without knowing the radio worked properly thats for sure. I know on almost every cat the valves are in the floor boards in the bilge. Not sure if you chartered a cat or not though. Sucks that the guy doing your briefing obviously didn't know or didn't really care. I hope that at least your destinations at each spot during the week was nice for you guys.
