We find we're often trying to use the radio when we're motoring into a harbor. The engine noise below makes it almost impossible to hear. We we end up using a handheld in the cockpit. The communication can be heard (or done) by the helsmsman, so everyone knows what's going on without having to increase stress levels repeating everything while trying to shout above the engine. One worry is dropping a handheld overboard, but a holder and lanyard solve that problem pretty easily. Hand-helds are cheaper than the whiz-bang nav-station units, and likely have less to go wrong. On the other hand, for emergencies, the range is better if you mount the radio in the cabin and pair it with a higher antenna. The question becomes how much range you may need - a portable may offer plenty, depending upon where you are. Of course, after the cabin goes under, you can still be talking on your portable. Sailing is all about options.
