As the letter writer pointed out, where in the hell was hand-held GPS as a backup?

You do not need any GPS to navigate between bridge posts - RADAR paints a perfect picture. GPS is good for course work, RADAR and visual is for close work. GPS tells you where the antenna is located, not the rest of the boat. RADAR indicates locations of everything else other than you, in relation to you. Most RADARS sweep 20-40 times per minute, providing that many updates per minute. Along with tracking of other vessels and your track. Maritime law says that if a vessel has RADAR, it must be used when running. Most vesels this size usually have two or three radar sets.
