information on those peculiarly-routed ships and ferries that charge

through the crowded sailing waters of the Bay displayed in real time with

heading, speed, size and possible collision risks assessed.

b). A lesser worry is yachts, but still a real concern in fog. At the moment I

have a pressurized can driving a handheld foghorn. Not dependable nor

systematically used. I would like a Public Address (PA) horn that was

Choices in Upgrading:

1. For the chartplotter at the helm I need a bigger display. Either an iPad, a

daylight visible LCD tied to the navstation computer or a new

chartplotter. I chose the last.

1a). an iPad without large and ugly sun shades which seemed completely

inappropriate in my cockpit, there was no way to read one in full sunlight.

Waterproofing also seems a little funky.

1b). marine LCD: a waterproof daylight readable LCD. No mouse, so

computer and so to the helm display.

1c). MFD: the option of a new multi-function display from Raymarine or

another brand of marine chartplotter. Unlike my laptop, these do nothing

purchased charts (and purchased updates) as opposed to the free,
