A long range cruiser has different interests; his need for a chartplotter
in the open ocean can be met with far more economical solutions, consuming less precious amperage but still being capable of driving an autopilot
and providing alarms.
441 uses 15 watts max at 13.8 volts, and provided N2K connectivity, AIS
plotting, and XM weather
in the US. It takes very little room at the helm
but can be easily read in all weather
conditions including direct sunlight. It can't display radar
So I suggest that a navigation
solution for a long distance cruiser with minimal demands for continuous power could include a small chartplotter
, and an on-demand computer system.
planning can be done on the PC and transferred to the GPS
with SD cards. PC and chartplotter can share AIS
sources without resorting to a multiplexor, and both can drive an autopilot
or trim some vane steerers.
With a rather expensive antenna
, the 440 can display weather.
