Hello! This is related to a discussion over at:http://www.boatdesign.net/forums/showthread.php?t=19458

We are trying to figure out some requirements for a "Multi Purpose
Onboard Computer System".

QUESTION1: How HOT does it really get INSIDE the cabin of a Cruising
Boat, in the Tropics? What's the typical you've experienced? What's
the worst-case??

110 in the shade, so humid that plastic rots. Get a laptop that meets
military standard 810F at the least. If you are smart get proper paper
charts and toss the computor.

That or have a genset and climate control (AC) below.



QUESTION2: If you use computer-based charts on a laptop or other
onboard computer, how much Harddrive space do your charts take up??
(Let's say for a passage, or your typical cruising area)?? How large a
hard drive do you feel you need to be "comfortable" for charts and
your other uses??

Go to a digital chart provider and see how big the charts are , and
you will have a better answer. In general the bigger the better, you
may also consider getting an external hard drive and store nothing but
charts on it.
