Great ideas.

First generation, I thinking Arm9, maybe a pandaboards with some LED 
screen mounted together with 2" nylon standoffs. That way, when
I figure out how to add a board that receives and processes signals
from the depth finder, I can use 12 or 14 bit AD to input into
the panda board.

I may also rig a temperature sensor to the boat hull, or via a tether.

What concerns me about openstreetmap, is I had envisioned a system where
the database is downloaded to the operator's embedded system depending
on the anticipated area of local/regional travel, thus not having to
depend on constant/reliable internet access.

Sort of a GPS/nautical navigation system, under the control of the
operator. I'm still learning about openstreetmap so I have moved those
issues (as suggested by our Mike) to that forum, for now.

 From my initial research so far, nothing exist for a marine
environment, so I'll most like roll-it, including some epoxy
coatings and daughter board on the first-gen effort.

My reason for using this list, is to flush out any gentoo-ish
common ground or any hardware suggestions; not an expose
on openstreetmap....

It's liable to be a few months to cmplete this research, but,
I'll post back, or drop you some private email, if you are the
only one interested in what I learn.
