At home i have a MAC.
Bob,
Too bad you went over to the dark side on your boat!
We have been using our PowerBook 3400 on the boat for almost 3 years with no
problems.
I now have two Imacs and intend to use one of them in the pilot house for
navigation. I think the bigger screen will be better. I will have to use a
USB to serial adapter since the Imac has no serial port. We'll see how it
goes. I'll have to fasten it down more securely as well, the laptop just
sits on a rubber place mat and doesn't move.
I have had a desk top Mac on the boat since we bought it. I replaced it with
a G3 last year. No problems except the internal battery died and had to be
replaced. The scanner and printer have worked well in the maritime
invironment as well.
Merry Christmas to you and yours,

After lurking about this list for a couple of months, I thought I'd try to
contribute a little bit. I've been boating, with some gaps, since the early
70s. Progressed from a Hobie 14 to a Cal 20 to an Ericson 29 when I lived
in Hawaii. Since we've moved to Portland, OR, we've had a SeaSport 22, a
SeaSport 27, and now, our "last boat", Voyageur, a Grand Banks 42, single
3208TA with bow thruster. Our cruising area has been, and will probably
remain, the Pacific NW. In 1999, we made it to Glacier Bay, Alaska which
has been a long time dream of ours. We'll be going back in 2000.
This year was our first with a computer on board. I've been into computers
as a hobby since 1978, but didn't think they would stand up to the rigors
of cruising. But, I was finally seduced into trying one by those beautiful
raster charts and the neat software available now. We chose a Dell Inspiron
7000 laptop with a 15" active matrix screen, and we've been delighted with
it. It sits on a R.A.M. mounted stand that we purchased from Captn Jacks
(more about the stand later), and is powered through Voyageur's inverter.
We feed two discrete DGPS signals into the Dell via a A/B switch. The Dell,
in turn, feeds the Raytheon autopilot. The Dell also feeds an OceanPC
daylight visible flat screen display at the upper helm. The software is
controlled by a Logitech cordless trackball which works very well even from
the upper helm. Captn Jacks is the only place I've ever been able to find one.
We bought ChartView Pro, Visual Navigation Suite, and The Capn. All looked
good in their demos, but I didn't want to end up on a 4 month cruise with a
piece of software that I didn't like. They all have their good points. Each
on does something better than the other. But our choice became The Capn
because of the way the Raytheon autopilot uses waypoint numbers. The Ray
needs to see a numerical value in the waypoint place-holder in the NMEA
string. If it doesn't, it won't advance to the next waypoint. The Capn
keeps the waypoint number intact and still allows the waypoint to be named.
The other two overwrite the waypoint field with the waypoint name. With a
good DGPS signal, the performance was incredible, and still very good with
just GPS.
Every evening we would plot the next day's route and print it out on our
little Canon BJC50. In case the computer failed, we would still have
heading and ETA estimates without having to scramble around too much. We
find that if we plan an SOG of 8.7 kts average, our ETAs and ATAs are very
close. We would also print out the next day's tide tables for departure and
destination, and any current tables that would be of value. Am I anal? You
bet! But I'm also a retired airline captain who knows that pre-planning is
about 90% of the battle. This system works really well for us, but is
likely a bit much for most people.
About the laptop stand. It's a lexan tray with a pad of some material that
is very sticky. Not to the touch, but it just seems to hold whatever is
put on it. A very good friend and I had just installed the R.A.M. mount
base and had clamped the tray into place. We put the laptop on the tray to
check for clearance. I had ducked my head under the counter to tweak the
retaining nuts a little tighter when my friend screamed "Holy S**t!". We
had not tightened the clamp enough and the tray had tilted past 45 degrees.
The laptop never moved. The tray comes with straps that we never got around
to putting on. Through sheer stupidity we got caught in a gale in Clarence
Strait north of Ketchikan and were heading into 8-10 foot short period,
very steep seas with lots of spray soaking the upper helm. After about 15
minutes of trying to carry on to our destination, we opted to turn downwind
and head for Meyers Chuck instead. Again, the unrestrained laptop never moved.
