I agree 100%. I would never give up the paper charts and always will
consider them the primary navigation tool. It's a question of
constantly updating from GPS fixes or from time, distance, and cross
bearings.

============================

Roger, there seems to be a misconception evident on this thread, not
necessarily yours, that using a GPS means giving up charts. Far from
it in my experience. The paper charts may be safely stored below for
emergencies but I always have at least one set, frequently two sets,
of electronic charts at my disposal, both fed from separate GPS
sources, and both maintaining a running track.. My Maptech BSB format
charts on the laptop look exactly the same as the paper charts and are
used the same way also, just more convenient, and with some electronic
bells and whistles thrown in. Who has the time to maintain a manual
DR track when running at any kind of speed in congested waters?

My experience has been that waters are usually only congested when the
navigation and visibility are easy enough that you don't need to keep
a running plot on paper. I'm sure there are places that this is isn't
true and I would have the best GPS I could afford if I spent much time
in them. A larger vessel constrained by draft in traffic that was
ranging over a larger area with few fixed navigation aids would be a
good example.

Piloting without GPS now comes into the realm of a sport in itself
(sort of like making a vessel go somewhere without an engine). The
mountain climbing analogy holds. You do it in specific places for the
experience and satisfaction of achieving it. You wouldn't try to get
to a job interview in Manhattan that way.

Speed is also a factor. I spent a couple months trying to decide
whether to buy a power boat or a sail boat. I always envisioned the
power boat with a big GPS, radar, and all the stuff I'm used to from
these boats I associate with professionally:

I'm used to congested waters. I used to go out on a busy Sunday
afternoon in a Soling on Boston harbor with someone (usually a girl)
who had never been in a boat before, set the spinnaker, and sail
around. I used to think I was a hot ****. Now I'm old enough to know
that I was just arrogant. I never had a problem with the spinnaker
though and have only returned to the mooring with a hole in the boat
once in my life (on the port side, fortunately). That was the day I
met my wife.

Was your future wife the one that made the hole in the Soling? :-)

No, but talking to her may have made me slightly less attentive

Actually, I saw the other guy but Boston Harbor used to be (and
probably still is) full of hotshots who like to skim your transom on
port tack like they were in a race. By the time I realized he wasn't
going to do this, it was too late to take evasive action. The
burdened boat is supposed to maintain a predictable course anyway
although there is a fine line between doing this and failing to take
action to avoid a collision. I fault myself for not verifying that I
saw a pair of eyes, or at least a head, and learned.

His story was that he was in a channel and I was crossing it so he had
the right of way. It was arguably a channel because the area is
heavily buoyed and ones in the area were arranged to guide larger
boats to the gaps between a couple of islands but it was not charted
as such and we each would have had 20 feet of water under our keels
anywhere within half a mile.

What kind of boat did she port tack you with?

Nice video of the Tioga hauling a*s up Vineyard Sound past West Chop.
I just installed the same Furuno integrated charting/plotting/sounding
package on my trawler and am very impressed with it. What kind of
power is in the Tioga?

She's only doing 17 knots in the video but did 21 on trials. She'll
go 18 knots all day long with a 10,000 payload.
