see what you did donny? give'd jeffies hiss chance ta told uses jest how
smarts he bees. but dens the dods says sumpin stew ped likes:

Of course, in practice one usually doesn't need to know the
strength of a current to 1%, but it isn't impossible to calculate it.

in fact, soooooo stupid jeffies doesn't even know how stupid.

geesh that boy is dumb. 1% of a guessed-at current of 5 (yup, five!) knot
current is a **calculated** guessed-at 0.05 knots. great precision, but no
accuracy. It started with a guess, so it can't get better.

but it does show that jeffies is one bight boy. no wonder he carries a 200
year old copy of Bowditch and "other navigation texts" to motor from one
anchorage to the next.

However, the tables, along with trig tables, have been published in Bowditch
and
other navigation texts for over 200 years. They certainly ARE part of the
traditional navigator's toolbox.
