If a sailboat leaves Miami at 5 knots per hour, how fast will it

Impossible to determine without knowing its starting speed.

Starting speed: 0 Knots.

Can you give an instance when this is _not_ the case? Every time
I've started a trip I've experienced a starting speed of roughly
zero knots. give or take.

Er... you seem to have missed the point. The phrase "5 knots per
hour" tells you nothing about speed. It tells you only about
acceleration (that is, the rate at which speed is changing). So if
the boat is cruising by Miami at 10 knots and leaves Miami with an
acceleration of a steady 5 knots per hour, its speed after 1 hour is
15 knots.

Vintage "Dave." I can only guess that you either missed my post on
"acceleration," or intentionally ignored it. The same comment applies to
the original writer's comment regarding "leaving Miami."

Yup, vintage Dave.

most races start when you cross the start line, most crews like to be
underway as they cross it

Interesting, but we're not discussing races. However since you brought it
up, we _could_ consider the very popular races in the Family Islands of the
Bahamas. These start from anchor.

Speaking of other races that start from zero velocity, I like to think back
to my youth as a fairly successful participant in the Le Mans Formula Car
races (falls asleep in a pleasant fantasy)..

Let's see. Tied up at the slip with a current running bow to stern
and the knot meter reads something above zero knots. Does that count?

No. Velocity is measured relative to the coordinate frame affixed to the
terrestrial sphere.

Consider for example a coordinate frame affixed to the vessel. In such a
case the GPS will, regardless of the physical location of the vessel, always
indicate a position where the Greenwich Meridian crosses the Equator.

When you have to back out of the slip! -0.25 knots!

What was the vessel's velocity relative to the geodesic coordinate frame
when it _began_ moving in reverse?

OK, I'm stumped. Isn't the geodesic coordinate frame that house designed by
buckminster fuller in the 60's or 70's?

Depends on the wind of course.... anywhere from 1 knot
to the hull speed.

Don, we're not limited by hull speed in this case.
Why not? Because a hull speed limitation would take
the fun out of the equation.

I can work it out using "c" as hull speed.

It would be more fun if we can go faster than c
and get younger everyday.

What I'd give to be 20 years old and on a boat again! Hull speed shall
therefore be c+!

This is really amusing how this question has taken on a life of its
own!
1. A "knot" is a distance, as in "one nautical mile" in the sense that
I intended it.
2. Newbie Tia - you should purchase Cornell's "World Cruising Routes"
instead of using Google Earth to plan the trip.
3. Tia, have you ever sailed before? Is this a boat you already own, or
were you offered a ride on someone else's boat? We'd all like to know
why you asked such a peculiar question.

Thanks,
Sailor

Hello Everyone,

Has anyone here sailed from Miami, Florida to California ?

Please tell me which is the best route (East or West of Cuba)
and best time of year to do this.

How long does this take in a 40' monohull ?

Should I bring a lot of supplies or is it easy to find them along the way ?

TIA

Wrong! A knot is 47 feet 3 inches.
