Depends on the boat, your choice of sail, the sea condition and how the boat is rigged. I'm going to say that, on a broad reach, with nearly calm following seas and a 150% decksweeper, clean fiberglass hull, sloop-rigged, I get I could get that done in 50 hours give or take a lot. Beating into that in a 35,000lb Wetsnail [sic] will take longer (and longer). Broad reachings on a 60' light air sled with a big chute up would take considerably less. Note that this isn't really simple algebra at all. Even headed dead downwind in a constant 6kt breeze, I'm not going to actually make 6kt SOG. I can think of 20 mitigating factors off the top of my head.
Well, a knot is 1 nautical mile per hour.
20 hours ! 1 knot is 1 nautical mile per hour.
4.7 days at 19.5 knots
The knot is a unit of speed equal to one nautical mile per hour. Therefore moving at 3 knots it would take 350/3 = 116.6666666666667 hours to go 350 nautical miles.
It takes (58)/(your speed in knots) hours.
It depends on how how fast the wind is
It takes a bit over 3 hours to sail 19 miles at 6 knots
A knot is a nautical mile per hour. Thus it will take 10 hours at 10 knots.
about 7 days in a favorable wind, since the ship would sail at 4-6 knots
1/20 hour = 3 minutes
The distance is 6665 nautical miles. 27.8 days at sea, speed of 10 knots
To calculate the time it takes to sail 6,000 miles at a speed of 10 knots, you can use the formula: time = distance ÷ speed. At 10 knots, which is equivalent to 10 nautical miles per hour, it would take 600 hours to cover 6,000 miles. This translates to 25 days if sailing continuously without breaks.
