Cubozoans are the fastes jellyfishes.
It depends on how fast that small sailboat is traveling. The wind also varies in intensity greatly, so there really isn't an average wind speed to even try to calculate how long it would take one sailboat to sail one mile.
Depends. Size is not the predominant factor when determining speed for a sailboat. Depends on the wind condidtions
Four times the speed of the wind is the fastest so far.
5mph
There is no one specific rate. Rate of acceleration measures how fast something gets to a certain speed. In boats this could be a huge variance depending on whether its a small sailboat, a huge ocean liner, or a fast speed boat.
can go bout 5mph-10mph
5mph or less
It depends on many factors. The hull shape, how the sails are rigged, how much sail area you have, the ability of the crew, the wind speed, the tide.
Usually not. It'll be fast at the start, but a small crank will limit top speed unless you can turn the pedals really fast.
High Speed Cruise: 446 knots
If you are really fast then your power is great if you are slow then your power is small
