Ship drift speed under the perpendicular wind direction to ships
This means you choose a sinking lure--a jig or swimbait--that will get down quickly enough to allow you to fish it back at your drift speed, which will vary with the wind and current.
a] = 5m/s, this yields a contribution to the drift speed of [v.
In almost calm conditions (wind speed < 3 m/s, during about a half of the duration of the experiments) the realistic wind-induced additional drift speed apparently is a few cm/s.
Drift speed has to be strictly controlled, and rigging has to match speed.
Port gate navigation is dangerous to ships at the time of strong cross-directional winds, because the wind's velocity reaches above 15 m/s and forms a lateral flow (along the coast) and the drift speed of a large vessel can reach up to 3/4 knots, i.
d]--the drift speed of the ship and the evaluation of wind effect can be calculated using the formula:
The drift speed of the ship and the drift angle depend on wind velocity.
