All Lifeboat garages have a ramp leading to the sea that helps it reach the sea at any tide. They are all built so that the tide level will never affect a launch.

This question is unanswerable since there are many sea-raids in history and there is no way to know which one is being asked about.

There are various reasons

1) Close to the equator which adds boost to rocket to launch.

2) very good geographical corridor to launch satellite(launch corridor).

3)It is towards east side ,earth rotation give advantageous.

4)Good transportation facililty

5)Near to Sea ,in case of failure it will fall into sea.

5) uninhibited land.

6) Atmospheric reasons ,weather conditions should not be problem to launch vehicles,most of the days it should be clear .
