In voyage planning, is it possible to prepare for “blind” pilotage technique in restricted visibility ?

Sometimes, since reduced visibility can be seasonal in some places and an increased likelihood of its occurrence can be predicted.

When voyage planning, is there any advantage to have a waypoint, or wheel-over position, when a significant headland (or visible navigational mark) is abeam?

Yes, it makes it easier to know that the vessel has arrived at that position.

When preparing for a voyage plan, how would you improve the vessel’s efficiency when selecting a great circle route between two points?

by reducing the overall steaming distance between departure and arrival points

When executing a Voyage Plan and the vessel has been forced off the planned route by crossing traffic, should the Officer of the Watch (OOW) bring the vessel back to the planned route as quickly as possible?

No, vessel should be brought back to the planned course in convenient manner, without radical alterations.

In the application of a voyage plan, the use of “parallel index” techniques, is it correct to reduce the interval of taking positions?

No, the frequency of position fixing should be maintained.

When executing a voyage plan, how often should the position of the ship be obtained and marked on the chart?

it depends on the location and how close the ship is to danger
