Planning a route to meet arrival deadlines, avoiding synchronous rolling, and not losing cargo overboard is both an art and a skill. There exist a plethora of computer routing programs which can assist a mariner in route planning and then route deviation, but to use these programs effectively a mariner must understand what factors are being used by the software to develop a proposed route.

And how current and accurate is that information. A correct route for one vessel is not necessarily the correct route for another vessel sailing between the same departure and arrival ports. A US Navy destroyer and a car carrier would likely use different routes when crossing the Pacific Ocean during winter months.

A simple and effective method to determine a route prior to departure is to lay out four 4 routes: Great Circle, Modified Great Circle, Rhumb Line, and Bucket route. Note the height contour which denotes the southern extent of storm force surface winds. Measure nm north of the height contour which is always the darkest height contour shown on the mb chart. Note where the four routes you plotted fall in relation to the area bounded by the height contour and the nm line drawn parallel and to the north of the contour.

I think of vessel routing as analogous to driving down a busy highway where you adjust your lane and speed to keep heading in the desired destination. Computer routing programs are often not as sophisticated or capable as a mariner who examines mb, surface, wind wave, and wave period charts.

While sailing as Master on slow moving US Army LCUs and LSVs 10 knots was our planning speed I would examine Ocean Prediction Center charts several times a day, and adjust tweak our intended track to maintain wind and seas abaft the beam, and minimize rolling. Yes, there were times where weather systems developed quickly and we would endure some short term discomfort. Have a news tip? Let us know.
