詹姆斯·史蒂文斯回答了你关于航海的问题——这个月,随着逆风预报的增加,现在离开还是等待更好的预报?

问题:

Ron,67,has just retired 
and is currently on a 
cruise up the East Coast 
of the UK to Scotland.

The boat he is sailing is 
a 42-year-old fin keel Albin Ballad,a 30ft cruiser racer which Ron has sailed single-handed for most of the trip so far,setting 
off from the South Coast.

He is currently in Lowestoft on a Friday 
in May.The next stage is to Grimsby,100英里以外。

他决定一步一步来做,因为中间港口都没有潮汐通道,除了大雅茅斯,它的游艇停泊有限。

During the passage there are several well-marked shoals and a windfarms.There is a traffic separation scheme,strong tides and 
a precautionary area off the Humber.

Ron doesn't fancy attempting this overnight trip alone so his nephew John has joined him for the weekend.John 
is keen to learn and has sailed a dinghy 
but has no yachting experience.He has arranged to return home on Monday.

The inshore forecast issued at 0100 
on Friday is SW4 increasing and veering NW6 later.Sea state slight becoming moderate then rough.Rain later,然后能见度很好,一开始变得中等。For the following 
24 hours the wind is forecast to be NW6.

Current conditions at dawn on Friday seem ideal.

The skies are clear and there's a moderate southwesterly,which would give a fast beam reach.John only has the weekend free.Ron knows that if he delays he won't have a crew for the long passage.

If it was a short trip Ron would leave immediately while the weather is good,但是,在西北方向100英里处,逆风不断增强,看起来不那么吸引人。你会怎么做?

这似乎是一个理想的一天,如果有一个合适的中间港口,这将是。

Unfortunately,the 
North Norfolk ports are tidal and the coast will turn into a lee shore during the passage.

民谣迎风航行得很好,船长能干。

The crew appears 
to be strong but with no experience there 
is a possibility he may be incapacitated by seasickness when the sea state gets rough.

Once the wind veers and the passage 
is to windward it's going to be hard work with complex navigation.

对于一艘30英尺长的船,机头上的F6正处于舒适巡航的极限,超过24小时的航行时间需要两个小时。

I would advise that it's better therefore 
to wait in Lowestoft for the wind direction 
to improve.

The crew will have to ring through his apologies and arrive home a 
day or two late.
