Acts 27
9 Now when much time had been spent, and sailing was now dangerous because [a]the Fast was already over, Paul advised them, 10 saying, “Men, I perceive that this voyage will end with disaster and much loss, not only of the cargo and ship, but also our lives.” 11 Nevertheless the centurion was more persuaded by the helmsman and the owner of the ship than by the things spoken by Paul. 12 And because the harbor was not suitable to winter in, the majority advised to set sail from there also, if by any means they could reach Phoenix, a harbor of Crete opening toward the southwest and northwest, and winter there.

Now, unless I have no real understanding of what is going on here, it looks like they were NOT trying to go far.
The helmsman (dude who steers the boat) was trying to get them to a different opening on Crete so the ship could “winter” there.

Why was Fair Havens not suitable for winter?
From Gills Exposition:
perhaps it might be an open road or bay, and having nothing to shelter from the boisterous waves, was a place very improper for a ship to be in, in stormy weather; for in open places, as bays and roads, the sea tumbles in very violently in bad weather: this was a haven fit for fair weather only,

Why was sailing dangerous after the Fast?
Elliott’s Commentary:
The sailing season with the Jews was reckoned from the Feast of Pentecost to that of Tabernacles, which fell five days after the Fast. 
…between September 24th and October 1st, when the Etesian winds, which are always of the nature of equinoctial gales, would naturally be most violent.

Look on the map and see how SMALL a distance they wanted to go. Fair Havens to Phoenix was a VERY small hop. This might have been why they did not take Paul’s warning very seriously.  (Also the map misspelled Fair Havens. They have it spelled Heavens. )
