Avoid quartering across the bar. Present your stern as square to the swells as possible. Work hard at the helm to maintain this attitude as it is your best chance of avoiding a broach. Most bars are short, have narrow entrances and other traffic. If conditions are such that you are even thinking that a drogue would help, you belong offshore with plenty of sea room.
Visibility is crucial.
It is both safer and faster. Under the right conditions, crossing a bar is no more difficult than entering any harbor. Under the wrong conditions, it can be the most foolish and deadly decision a mariner can make. If you are offshore and conditions have already gone bad, stay at sea and take your lumps.
