The Coast Guard stations along the coast are manned by some of the most dedicated professionals in the service. They can be very helpful in giving the prudent mariner a heads-up as to the current conditions on the bar and the best way to approach the harbor entrance. If you are unable to get information from the Coast Guard or local mariners before approaching, and if there is any doubt about the conditions you might encounter, go back offshore and give yourself some sea room. When it comes to actually crossing a bar, always . . . Most boats have their maximum steering effect at maximum speed.
Swells come in sets.
Watch the rhythm of the oncoming swells. Time your crossing to coincide with a smaller set of waves. 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.
