You all have the right of it when it comes to following seas but Marks parting comment about looking behind you is also key. The temptation can really be to "ride the roller" and not power down the face of a big sea. The risk in this case is that either you will not be going fast enough and the force of the wave, particularly if breaking might slew the boat sideways and broach, or that you might be caught up by the next wave coming along which you hadn't realised was so close behind!
It does take a certain amount of courage to power down a big sea but once you are comfortable with it it can be huge fun .... untl you inevitably get it wrong, stuff the bow into the next wave and get wet! Even then there are degrees of stuffing .... you know you've got it seriously wrong when you look up and its green water above you not white spray!!
Overfalls off points can be more fun still as they tend to come at you from every direction. Often in this case the only thing you can do is pick a relatively comfortable speed and plug through it. Brian you will recall a particularly unpleasant rounding of Lands End over Easter?!
