Even defeating 75% of the enemy ships (unlikely, usually the other side can row away when things go pear shaped) and losing none of their own, the other side would have a quantity advantage in ships over the whole sea. The Athenians might retain a quality advantage and superiority in force concentration since their enemy at that battle was the only concentrated fleet. This might make things more favorable, but a victory is unlikely but perhaps they can hope to hold off for a stalemate and a settlement (maybe slightly favoring the Peloponnesians) like the 446 BC peace
