I'm glad to hear things have improved.
Ok, so "where to next" wise... I may be misreading the situation, but I think the party is still trying to figure out if we have a choice between going there or not. Ie, is there another island nearby, can we buy more time through cleverness/effort by bailing the water? If yes, going to the prison island isn't a good idea.
However, if we can't bail fast enough and there isn't an island close by, then the choice becomes "abandon ship" or "go to the prison island".
