OK.... so not much help then... but that really doesn't sound like daysailing so much, which changes things a lot. Nevertheless there were several boats in that search link that may well fit your bill still.
In any event, good luck with your search.. but by the sound of it a cruiser like Cape Dory and others may well suit you best.
