Yep, I'm not an afficionado but from my own alternators, I have an 80amp on the Yanmar, internally regulated, I know that once it is running hot it doesn't put out 80amps, more like 65.
So if you're consuming 260a/hrs in 24 hours, you're looking more lik 4 hours a day charging and that's a problem.
While I agree with the sentiments expressed about the desirability of a genset (I'm busy building one for my boat), I think the solution for you in addition to the battery upgrade is a better alternator. Something like a Leece Neville 180amp unit (my second alt is one of those).
Just as an aside, why do you believe you'll use more power daylight sailing than on anchor? I would have pitched it the other way around. One generally uses more energy when you're parked off.
