Replacement Batteries
I have an Allegro Bay 34, 2006. The house batteries have been replaced once and are dying now. Reading the specs sheet and viewing the 3 holes on top of the batteries tell me I have 2 6 volt batteries...

Steve,
Something is mixed up. If you have 2 batteries with 3 caps each, you have a pair of 6V. If you have two batteries with the connections positive to positive, then you have a pair of 12V. Real 12V deep cycles are very difficult to get (no auto parts or warehouse will have them). If you buy a marine combined service battery, you will be disappointed and it will not last.
If you do very little "boondocking" that is OK, but if you ever overnight without shorepower, you need batteries. If you will overnight unsupported to sleep and sleep only. (No TV few lights, no heat and maybe very little water.) Then you could get by on one 12V as a house bank. If that is not your plan, then spring for a new pair of golf cart batteries.
Please, if you feel you have to go with 2ea 12V (6 cap) batteries. Make Absolutely Certain that the two you finally buy have identcal date codes and the same amount of dust on them. If they are not IDENTICAL, the results will vary with the best case being disappointing.
I did electrical systems on other people's expensive boats for years (before the depression), and I used to have to clean up after several explosions of paralleled 12V batteries a season. It was always a mess, but I liked the money.
