There are several rules of thumb - 10% or 15% of the number of Amp/hours in the battery bank - but it really depends on your personal needs.
A smaller charger will not stress your batteries so they should last longer but it will take much longer to charge them. A bigger charger will take less time but your batteries may not last so long.
If you only require the charger to maintain the batteries to prevent them sulphating while the boat is not being used, a 20amp charger is probably big enough.
If you live on the boat and need to replace the charge more quickly, a 50amp or bigger charger may be more suitable.
Which ever size you choose, make sure it is a multi stage charger as this will be able to monitor your batteries and give them the optimum charge.
