You'll be able to charge up on the hook/mooring with your engine. If you aren't able to be there regularly I suspect you could last easily up to 2 months without a charge. The bilge pump would be the single most likely load. If it drains your battery you probably have bigger problems to worry about.
Assuming that you have lead acid batteries and that they amount to a bank of 400 Ah then the highest charge current you could use is 100 amps. Assuming that you didn't discharge greater than 50% then it would take you absolutely no less than 2 hours to get to full charge. This doesn't even include the absorption phase of charging. There is a reasonable likelihood that you have an alternator and charge controller on your boat that nears 100 amps. If not, then your $399 would be better spent on an upgrade. IMO. So that a run away bilge pump doesn't kill your batteries between visits, you might want to consider a "priority start" or ensure that you have a dedicated starting battery. The priority start is a device that separates your small electrical loads once a low battery voltage condition is reached. The low resistance of the starter reconnects the battery during an attempted engine start. These devices were developed to prevent killing your car battery by leaving the headlights on.
