Rainman Frame AC 240L Torrent, auto leads this shortlist at 12.6 watt-hours per litre: 1.3 hours and 3,532 Wh to make 280 litres. "Best" here means best on the numbers for this combination — the ordering is by what charter boats optimise for, and it does not account for what your dealer can actually service.

How much 240 V AC power does a watermaker need on charter boats?

For 280 litres a day, the leader here draws about 3,532 watt-hours. The spread across this shortlist is wide: compare the Wh/L column rather than the wattage, because a thirstier system that runs for less time can still cost more energy overall.

Why are only 8 systems listed?

Because two filters are applied, not one. 16 systems in our table suit charter boats on output and configuration; 8 of those run on 240 V AC. The remaining 8 are on the full charter boats shortlist and are worth a look if your electrical setup is not fixed.

Why 240 V AC. Needs a generator, shore power or a substantial inverter. In exchange you get the highest output per dollar in the table, which suits a boat that already runs a genset daily. On charter boats: Charter vessels almost always have a generator, so output and reliability dominate. The efficiency premium buys little that you need.
