This helps us understand the sort of refrigeration you will need.
For boats cruising in hot climates like the Med or the Tropics we recommend you select water cooling which is the most efficient system possible because water dissipates heat far better than air (some 20x more effective) so will dramatically reduce your power consumption.
Boats cruising in Northern European waters will normally have lower ambient temperatures so air condensing sets are more than adequate, although water cooling will still be more efficient it is less critical.
If you are starting in Northern waters and heading South then select Med
