Once my Sea Ray Sundancer 380 is shipped to Europe, what will I need so that I can use the 230-volt A.C. shore power there? G. S., via Electronics forum
A better solution is to do as large, far-voyaging yachts do: permanently install a real marine isolation transformer designed to handle continuous loads. Companies like Mastervolt (www.mastervolt.com) and Charles Industries (www.charlesindustries.com) offer models appropriate for your size boat. These units can typically be set up for whatever voltage and frequency is available, and it’s worth noting that an isolation transformer, even when it’s not actually changing voltages or frequencies, reduces shock risk (hence the British construction regulations) and also the chances of galvanic damage. Some careful boaters consider one a necessary piece of equipment, regardless of their travel plans. Note also that simply converting your existing A.C. system to work with European power standards may not do the whole trick. You may want to use European appliances onboard—a regular TV, for instance, if you don’t have satellite, since broadcast standards are different, too. That means you’ll either have to install a 230-volt circuit in the boat or use a small portable transformer to turn the 110 back into 230! Certainly it would be simpler if we could all go to global standards, but which countries are going to give up their own?
