One can forget about getting un-marked and old equipment 'certified'.
If the boat itself is delivered from the yard/builder with CE compliance certificate and shore power installed, it is the responsibility of the yard/boat builder.
The only 'legal' way around, is by using a heavy CE marked battery charger and then connect the 110-volt system in the boat via an inverter from the battery pack!
You may read the 'basic' here:
CE mark - Wikipedia, the free encyclopedia
One thing some people are not aware of is that non-CE marked products that requires CE marking are forbidden to import and sell within EU.
If you for some reason take your boat to EU and want/need to sell and go back home, it is in general by law illegal!!
However you may get around that too if registered as 'commercial vessel'. It must however in that case enter EU as commercial vessel, and not be registered after having cleared in as 'private pleasure craft'.
If already in Europe, that means in general you may have to take a trip to:
Russia, Libya, Tunis, Egypt and re-register!
There are other countries that are not members of EU, but by agreements bond to follow the regulations.
