I'm in the market for a 70-90 ft displacement motor yacht, will be based in US. Some of the boats under consideration are "European" with 50hz electrical system and quite a bit of other system components also made in Europe. Having never been down this road, what exactly am I wadding into? Will having to source European parts / service be an ongoing PIA? Is the on board electric as easy as just using Eurpean appliances and gadgets, or, just a wall converter for small stuff? I'm assuming boats Transformer will take care of dockside power coming in and convert to appropriate frequency. Or alternatively, should I stick with stuff intend to primarily be used in US?
If you have a ASEA power frequency converter, then you only have to accept a longer delivery time and higher costs if you want to replace some equipment… You also have to find out, which country nearby, could supply you with the 220/50hz ‘appliances and gadgets’, to make it more efficient!
Leave your electrical system as is. Several outlets in the states for 50 cycle 220 through 240 volt appliances to hair blow dryers for your wife in Miami, Houston, Bayonne NJ and Chicago . World Import is one such source.
you need to see if your boat is single phase 220V of 3 phase 380V (more easy if you have sigle phase 220V) Hugues
You are asking for some very broad generalizations and the devil is in the details. Every European manufacturer is a little different. Some set up their boats for ease of use and others don't. Some use equipment and parts common and easy to get in the US. Others use those more difficult to procure and often delayed. Your questions are all good questions but just need to be answered specifically for any boat you consider.
Tools are a consideration. Just keep in mind that you won't be able to drive over to Home Depot to pick up whatever power tool you'll need for onboard projects. Something as simple as an extension cord can cause a delay in your work if you don't have what you need aboard. We use lots of dc power tools to overcome this problem.
Let me wade in for a few. Is your boat built for the US market or your importing your own? Is the model your looking for available in the US? Already US ready? Planning on her ever returning to Europe?
The ASEA power frequency converters will accept any input voltage between 180 - 520 volts and any input frequency between 45 - 65 Hz... See: http://energy-solutions.co.uk/products/asea
And it cost lots o money and makes lots o heat (less chillers???). Probably has one heck of a foot print. But if it's going to stay a US based boat (will be based in US, OP#1), why??
Boat's already in states, built for European market. Looking at another similar boat in Europe. Europe is in cruising plan, eventually
So, European boat already here. Already running thru power converters. 220v/50hz appliances already in use? Eventually heading back east? Just trying to get a better picture.
Yes to all of above. For the next few years, I need to be stateside every two weeks so Europe would be tough from a logistics perspective. If European based boat were purchased, would spend a few months cruising before shipping it back stateside.
An Atlas converter should be all you need to install and would convert 60hz to 50hz. Many things will handle 50 or 60hz, so replacing some stuff with U.S. parts is ok, other things will need to be sourced from Europe.
Also consider simple things like exhaust hoses and clamps in metric size. They will most likely need to ordered from Europe as there is limited supply here in the States.
Don't forget televisions and microwave ovens. The Euro 'PAL' was not compatible with the US system pre-digital. The timer for the US 60Hz. micro runs faster? slower? on 50 Hz. <<-------that's what CRS will do to you...
As stated before, this yacht has a converter that converts almost everything (180 - 520 volts and any input frequency between 45 - 65 Hz) to the needs of the yacht equipment...
