Hi, <br /> My boat uses 2 30 amps AC power cords, I plan on some extended cruising next year. While researching marinas I might visit, I see that some offer only have 50 amp service. When checking catalogs to purchase a Y-adapter, I find that marinco offers two types.<br /> One is a 50amp 125 volt. The other is a 50 amp 125/250 volt. Which is the most common found in marinas? Or do I need to get both?<br />Thanks,<br />Gary
