I suspect it would cheaper to buy another boat
Fwiw, I sailed a bit of the English (North Sea) and Scottish (western/Irish sea) coasts with friends a few years ago...those waters are NOT calm "ponds!" But if you want to go, there are all kinds of options: WM and others sponsor "rallies" to various destinations, including Bermuda and even trans-Atlantics. A group of boats go as a fleet. They may not necessarily be in sight of each other much, but you're not alone out there. A great way IMO to gain blue water experience.Sailing to the UK isn't that tough...you get a lot of help from the Gulf Stream...it's sailing back that's the hard part. I've known a couple of people who sailed over, stepped their masts and cruised the French, German and Dutch canals for a month, then shipped their boats back on freighters as deck cargo and flew home.
