Lots of negative replies, If the conditions are right and you take the necessary precautions, I would think it is doable. I don't speak from personal experience but a couple of guys crossed the Atlantic in an 18. If you could average about 10 to 15 knots it should take about 11 or 12 hrs, a long day for sure but depending on wind and current I think its still possible. Having said that I also think its pretty risky with out an escort. Beach cats are for ripping around close to shore and were never intended or designed for long distance sailing, a lot can happen and anything could break. On a bigger boat you have room to carry spare parts as well as lots of emergency equipment or even an inflatable tender. It sounds like a hoot but don't ask me to crew for you.
