I don't have any personal experience with parker boats, but I see a lot of them around. They look sweet and I haven't heard any complaints about them.. I've gone through many boats myself(some good, some bad) and I've found that it pays to look at your options and see any boat before you buy it. If at all possible see if you can test ride. Looks are one thing, but it is very important to see how your new craft will perform in varying sea conditions. I hope that you can learn from some of my mistakes while shopping for your new boat.
