Though the RPM was once thought of as a great boat, those days have fortunately now passed. It is now thought of, how do I say this nicely, as a piece of sh!t. There are many, many better boats out there on the used market. A friend of mine purchased a used Wave Sport EZ for fifty bucks last year, therefore proving that there is no longer any reason for any person to purchase an RPM for more than that price much less purchase one at all. The EZ is a far superior boat with a "modern day hull" and the ability to river run and play all in one package. There are a variety of other, easy to find, used boats out there that are again far superior than the RPM. The disco, EZG, kingpin, fun, S6, or any number of other, "old" boats would be better than the RPM. The X boat would even be a huge step up from getting an RPM. Three words - don't do it. There is only one reason why anyone would tell you that you should get an RPM - and that is to sell theirs to you.
Go to a roll session, try some boats out and stay away from that archaic piece of shiat.
