A couple of interesting Superboat 21's. One with an Arneson and one with a Promax 225. Looks like they are both freshwater :clap:

Sell for $22,000. (The value of the motor alone), someone will have to spend considerable more money to come close to the performance capabilities of this rig. This boat works for family or friends. Not only is it good for skiing, tubing or knee boarding, running in rough weather or float partying; it is extremely well respected in acceleration and speed.**Speed is in direct proportion to hydrodynamic knowledge, boating skill sets and testosterone production capabilities.
