Our first impression of the 210 was that this model offered well thought-out space, great looks, and cool technology features. Then when we found out this model is offered with a single supercharged 1.5 L engine OR twin normally-aspirated 1.5 L engines, we had to take a closer look. In a time when boaters have been looking for better all-around family sport boats, the team at Sea-Doo has been responding with models like the Challenger series. This 21’ model sells for under $33,000.
