Hello Edwin. The Curt Class 1 Hitch # C11258 for the 2015 Chevy Sonic is rated for towing up to 2,000 lbs. Based on what I can see online a SeaDoo RXP 300 weighs about 780 lbs. I imagine the corresponding trailer is fairly light as well. So, as long as the weight of the jetski and the trailer is less than 2,000 lbs you can absolutely pull a trailer with this hitch. view full answer...
