The FX One has a maximum load carrying capacity of 350 lbs. This includes the weight of the paddler, any gear they are bringing with them, and any additional passengers that may be aboard. When calculating this weight limit, it is important to keep in mind the stability characteristics of the kayak as well. If you are unsure about the weight of your load, it is always best to err on the side of caution and reduce the amount of items you are bringing with you. This will help ensure a safe and enjoyable experience for all aboard. Have fun out there!
The Hobie FX-One (as referred to in this forum) is not a kayak. It's a single-handed catamaran made in Europe and sold in the US for a brief period.

That being said, it's not really meant as a "family cruiser." It's a high-performance catamaran with a spinnaker - and takes a long time to set up from on the trailer to getting on the water (1+ hour). You're better off with a Getaway or a Hobie 16 for your intended purpose.
But to directly answer your question, the load carrying capacity of the FX-One is 400 lbs / 181 kg.
