Question: Could someone sit in the kayak while supported on these stands?
Document: I did not know there was more than one size. This set is just a little short/small, but works great for my sea kayak but I wouldn't be able to use it with my sit-on kayak or canoe. It is light weight, folds easily and fits into a carry bag making it convenient to take to the beach with your boat.
These are well made stands. I use them for supporting my kayak. I was very happy with the purchase. They even came in a nice mesh bag.
They work well in the sand and I plan to set them up in a covered porch to hold the kayak for winter storage. The mesh bag the stands were packed is handy for stuff packed in the stern hatch. Good product.
We bought a 16 foot Ocean Kayak (75 pounds) & these stands are super sturdy & keep it off the ground. (Yes, I'm a neat freak.) Also great when you are washing the kayak down after an afternoon in Biscayne Bay. I love them!! !
Just got these stands today, took them down to the beach to set them up, and they work perfectly. Keeps my 41-pound Necky kayak off the sand but more importantly, I no longer have to give the kayak a shake before moving it to dislodge any snakes hiding under it. While I use a cockpit cover and store the kayak hull up, my beach abuts a wooded area which is home to lots of little critters - including snakes which seem to like kayaks.
Very portable. Fairly sturdy. Very convenient. With stands water. Usable carrying net. I use these for a very light weight boat so they're great for my needs.
this item is lightweight and does exactly what it  is supposed to do. slide easily under each end of kayak. it is well worth the investment.
very sturdy product, would highly recommend to any one with a kayak. makes it easy to work on your kayak for any reason.
they work great.....just wish they were a little taller...easy to use and light enough to carry on the kayak if need be.
Great product, wish I had purchased sooner. Holds my fiberglass kayak very stably and securely. Useful for both storage and maintenance.
Answer: yes
