That's kind of cool. I'd buy that for sure if I needed to replace my ladder, but I don't think I'd ditch a working ladder for it.

Here is the link. $1393.38 for everything needed for two seats. I would think you would want some sort of backer inside the hull though since other boat models were not engineered to attach these. With that said, you would probably need longer bolts (Part #39) if you were to put the backer plate...... Cool concept, but the juice is not worth the squeeze......

I agree. I like to sit on the square throwable in the water at the transom.

If you shop around I’m sure you could find a little better prices. I payed less than $500 for everything (one seat not two)

Did you add any kind of backing plate inside?
Was it hard to get to the inside part to connect the nuts?

It’s not impossible but not easy. After removing the tray at the cleanout ports it’s a far reach to get to the aft bolts. I used a 1/4 aluminum backing plate and drilled the holes slightly smaller. I threaded the bolts through the backing plates so I didn’t have to hold the actual bolt as I was finding the hole location. There’s no way I could have reached the aft bolts

There’s a little more info and pictures in this thread
