Nice
Replaced spring loaded ladder on my surf boat. Works better for the kids. This is the second one i have put on a boat. Both work well. Highly reccommended, high quality, very strong.

Great.
I mounted this ladder under the swim platform I built. I feel confident climbing out of the water. I'm 6' 250lbs.

Great Price but Needed Work
It really didn't make sense to put the holes for install in the track, plus they were too small. So I welded an extra plate on and made holes that were much bigger so I could use strong carriage bolts. Also, I wanted to minimize the number of holes I was putting in my Teak swim platform so this way I only had to do 4. I think it came out great but a lot of work to get it there. Also, there is no built-in locking mechanism so they provide a velcro strap which I think is going to be really awkward to do while sitting on the top of the platform. I think I will try and fasten a bungie strap or something easier to lock the ladder when in motion. Overall the price is phenomenal and it is really well made minus the locking mechanism. You just need to plan out your install and know it is not going to be easy or quick.

Works great!
The swim platform on our new boat sits a bit high, which made getting in hard for me (66f) and for my younger grandchildren. This ladder solved the problem. So fantastic! My husband said it was easy to install, even working around the wedge.

Fit perfectly
Installed this on my 2022 Yamaha FSH because the OE ladder was on back order. It fit perfectly. I wish they had a better way to hold the ladder up other than a bungee cord but works ok

The very best quality. These ladders will easily save you $300 from buying from a marine supplier. Quality is there, high end stainless steel parts. 10/10 would recommend.
