Marinebaby 3-4 Step Ladder Under Platform Slide Mount Boat Boarding Ladder, Telescoping Ladder with a Carry Handle and Mounting Screws, Press-Type Spring Latch (4 Steps)

I purchased this to use on my pontoon boat, and I mounted it on the underside of the front and it works excellently! It's very sturdy and even when I left it down once while driving the boat, it did not bend anything although it made my boat on a lot slower until I pulled it back up as one would expect! I highly recommend it. I would just recommend adding some pool handles for people to grab a hold of on your boat above the ladder.

Works great on our pontoon.

Looks sharp, easy to install, fair price. Two issues. First, though steel, it is still somewhat flexible when deployed. Second, since we use it for swimmers getting out of the water, they climb it in bare feet. The rungs are narrower enough that that are rather painful on the feet when climbing. I am using it on a wood dock. If I were doing it again I would build a wood ladder from 2x4 and replace it every few years

Had to modify it for my boat,but not difficult

Functions well.
