Over the years we have had many requests for pontoon boat ladders that did not hurt your feet. The problem was that both people and dogs found it very difficult to get out of the water with the standard pontoon boat ladders. Some had to actually swim to shore since they could not get back into the boat. Therefore, we created Aqua-Stairs® Side Mount pontoon boat ladders to meet the needs of both people and pets. In fact, the first side mount ladder was a dog ladder for pontoon boat. The owner of a 140 lb dog requested a pontoon boat ladder that was easy for to get on and off. The side mount pontoon boat ladder is designed for use in the side doorway gates of a pontoon boat. It has floor mounts similar to a keychain and lock used with house doors. This pontoon boat ladder attaches to the floor mounts when in use and detaches from them for storage. Pontoon boat ladders ship with storage brackets to be used if desired. Compared to conventional boat ladders, this pontoon ladder makes it incredibly easy to get out of the water. If your pontoon boat has a gate or door on the rear of the boat, you may want to consider the Aqua-Stairs® Rear Mount Pontoon Ladder. The Aqua-Stairs® Side Mount Pontoon Boat Ladders are the best option when you do not have a rear boarding ladder on your pontoon boat. The opening required for a side mount pontoon ladder is 22″. The standoff legs can be cut off as necessary to adjust to your boat. This ladder ships with to rubber coated J hooks that can be attached to your pontoon railings. This allows you to fold the ladder's legs up and store it on the J hooks when not in use. The ladder supports 250 lbs. This is a high quality aluminum boat ladder.
