We’ve been selling a four step under-deck ladder for years. In recent years customers have informed us that on newer boats with larger pontoons and higher riser brackets, the old four step under-deck ladder didn’t go deep enough into the water.
Ladder is self supporting. Does not need to rest against the lake bottom.
Installing a 5 Step Under-Deck Pontoon Ladder
Installing a 5 step under deck pontoon ladder
To mount you’ll need a 5/16” drill. There are flanges on the front of the pontoon ladder that mount on the front cross member of the pontoon. Then depending on the spacing of the cross members, some are 18” others are 24”, attach the back of the under-deck pontoon ladder to the second or third cross member. Drill the holes and use the stainless steel 5/16” bolts with lock nuts (included) to attach the ladder to the cross member. Try and line up the pontoon ladder so that it is exactly in the center of the pontoon tubes. The ladder is 16” wide by 60” long and will not interfere with many models of center lift pontoon trailers. But, if a boat dealer stores your pontoon boat using a center lift style trailer, you may want to make sure his trailer will fit before purchasing the under-deck pontoon ladder.
Stow Away Pontoon Ladder

Stowed and ready to go.

Our 5 step under-deck pontoon ladder is heavy duty, rated to #300. It pulls out from storage beneath the pontoon deck at an angle. It’s easy to board and stores completely out of the way. Because it pulls out on an angle it’s easy to climb aboard, but individuals with balance issues might find it a problem because there are no hand rails. Because it pulls out at an angle the under-deck pontoon ladder is great at sandbars. The bottom will “dig into” the sand and this makes the under-deck pontoon ladder especially stable. Some customers have told us that because the under-deck pontoon ladder
is so convenient, even their dogs can use it.
