The 9 Best Boat Ladders

For most boats with a flat swim platform or deck, the Hoffen 7341S is the simplest way back aboard. It bolts down flat, swings over the edge and telescopes into four steps that hang well below the waterline, so a tired swimmer finds a foothold. Polished tubing and grippy vinyl treads hold up to steady use, and a strap keeps it folded while you drive. There are no handrails, so you climb with your hands on the deck.

Ski and bass boats with a platform close to the water don't need a long ladder, and the Amarine Made 3-Step fits them well. Its two deck mounts swing far enough around that the folded ladder can sit away from the hull. Three telescoping steps with black vinyl treads give wet feet a firm grip. The seller calls the steel 316 in one place and 304 in another, so rinse it after every saltwater trip.

Pontoon owners who want something solid to hold should look at the Hoffen 8341SH. Two tall, curved handrails rise above the deck, so you can pull yourself up rather than crawl aboard on your knees. The steps are wider than on a typical swim ladder, which helps with fins or big feet. It flips up and stays put with a bungee strap. Mounting screws can be missing or too short, so plan on buying stainless bolts.

Wide, flat aluminum steps make the Extreme Max 3005.3377 feel more like a staircase than a swim ladder. It pins to a pontoon deck or a dock, and two tall hoop handrails give both hands a grip on the way up. The square tubing is light enough to lift off and carry, and it carries a two-year replacement warranty from the maker. Its weight limit is modest for heavier adults, and bare aluminum can pit in salt water.

The RecPro AL-A suits a dock or a pontoon where people climb out of the water all afternoon. Its quick-release brackets let it snap on for the day and come off for winter storage or trailering. Tall handrails and three broad, ridged aluminum steps give swimmers a steady climb. RecPro doesn't publish a weight limit, which leaves heavier swimmers guessing, and the bare metal can dull and pit near the sea.

Small boats with no swim platform still need a way back in, and the White Water B00365 hooks over the side rail to provide one. Deck brackets hold it steady while it's in use, then it lifts out and stows flat. White Water, a family company in Clearwater, Florida, has made marine hardware since 1982. Its 304 steel suits lakes and rivers but needs rinsing after salt water, and hook-on ladders rarely carry such a high price tag.

A low swim platform needs only a short reach, and the Hoffen 7321S keeps things simple with two telescoping steps. It folds into a small bundle that fits tight decks on ski and bass boats, and a ball latch holds the steps shut. On a boat that sits high in the water, two steps won't reach far enough under the surface for a tired foot, so measure from deck to water before you buy.

If you'd rather not see a ladder on the swim platform at all, the Amarine Made Under-Platform slides into brackets beneath it. Pull it out, and four telescoping steps drop into the water; push it back, and the deck stays clear for lounging and casting. Fitting it means drilling into the underside of the platform, which takes more care than a bolt-on ladder, and the steps are narrow for big feet.

The Mvbouresu RL01 is a backup, not an everyday ladder: braided rope with stiff orange rungs that clips to a cleat or rail with two carabiners. It rolls up small enough to ride along in a kayak, canoe or inflatable dinghy. Like any rope ladder, it swings under the hull when you step on it, so climbing takes real arm strength. Keep it aboard as an emergency way out of the water.
