Check part details and conditionIdentify Attwood Boat Ladders: Rope, Platform & Transom Styles
Attwood boarding ladders come in very different configurations. A hanging rope ladder, a swim platform with a built-in telescoping ladder, and a removable transom ladder cannot be substituted simply because their steps look similar. Identify the mounting structure, step arrangement and exact model number before planning a replacement or new installation.
Three Attwood boarding-ladder types
11865-4: Hanging rope ladderFive textured, white 11¾-inch-wide steps suspended by nylon rope. The upper loop attaches to a suitable cleat or railing. It has no handrails and does not use a permanent transom mounting plate.
19536: Swim platform and ladderA white high-density polyethylene swim platform fitted with a two-step telescoping ladder. The ladder slides back under the platform for storage. The unit is intended for appropriate outboard-boat transom installations.
19812: Removable transom ladderA two-step angled aluminum ladder with textured treads, a black powder-coated finish and a quick-release mounting bracket. Its design is aimed at low-freeboard transoms.

What to confirm before choosing a ladder
- Look at the attachment structure. The 11865-4 needs a suitable, strong attachment point for its rope loop. The 19536 is a mounted swim-platform assembly, while the 19812 relies on a specific quick-release transom bracket.
- Check the boat's freeboard and boarding position. The removable 19812 is intended for low-freeboard boarding. Check the height from the water to the mounting area and the ladder's reach when deployed.
- Allow room for storage. The 19536 ladder telescopes under its platform; the 19812 ladder detaches at the bracket. Neither stores like a hanging rope ladder.
- Compare the physical dimensions. The 19536 platform measures approximately 23½ × 11¼ inches (length × width). Its two-step ladder is a separate part of the assembly. The 19812 has an approximately 28 × 13-inch footprint; check the exact mounting diagram and transom clearance.
- Inspect brackets, steps and fasteners. If replacing older hardware, look for corrosion, deformation, broken treads, rope wear or damaged quick-release components. Secure mounting is especially important for boarding from the water.
Load ratings must be model-specific. Attwood specifies a 400 lb capacity for model 19812. Do not apply that number to the rope ladder or swim platform without the separate manufacturer's capacity specification. Use each product's installation and operation instructions, including required backing and mounting fasteners.
Choosing a replacement instead of a new installation
A replacement ladder should match the existing transom's construction and hardware arrangement, not only the step count. For 19536, examine the swim platform, mounting angle, stainless wraparound rail and support rail. For 19812, identify whether the original quick-release bracket remains intact. For 11865-4, confirm the rope and each tread are undamaged and the attachment point is appropriate for the intended use.
