The WAG SLM-12 mounts to a compatible human swim ladder with at least three steps and standard rungs up to 1.5 inches, with an accessory hook kit available for larger rungs. Twelve steps provide 44 inches of rise for dogs up to the maker's 130 lb limit, and the roughly 18 lb assembly requires no drilling in its standard setup; compatibility is strict, and the unit must be moved or stowed exactly as instructed around human use and boat travel.

The WAG HSM-10 is a ten-step pontoon system that mounts through flush threaded deck inserts and rests adjustable lower legs against the pontoon. It needs 18.5 inches of open deck width, serves decks up to 24 inches above the water, weighs about 23 lb, and carries a 130 lb maker limit while leaving the human swim ladder open; permanent drilling and exact deck geometry make pre-purchase measurement essential.
