Boat or recreational vehicle ladder apparatus

A boat ladder apparatus comprising:

• an upper tread including a foot-grippable pattern thereon;
• a first elongated receptacle extending from a bottom of the tread, the first receptacle having a substantially semi-circular cross-sectional surface;
• a second elongated receptacle extending from the bottom of the tread, the second receptacle having a substantially semi-circular cross-sectional surface;
• wherein centerlines through the elongated receptacles are parallel to but offset from each other;
• wherein the receptacles are a flexible polymeric material;
• and
• wherein a nominal upper surface of the upper tread tilts at least 10° off of a plane through the centerlines of the receptacles.

A boat ladder apparatus comprising:

• an upper tread wall including a slip-resistant pattern thereon;
• a first tube-receiving formation located below the tread wall, the first tube-receiving formation having a partially circular cross-sectional shape;
• a second tube-receiving formation located below the tread wall, the second tube-receiving formation having a partially circular cross-sectional shape;
• and
• a boat-ladder comprising a pair of upwardly elongated rails with steps spanning between the rails, at least one of the steps including a pair of tubes with parallel middle sections, the tube-receiving formations snapping onto the tubes in a fastener-free manner, and the upper tread wall entirely covering tops of the tubes and extending past inboard and outboard surfaces of the tubes to provide a larger foot-engaging area as compared to only an area provided by the tubes.

A boat ladder apparatus comprising:

• a molded upper tread including a logo between elongated grooves on an upper surface thereof;
• a first receiving formation located below the tread, the first receiving formation having a partially circular cross-sectional shape;
• a second receiving formation located below the tread, the second receiving formation having a partially circular cross-sectional shape;
• and
• a boat-ladder comprising a pair of upwardly elongated rails with a step spanning between the rails, the receiving formations snapping onto the step in a fastener-free manner, and the upper tread covering tops of the step and having a larger foot-receiving area than the step.
