A better way aboard.
Every boat and trailer combination is different. ShiftStep lets you adjust where the ladder sits, which way it faces and how steeply it rises.
Slide the base forward or backward along a suitable trailer beam to choose your mounting location.
Select 60°, 70° or 80° to suit the available space and reach. Adjust the step supports to match.
Choose from 16 indexed base positions, spaced at 22.5°, to point the steps towards your boarding position.

Nine positions shown. 0° faces forward towards the boat. Usable positions depend on clearance around the bow, winch and other equipment. Secure all adjustments before use.
An SS304 stainless-steel structure with stainless bolts, nuts, washers and mounting parts. The 60 × 40 × 3 mm rectangular mast carries three 280 mm steps, each with an anti-slip pad.
The base clamps around the trailer beam, so there is no drilling or welding, and no holes through the trailer's protective coating.
Insulating layers on the upper supports and lower clamps keep the stainless mounting surfaces off the galvanized beam. This protects the zinc coating and reduces galvanic corrosion when moisture is present.
Measure the outside width and height of the beam where you want to mount the ladder.
Open C-channel beams are not suitable. Shorter or longer bolts are available on request.
