Three adjustments. One comfortable 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.
Together, these adjustments help you find a position with clearance around the bow, winch, trolling motor and other equipment. Available positions depend on your trailer layout. Secure all adjustments before use.
Stainless steel, down to the hardware
ShiftStep combines an SS304 stainless-steel structure with stainless-steel bolts, nuts, washers and mounting components.
The rectangular mast supports three 280 mm wide steps, each fitted with an anti-slip pad. The base clamps around the trailer beam, so installation requires no drilling or welding.
Insulating layers on the upper supports and lower clamps separate the stainless-steel mounting surfaces from the galvanized trailer beam. This helps protect the zinc coating and reduces direct contact between the different metals—a factor in galvanic corrosion when moisture is present.
The clamp-on design also avoids making holes or welds through the trailer’s protective coating.
Designed and manufactured by DonMarine in Bulgaria, with direct help available for fitment and installation.
Will ShiftStep fit your trailer?
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 mounting bolts are available on request.

Frequently asked questions
Do I need to modify my trailer?
No drilling or welding is required. ShiftStep clamps around a suitable closed square or rectangular trailer beam.
Can I adjust it around my winch or trolling motor?
The sliding base, indexed direction settings and three ladder angles give you several ways to position it. Check the available space around your equipment before ordering.
My beam is taller than 80 mm. Can I still fit it?
Longer mounting bolts are available on request. Send us the beam width, height and a photo so we can help check the installation.
Does it arrive assembled?
Assembly and positioning on your trailer are required. The illustrated manual explains the installation sequence and final tightening.
Is delivery included in the price?
Shipping is charged separately and calculated at checkout.
Can I get help with installation?
Yes. Contact DonMarine at info@donmarine.eu with your question and photos of your setup.
Before climbing
Use only with the trailer stationary and secured against movement. One person at a time, up to 150 kg including carried items. Check the ladder and its fixings before use, and follow the full installation and user manual.
