Biilmann SD 1735: the only trailer of this brand outside the named ranges, model year 2012, 3,500 kg gross weight, 760 kg unladen weight
This page carries the only trailer model of Biilmann that the register did not assign to a named range: the SD 1735 from 2012. The narrow track and the load spread across three axles point to a boat trailer rather than a trailer with a closed box body.

The SD 1735 has a gross weight of 3,500 kg against an unladen weight of 760 kg, giving a payload of 2,740 kg. At a width of only 2,160 mm and an axle spacing of 4,780 mm, it stands on three axles, an unusually fine load spread for a 3.5-tonne trailer, typical for carrying a long but light watercraft without local flexing.
With a gross weight of 3,500 kg, the SD 1735 falls into EU category O2, where the brakes are usually an overrun design. The narrow build under 2.2 m stays below many slipway width limits and eases manoeuvring on narrow access roads to the water.
On a used boat trailer, what counts especially is corrosion on frame and axles, which often stand in salt or fresh water, the condition of the rollers and skids of the cradle, the function of the overrun brake despite frequent contact with water, and the tightness of the wheel bearings, which fail more often on boat trailers than on road trailers. With three axles, it is also worth checking that all of them carry load evenly and that none of the tyres show uneven wear from an unbalanced load.

What to check before buying
- Search the frame and welds at the axle mounts — that is where cracks start.
- Check the brakes and the last inspection in the papers.
- Work the gross weight against the towing vehicle before buying.
- Compare the chassis number with the papers.
- Look at the floor, cover or body from the inside — rust does not show from outside.
