The POLAR 590 BK is a caravan from POLAR (EU vehicle class O2), built from 2008 to 2014. It is 7,705 mm long and 2,510 mm wide, weighs 1,400 kg unladen and has a permitted gross weight of 1,600 kg.
Payload for the POLAR 590 BK, i.e. permitted gross weight minus unladen weight, is 200 kg. For a caravan this covers everything that travels along: gas bottles, awning, water, crockery and luggage; retrofitted equipment such as a motor mover or air conditioning reduces the margin further.
Under EU licensing rules, a category B licence allows a combination of towing vehicle and this trailer up to 3,500 kg permitted total mass – so the towing vehicle may weigh at most 1,900 kg. Code 96 on a B licence raises the limit to 4,250 kg (towing vehicle up to 2,650 kg); beyond that a BE licence is required. Being over 750 kg, the trailer must be braked, and the towing vehicle needs a braked towing capacity of at least 1,600 kg.
Among the 213 caravans from POLAR with a stated length, the POLAR 590 BK at 7,705 mm is in the middle of the range (rank 84); the range runs from 4,150 to 9,500 mm. The Finnish vehicle register lists 4 units.
POLAR – trailers up to 3.5 t (class O2): the collective page of Scandinavian boat and car trailers outside the named ranges, 420 to 560 weight classes, 200 to 2,010 kg unladen weight, up to 2.8 t gross weight
This page gathers the POLAR class O2 trailers the register could not assign to a named range. Class O2 covers trailers up to 3.5 tonnes gross weight; POLAR is known in Northern Europe chiefly for boat trailers, which shows in the long versions in the register and in codes such as GS, GL and BKX for different keel-support and roller fittings. The model numbers (420, 520, 560) clearly name the weight or frame-size class, the suffix after the slash often the frame length in centimetres.

The register lists here 201 versions with unladen weights from 200 to 2,010 kg, gross weights from 1,000 to 2,800 kg, lengths from 4,150 to 9,500 mm and widths from 1,860 to 2,550 mm – long, narrow dimensions typical of boat transport.
Boat trailers of this size are a mass market in Scandinavia and Northern European watersports, with adjustable keel supports and roller tracks as the central equipment feature for different hull shapes.
When buying used, what matters is rust on the chassis, especially in the part that touches water, the condition and free movement of rollers and keel supports, the function of the wheel bearings (often stressed by submersion during launching), the condition of the brake system where fitted, and the tightness of the lighting; a valid roadworthiness inspection is basic equipment. Spares run through the Nordic boat-accessory trade.
