The very best for your boat
O.B. Wiik’s cradles are the most robust cradles on the market. Made of 48 mm pipes in anodised aluminium and joints in galvanised steel the cradles will withstand all types of weather conditions.
Our laying-up cradles come in standard sizes, but we can tailor cradles to meet individual requirements. O.B. Wiik also supplies boat cover tarpaulins. Unable to find a standard size that meets your needs? We will manufacture a tarpaulin to your measurements and specifications.
We also supply a harbour tarpaulin we call “Captain’s Roll On”, which suits most pleasure boats up to 16 feet and comes in three standard sizes.
Cradles
The cradles are produced of solid 48 mm anodised aluminium tubes and with 44 mm anodised tubes in the telescopic (support) legs.
All connectors and joints are made of electro-galvanised steel. Frames are available in standard packages or custom-made to specifications.
Boat tarpaulin
Parts
The tarpaulin frame from O.B. Wiik AS can be adapted to all boat types. 48 mm aluminium tubes are kept in stock in lengths of 1, 2, 3, 4 and 6 metres. Tubes for the variable adjustment of deck supports are adapted to an inner diameter of 48 mm and provided in 1 metre lengths. Standard deck supports consist of one 48 mm tube in a 1 metre length and one 44 mm tube in a 2 metre length, both in 1 metre lengths. These can also be adjusted variably from 1 metre to approx. 1.80 metres. Deck supports are also available in 2+1 m, 3+1 m, etc.
Telescopic legs are placed downwards towards the deck. One telescopic leg is placed straight down (see illustration). The frame can then be adjusted upwards or downwards as needed. To secure the frame, attach rope or a ratchet strap from the top of the frame down and down into the railing.
The frame should be attached to the boat using rope fore and aft. All bolts must be tightened firmly. A tarpaulin of the right size attached by a rope running under the keep of the boat (or containers with water/sand attached to the eyelets) will ensure that the tarpaulin and frame do not shift during the winter.
Keep in mind the importance of proper ventilation under the tarpaulin to prevent rot and mildew.
Also remember that a tarpaulin superstructure that is too high can cause windage problems and one that is too low can cause snow and water to accumulate.
If you choose both a Wiik frame and tarpaulin, the boat will be properly covered. See the separate price lists for rentals and sales of tarpaulins. Tarpaulins can also be custom-made in our factory.

None of the deck supports should be placed vertically on the deck because this weakens protection against crosswind. The best configuration is to use three support beams (20-25 foot boat). Two are placed against the railing and one perpendicular to the deck/superstructure.

Høyblokka
Currently, "Høyblokka" is being restored in the Government Quarter behind a specially made canvas from O.B.Wiik. The special thing about the canvas is that it has a motif of Høyblokka so the public can still see the building even if scaffolding has been set up and the work is going well.
