Slipper Springs, Galvanised
Galvanised Slipper Springs are the favoured trailer spring for boat trailers.

When purchasing slipper springs for a tandem boat trailer, the loading is calculated at 120%.

For example, when choosing a spring set to carry 1000kg, choose a set for 1200kg.

Slipper springs do not share the load between axles, therefore, springs need to be selected 20% in excess to their capacity.

The best way to explain is, image a tandem trailer with the left rear wheel on the top of the gutter. The left front wheel will be in the air.

The total load of the left-hand side of the trailer is loaded onto the rear axle only.

Therefore, the regulation states slipper spring must be 120% of the ATM.
