Each machine has been hand finished with Danish Oil giving a deep lustre an warmth to the wood. Wood has been chosen due to its marvellous engineering properties, primary amongst these is its ability to absorb sound & vibration enhancing the Water Rower's quietness & smoothness of use.

For reasons of ecology, all our woods are harvested from replenishable forests.
