A boat wagon adapted to be pushed or moved along an underlying wagon supporting surface includes two legs and a legs interconnecting member. The horizontal distance between the legs can be adjusted. The legs interconnecting member is formed of a number of removable elements adapted to co-act with each other. The span between the legs is adapted for road transport by removing one or more of the removable elements. The legs can be adjusted to adapt to a second span for boat transport by fitting one or more of the removed elements to wagon related and leg associated sub-parts.
