There is a new free model to download from http://www.papershipwright.co.uk!
It is Doug Holden's model of a LASH lighter. LASH stands for Lighter Aboard Ship. These lighters were designed for carrying bulk cargo and, while they could float and be towed by small tugs, they were carried over longer distances by larger carrier ships like the "Munchen".
Enjoy making the model and please encourage Mathias Nöring to complete his model of the Munchen so we have something we can put the lighter on!
