We've just spent a couple of days staying in a hotel overlooking Harwich harbour.
You see things like this chuntering past and you can't help but think 'could I make a model of that'. Probably not, but it does no harm to dream.
Maybe I should try the lightship, no bother with motors, shafts, batteries etc with that one. I did make a Revell plastic kit of a UK lightship, many, many moons ago.
Incidentally it's the Stena Forerunner, Ro-Ro freight, it does the Harwich, Parkeston - Rotterdam return trip everyday.
