I'm currently planning for an upcoming Dungeons and Dragons campaign, the Ghosts of Saltmarsh. It is an anthology of linked adventures, most of which are adapted from older modules. The first adventure is an old 80s adventure, The Sinister Secret of Saltmarsh. In the second part of the adventure, the group must sneak onto the Sea Ghost, a smuggler's ship.
The group may have the opportunity to acquire the ship; so I suspected that it might be a fun model project. I apologise in advance for the poor quality of my sketches; it has been years since I sketched anything, and I was never very good. Still, I think it gives you a basic idea.
I've purchased a couple of large 6mm thick sheets of high-density foam that I will use to construct the floor of each level of the ship. I will probably need to reinforce this with some MDF. I'm planning on using something like artist board to construct the external walls; I'm considering using card sheeting to construct planking on the external walls and balsa wood for the internal walls- this will hopefully provide some strength and structure.
I'm looking forward to this construction, I suspect that there will be a lot of mistake made and a lot to learn.
Cheers
Andy
