I'm not sure what exactly you mean with 'solid ends'? English isn't my mother's tongue you see.
The hull was designed by user 'Askarsil' on thingiverse: https://www.thingiverse.com/thing:4254426
But that is only the overall structure (hull + upper structure. No masts, jib, winch, etc...). His design however is made to be printed (instead of casting in polyester resin). The hull is divided into 7 pieces to fit 3D printers, and he has included mountholes to insert guides to make the pieces line up when put together.
Now that i found the website of this ship's original, with plenty of pictures; i definitely want to turn this into a watertight RC model. So i'll be gluing the hull pieces together, then treating the hull with 3DGloop to make it watertight. And complete Askarsil's design with mast, jib, doors, windows, winch and have ya.
