Like the print-out for the ship try doing it in small modules...
1... It won't be an all-out huge project (It will but you feel like you've accomplished something as things go together)
2... You can inter-change the sections to make other vessels.

That's my plan once I have the coin to get the molds and casting material.

P.S. You could try the Wayfarer as a starter if you still feel over-whelmed
